| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, commodities, currencies, funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in the underlying reference asset(s). Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:

| Return Stacked(R) Bonds & Futures Yield ETF | Futures Contracts [Member] | ||||||||||
| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | Futures Contracts. Risks of futures contracts include: (i) an imperfect correlation between the value of the futures contract and the underlying asset; (ii) possible lack of a liquid secondary market; (iii) the inability to close a futures contract when desired; (iv) losses caused by unanticipated market movements, which may be unlimited; (v) an obligation for the Fund to make daily cash payments to maintain its required margin, particularly at times when the Fund may have insufficient cash; and (vi) unfavorable execution prices from rapid selling.

| Return Stacked(R) Bonds & Futures Yield ETF | Swaps [Member] | ||||||||||
| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | Swaps. Swap agreements involve the risk that the party with whom the Fund has entered into the swap will default on its obligation to pay the Fund. Additionally, certain unexpected market events or significant adverse market movements could result in the Fund not holding enough assets to be able to meet its obligations under the agreement. Such occurrences may negatively impact the Fund’s ability to implement its principal investment strategies and could result in losses to the Fund.

| Return Stacked(R) Bonds & Futures Yield ETF | Cayman Subsidiary Risk [Member] | ||||||||||
| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | Cayman Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The futures contracts and other investments held by the Subsidiary are subject to the same economic risks that apply to similar investments if held directly by the Fund. The Subsidiary is not registered under the 1940 Act, and, unless otherwise noted in this Prospectus, is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to continue to operate as it does currently and could adversely affect the Fund. For example, the Cayman Islands does not currently impose any income, corporate or capital gains tax or withholding tax on the Subsidiary. If Cayman Islands law changes such that the Subsidiary must pay Cayman Islands taxes, Fund shareholders would likely suffer decreased investment returns. In addition, the Subsidiary is also subject to many of the risks to which each Fund is subject, such as tax risks, commodity related risks, and market and data risks.

| Return Stacked(R) Bonds & Futures Yield ETF | Bond Risks [Member] | ||||||||||
| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | Bond Risks. The Fund will be subject to bond and fixed income risks through its investments in U.S. Treasury securities, broad-based bond ETFs, U.S. Treasury and fixed income futures contracts, as well as swaps. Changes in interest rates generally will cause the value of fixed-income and bond instruments held by Fund (or underlying ETFs) to vary inversely to such changes. Prices of longer-term fixed-income instruments generally fluctuate more than the prices of shorter-term fixed income instruments as interest rates change. Fixed-income instruments that are fixed-rate are generally more susceptible than floating rate loans to price volatility related to changes in prevailing interest rates. The prices of floating rate fixed-income instruments tend to have less fluctuation in response to changes in interest rates, but will have some fluctuation, particularly when the next interest rate adjustment on such security is further away in time or adjustments are limited in amount over time. The Fund (or underlying ETFs) may invest in short-term securities that, when interest rates decline, affect the Fund’s (or underlying ETF’s) yield as these securities mature or are sold and the Fund (or underlying ETFs) purchases new short-term securities with lower yields. An obligor’s willingness and ability to pay interest or to repay principal due in a timely manner may be affected by, among other factors, its cash flow.

|||||||||
| Return Stacked(R) Bonds & Futures Yield ETF | Equity Market Risk [Member] | ||||||||||
| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | Equity Market Risk. By virtue of the Fund’s investments in equity index futures agreements and/or equity swaps, the Fund is exposed to common stocks indirectly which subjects the Fund to equity market risk. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from specific issuers. Equity securities may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests.
|
|||||||||
| Return Stacked(R) Bonds & Futures Yield ETF | Commodities Risk [Member] | ||||||||||
| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | Commodities Risk. Exposure to the commodities markets may subject the Fund to greater volatility than investments in traditional securities. The value of commodity-linked derivative investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, embargoes, tariffs and international economic, political and regulatory developments.
|
|||||||||
| Return Stacked(R) Bonds & Futures Yield ETF | Commodity-Linked Derivatives Tax Risk [Member] | ||||||||||
| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | Commodity-Linked Derivatives Tax Risk. The tax treatment of commodity-linked derivative instruments may be adversely affected by changes in legislation, regulations, or other legally binding authority. As a RIC, the Fund must derive at least 90% of its gross income each taxable year from certain qualifying sources of income under the Code. If, as a result of any adverse future legislation, U.S. Treasury regulations, and/or guidance issued by the Internal Revenue Service (the “IRS”), the income of the Fund from certain commodity-linked derivatives, including income from the Fund’s investments in the Subsidiary, were treated as non-qualifying income, the Fund may fail to qualify as a RIC and/or be subject to federal income tax at the Fund level. The uncertainty surrounding the treatment of certain derivative instruments under the qualification tests for a RIC may limit the Fund’s use of such derivative instruments.
The Fund intends to limit its investment in the Subsidiary to no more than 25% of the value of its total assets in order to satisfy certain asset diversification requirements for taxation as a regulated investment company. The Fund intends to manage the exposure to the Subsidiary so that the Fund’s investments in the Subsidiary do not exceed 25% of the total assets at the end of any quarter. If the Fund’s investments in the Subsidiary were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.
|
|||||||||
| Return Stacked(R) Bonds & Futures Yield ETF | Commodity Pool Regulatory Risk [Member] | ||||||||||
| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | Commodity Pool Regulatory Risk. The Fund’s investment exposure to certain instruments will cause it to be deemed to be a commodity pool, thereby subjecting the Fund to regulation under the Commodity Exchange Act of 1936, as amended (“CEA”), and CFTC rules. The Adviser is registered as a commodity pool operator (“CPO”), ReSolve is registered as a CPO as well as a commodity trading advisor (“CTA”), RAM is registered as a CTA, and the Fund will be operated in accordance with applicable CFTC rules, as well as the regulatory scheme applicable to registered investment companies. Registration as a CPO or CTA imposes additional compliance obligations on the Adviser, ReSolve and RAM, as applicable, and the Fund related to additional laws, regulations, and enforcement policies, which could increase compliance costs and may affect the operations and financial performance of the Fund. However, the Fund’s status as a commodity pool and the Adviser’s, ReSolve’s and RAM’s registration as a CPO (and/or CTA, as applicable), are not expected to materially adversely affect the Fund’s ability to achieve its investment objective. The CFTC has not passed on the adequacy of this Prospectus.
|
|||||||||
| Return Stacked(R) Bonds & Futures Yield ETF | Tax Risk [Member] | ||||||||||
| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | Tax Risk. The Fund intends to treat any income it may derive from the Subsidiary as “qualifying income” under the provisions of the Code applicable to RICs. The IRS has issued numerous private letter rulings (“PLRs”) provided to third parties not associated with the Fund or its affiliates (which only those parties may rely on as precedent) concluding that similar arrangements resulted in qualifying income. Many of such PLRs have now been revoked by the IRS. In March of 2019, the IRS published Regulations that concluded that income from a corporation similar to the Subsidiary would be qualifying income, if the income is related to the Fund’s business of investing in stocks or securities. Although the Regulations do not require distributions from the Subsidiary, the Fund intends to cause the Subsidiary to make distributions that would allow the Fund to make timely distributions to its shareholders. The Fund generally will be required to include in its own taxable income the income of the Subsidiary for a tax year, regardless of whether the Fund receives a distribution of the Subsidiary’s income in that tax year, and this income would nevertheless be subject to the distribution requirement for qualification as a regulated investment company and would be taken into account for purposes of the 4% excise tax.
If the Fund did not qualify as a RIC for any taxable year and certain relief provisions were not available, the Fund’s taxable income would be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. In such event, in order to re-qualify for taxation as a RIC, the Fund might be required to recognize unrealized gains, pay substantial taxes and interest and make certain distributions. This would cause investors to incur higher tax liabilities than they otherwise would have incurred and would have a negative impact on Fund returns. In such event, the Fund’s Board of Trustees may determine to reorganize or close the Fund or materially change the Fund’s investment objective and strategies. In the event that the Fund fails to qualify as a RIC, the Fund will promptly notify shareholders of the implications of that failure.

|||||||||
| Return Stacked(R) Bonds & Futures Yield ETF | Credit Risk [Member] | ||||||||||
| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | Credit Risk. Credit risk refers to the possibility that the issuer of a security will not be able to make principal and interest payments when due. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer. Securities rated in the four highest categories by the rating agencies are considered investment grade but they may also have some speculative characteristics. Investment grade ratings do not guarantee that the issuer will not default on its payment obligations or that bonds will not otherwise lose value.
|
|||||||||
| Return Stacked(R) Bonds & Futures Yield ETF | Currency Risk [Member] | ||||||||||
| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | Currency Risk. Currency risk is the risk that changes in currency exchange rates will negatively affect securities denominated in, and/or receiving revenues in, foreign currencies. The liquidity and trading value of foreign currencies could be affected by global economic factors, such as inflation, interest rate levels, and trade balances among countries, as well as the actions of sovereign governments and central banks. Adverse changes in currency exchange rates (relative to the U.S. dollar) may erode or reverse any potential gains from the Fund’s (or an underlying ETF’s) investments in securities denominated in a foreign currency or may widen existing losses.
|
|||||||||
| Return Stacked(R) Bonds & Futures Yield ETF | Foreign Investment Risk [Member] | ||||||||||
| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | Foreign Investment Risk. The Fund may invest in equity index futures and swaps on foreign equity investments. Such investments involve certain risks not involved in domestic investments and may experience more rapid and extreme changes in value than investments in securities of U.S. companies. Financial markets in foreign countries often are not as developed, efficient, or liquid as financial markets in the United States, and therefore, the prices of non-U.S. securities and instruments can be more volatile. In addition, the Fund will be subject to risks associated with adverse political and economic developments in foreign countries, which may include the imposition of economic sanctions. Generally, there is less readily available and reliable information about non-U.S. issuers due to less rigorous disclosure or accounting standards and regulatory practices. Since foreign exchanges may be open on days when the Fund does not price its Shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s Shares. Conversely, Shares may trade on days when foreign exchanges are closed. Investment in foreign securities may involve higher costs than investment in U.S. securities, including higher transaction and custody costs as well as the imposition of additional taxes by foreign governments. Each of these factors can make investments in the Fund more volatile and potentially less liquid than other types of investments.
|
|||||||||
| Return Stacked(R) Bonds & Futures Yield ETF | Interest Rate Risk [Member] | ||||||||||
| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | Interest Rate Risk. Interest rate risk is the risk that prices of fixed income securities generally increase when interest rates decline and decrease when interest rates increase. The Fund may lose money if short-term or long-term interest rates rise sharply or otherwise change in a manner not anticipated by Newfound or ReSolve, as the case may be.
|
|||||||||
| Return Stacked(R) Bonds & Futures Yield ETF | High Portfolio Turnover Risk [Member] | ||||||||||
| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | High Portfolio Turnover Risk. The Fund may actively and frequently trade all or a significant portion of the Fund’s holdings. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains.
|
|||||||||
| Return Stacked(R) Bonds & Futures Yield ETF | Leverage Risk [Member] | ||||||||||
| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | Leverage Risk. As part of the Fund’s principal investment strategy, the Fund will make investments in futures and/or swaps to gain long and short exposure across four major asset classes (commodities, currencies, fixed income and equities). These derivative instruments provide the economic effect of financial leverage by creating additional investment exposure to the underlying instrument, as well as the potential for greater loss. You could lose all or substantially all of your investment in the Fund should the Fund’s trading positions suddenly turn unprofitable. The net asset value of the Fund while employing leverage will be more volatile and sensitive to market movements.
|
|||||||||
| Return Stacked(R) Bonds & Futures Yield ETF | U.S. Government and U.S. Agency Obligations Risk [Member] | ||||||||||
| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | U.S. Government and U.S. Agency Obligations Risk. The Fund may invest in securities issued by the U.S. government or its agencies or instrumentalities. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so. Although U.S. Treasuries are backed by the U.S. government, those government policies may change both in terms of the payment of interest and in the payment of principal. Furthermore, while holding a Treasury until maturity can guarantee principal, selling a treasury prior to maturity or buying a treasury subsequent to issue date may put principal at risk.
|
|||||||||
| Return Stacked(R) Bonds & Futures Yield ETF | Underlying ETFs Risks [Member] | ||||||||||
| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | Underlying ETFs Risks. The Fund will incur higher and duplicative expenses because it invests in bond ETFs (“Underlying ETFs”). There is also the risk that the Fund may suffer losses due to the investment practices of the Underlying ETFs. The Fund will be subject to substantially the same risks as those associated with the direct ownership of securities held by the Underlying ETFs. Additionally, the market price of the shares of an Underlying ETF in which the Fund invests will fluctuate based on changes in the net asset value as well as changes in the supply and demand of its shares in the secondary market. It is also possible that an active secondary market for an Underlying ETF’s shares may not develop, and market trading in the shares of the Underlying ETF may be halted under certain circumstances. Underlying ETFs are also subject to the “ETF Risks” described below.
|
|||||||||
| Return Stacked(R) Bonds & Futures Yield ETF | Counterparty Risk [Member] | ||||||||||
| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | Counterparty Risk. Counterparty risk is the likelihood or probability that a party involved in a transaction might default on its contractual obligation. Where the Fund enters into derivative contracts that are exchange-traded, the Fund is subject to the counterparty risk associated with the Fund’s clearing broker or clearinghouse. Relying on a counterparty exposes the Fund to the risk that a counterparty will not settle a transaction in accordance with its terms and conditions because of a dispute over the terms of the contract (whether or not bona fide) or because of a credit or liquidity problem, thus causing the Fund to suffer a loss. If a counterparty defaults on its payment obligations to the Fund, this default will cause the value of an investment in the Fund to decrease. In addition, to the extent the Fund deals with a limited number of counterparties, it will be more susceptible to the credit risks associated with those counterparties. |

| Risk [Text Block] | Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

The Fund may, at times, hold illiquid investments, by virtue of the absence of a readily available market for certain of its investments, or because of legal or contractual restrictions on sales. The Fund could lose money if it is unable to dispose of an investment at a time or price that is most beneficial to the Fund.

| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | Models and Data Risk. The composition of the Fund’s (and Subsidiary’s) portfolio is heavily dependent on proprietary investment models as well as information and data supplied by third parties (“Models and Data”). When Models and Data prove to be incorrect or incomplete, any decisions made in reliance thereon may lead to the inclusion or exclusion of securities from the Fund’s (or Subsidiary’s) portfolio that would have been excluded or included had the Models and Data been correct and complete.

|||||||||
| Return Stacked(R) Bonds & Futures Yield ETF | Newer Fund Risk [Member] | ||||||||||
| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | Newer Fund Risk. The Fund is a recently organized management investment company with a limited operating history. As a result, prospective investors have only a limited track record or history on which to base their investment decisions. There can be no assurance that the Fund will grow to or maintain an economically viable size.
|
|||||||||
| Return Stacked(R) Bonds & Futures Yield ETF | Operational Risk [Member] | ||||||||||
| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | Operational Risk. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund, Adviser, Newfound, ReSolve, and RAM seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

| Return Stacked(R) Bonds & Futures Yield ETF | Risk Nondiversified Status [Member] | ||||||||||
| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.

| Risk [Text Block] | Commodity Pool Regulatory Risk. The Fund’s investment exposure to certain instruments will cause it to be deemed to be a commodity pool, thereby subjecting the Fund to regulation under the Commodity Exchange Act of 1936, as amended (“CEA”), and CFTC rules. The Adviser is registered as a commodity pool operator (“CPO”), ReSolve is registered as a CPO as well as a commodity trading advisor (“CTA”), RAM is registered as a CTA, and the Fund will be operated in accordance with applicable CFTC rules, as well as the regulatory scheme applicable to registered investment companies. Registration as a CPO or CTA imposes additional compliance obligations on the Adviser, Resolve and RAM, as applicable, and the Fund related to additional laws, regulations, and enforcement policies, which could increase compliance costs and may affect the operations and financial performance of the Fund. However, the Fund’s status as a commodity pool and the Adviser’s, ReSolve’s and RAM’s registration as a CPO (and/or CTA, as applicable), are not expected to materially adversely affect the Fund’s ability to achieve its investment objective. The CFTC has not passed on the adequacy of this Prospectus.

| Risk [Text Block] | Tax Risk. The Fund intends to treat any income it may derive from the Subsidiary as “qualifying income” under the provisions of the Code applicable to RICs. The IRS has issued numerous private letter rulings (“PLRs”) provided to third parties not associated with the Fund or its affiliates (which only those parties may rely on as precedent) concluding that similar arrangements resulted in qualifying income. Many of such PLRs have now been revoked by the IRS. In March of 2019, the IRS published Regulations that concluded that income from a corporation similar to the Subsidiary would be qualifying income, if the income is related to the Fund’s business of investing in stocks or securities. Although the Regulations do not require distributions from the Subsidiary, the Fund intends to cause the Subsidiary to make distributions that would allow the Fund to make timely distributions to its shareholders. The Fund generally will be required to include in its own taxable income the income of the Subsidiary for a tax year, regardless of whether the Fund receives a distribution of the Subsidiary’s income in that tax year, and this income would nevertheless be subject to the distribution requirement for qualification as a regulated investment company and would be taken into account for purposes of the 4% excise tax.
If the Fund did not qualify as a RIC for any taxable year and certain relief provisions were not available, the Fund’s taxable income would be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. In such event, in order to re-qualify for taxation as a RIC, the Fund might be required to recognize unrealized gains, pay substantial taxes and interest and make certain distributions. This would cause investors to incur higher tax liabilities than they otherwise would have incurred and would have a negative impact on Fund returns. In such event, the Fund’s Board of Trustees may determine to reorganize or close the Fund or materially change the Fund’s investment objective and strategies. In the event that the Fund fails to qualify as a RIC, the Fund will promptly notify shareholders of the implications of that failure.

Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer. Securities rated in the four highest categories by the rating agencies are considered investment grade but they may also have some speculative characteristics. Investment grade ratings do not guarantee that the issuer will not default on its payment obligations or that bonds will not otherwise lose value.

| Risk [Text Block] | Currency Risk. Currency risk is the risk that changes in currency exchange rates will negatively affect securities denominated in, and/or receiving revenues in, foreign currencies. The liquidity and trading value of foreign currencies could be affected by global economic factors, such as inflation, interest rate levels, and trade balances among countries, as well as the actions of sovereign governments and central banks. Adverse changes in currency exchange rates (relative to the U.S. dollar) may erode or reverse any potential gains from the Fund’s (or an underlying ETF’s) investments in securities denominated in a foreign currency or may widen existing losses.

| Return Stacked(R) Bonds & Managed Futures ETF | Foreign Investment Risk [Member] | ||||||||||
| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | Foreign Investment Risk. The Fund may invest in equity index futures and swaps on foreign equity investments. Such investments involve certain risks not involved in domestic investments and may experience more rapid and extreme changes in value than investments in securities of U.S. companies. Financial markets in foreign countries often are not as developed, efficient, or liquid as financial markets in the United States, and therefore, the prices of non-U.S. securities and instruments can be more volatile. In addition, the Fund will be subject to risks associated with adverse political and economic developments in foreign countries, which may include the imposition of economic sanctions. Generally, there is less readily available and reliable information about non-U.S. issuers due to less rigorous disclosure or accounting standards and regulatory practices. Since foreign exchanges may be open on days when the Fund does not price its Shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s Shares. Conversely, Shares may trade on days when foreign exchanges are closed. Investment in foreign securities may involve higher costs than investment in U.S. securities, including higher transaction and custody costs as well as the imposition of additional taxes by foreign governments. Each of these factors can make investments in the Fund more volatile and potentially less liquid than other types of investments.

As part of the Fund’s principal investment strategy, the Fund will make investments in futures and/or swaps to gain long and short exposure across four major asset classes (commodities, currencies, fixed income and equities). These derivative instruments provide the economic effect of financial leverage by creating additional investment exposure to the underlying instrument, as well as the potential for greater loss. You could lose all or substantially all of your investment in the Fund should the Fund’s trading positions suddenly turn unprofitable. The net asset value of the Fund while employing leverage will be more volatile and sensitive to market movements.

| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | U.S. Government and U.S. Agency Obligations Risk. The Fund may invest in securities issued by the U.S. government or its agencies or instrumentalities. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so. Although U.S. Treasuries are backed by the U.S. government, those government policies may change both in terms of the payment of interest and in the payment of principal. Furthermore, while holding a Treasury until maturity can guarantee principal, selling a treasury prior to maturity or buying a treasury subsequent to issue date may put principal at risk.

Where the Fund enters into derivative contracts that are exchange-traded, the Fund is subject to the counterparty risk associated with the Fund’s clearing broker or clearinghouse. Relying on a counterparty exposes the Fund to the risk that a counterparty will not settle a transaction in accordance with its terms and conditions because of a dispute over the terms of the contract (whether or not bona fide) or because of a credit or liquidity problem, thus causing the Fund to suffer a loss. If a counterparty defaults on its payment obligations to the Fund, this default will cause the value of an investment in the Fund to decrease. In addition, to the extent the Fund deals with a limited number of counterparties, it will be more susceptible to the credit risks associated with those counterparties. |

The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in the underlying reference asset(s). Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested.

| Risk [Text Block] | Bond Risks. The Fund will be subject to bond and fixed income risks through its investments in U.S. Treasury securities, U.S. Treasury ETFs, U.S. Treasury futures contracts, as well as swaps. Changes in interest rates generally will cause the value of fixed-income and bond instruments held by Fund to vary inversely to such changes. Prices of longer-term fixed-income instruments generally fluctuate more than the prices of shorter-term fixed income instruments as interest rates change. Fixed-income instruments that are fixed-rate are generally more susceptible than floating rate loans to price volatility related to changes in prevailing interest rates. The prices of floating rate fixed-income instruments tend to have less fluctuation in response to changes in interest rates, but will have some fluctuation, particularly when the next interest rate adjustment on such security is further away in time or adjustments are limited in amount over time. The Fund may invest in short-term securities that, when interest rates decline, affect the Fund’s yield as these securities mature or are sold and the Fund purchases new short-term securities with lower yields. An obligor’s willingness and ability to pay interest or to repay principal due in a timely manner may be affected by, among other factors, its cash flow.

| Return Stacked(R) Bonds & Merger Arbitrage ETF | Short Sale Risk [Member] | ||||||||||
| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | Short Sale Risk. The Fund enters into a short sale by selling a security it has borrowed (typically from a broker or other institution). If the market price of a security increases after the Fund borrows the security, the Fund will suffer a (potentially unlimited) loss when it replaces the borrowed security at the higher price. In certain cases, purchasing a security to cover a short position can itself cause the price of the security to rise further, thereby exacerbating the loss. In addition, the Fund may not always be able to borrow the security at a particular time or at an acceptable price. Short sales also involve transaction and financing costs that will reduce potential Fund gains and increase potential Fund losses. In addition, the Underlying Funds in which the Fund invests may also enter into short sales, and the Fund will bear the risk of such use.

While the Fund’s Merger Arbitrage portfolio generally seeks to track the performance, before fees and expenses, of the Underlying Index, the performance of the Fund’s Merger Arbitrage portfolio and its Underlying Index may differ from each other for a variety of reasons. For example, the Fund incurs operating expenses and portfolio transaction costs not incurred by the Underlying Index. In addition, the Fund may not be fully invested in the securities and financial instruments of the Underlying Index at all times or may hold securities and financial instruments not included in the Underlying Index.

Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.

| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in the underlying reference asset(s). Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested.

| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | Bond Risks. The Fund will be subject to bond and fixed income risks through its investments in U.S. Treasury securities. Changes in interest rates generally will cause the value of fixed-income and bond instruments held by the Fund to vary inversely to such changes. Prices of longer-term fixed-income instruments generally fluctuate more than the prices of shorter-term fixed income instruments as interest rates change. Fixed-income instruments that are fixed-rate are generally more susceptible than floating rate loans to price volatility related to changes in prevailing interest rates. The prices of floating rate fixed-income instruments tend to have less fluctuation in response to changes in interest rates, but will have some fluctuation, particularly when the next interest rate adjustment on such security is further away in time or adjustments are limited in amount over time. The Fund may invest in short-term securities that, when interest rates decline, affect the Fund’s yield as these securities mature or are sold and the Fund purchases new short-term securities with lower yields.

Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from specific issuers. Equity securities may experience sudden, unpredictable drops in value or long periods of decline in value.

U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so. Although U.S. Treasuries are backed by the U.S. government, those government policies may change both in terms of the payment of interest and in the payment of principal. Furthermore, while holding a treasury until maturity can guarantee principal, selling a treasury prior to maturity or buying a treasury subsequent to issue date may put principal at risk.

Where the Fund enters into derivative contracts that are exchange-traded, the Fund is subject to the counterparty risk associated with the Fund’s clearing broker or clearinghouse. Relying on a counterparty exposes the Fund to the risk that a counterparty will not settle a transaction in accordance with its terms and conditions because of a dispute over the terms of the contract (whether or not bona fide) or because of a credit or liquidity problem, thus causing the Fund to suffer a loss. If a counterparty defaults on its payment obligations to the Fund, this default will cause the value of an investment in the Fund to decrease. In addition, to the extent the Fund deals with a limited number of counterparties, it will be more susceptible to the credit risks associated with those counterparties. |

In March of 2019, the IRS published Regulations that concluded that income from a corporation similar to the Subsidiary would be qualifying income, if the income is related to the Fund’s business of investing in stocks or securities. Although the Regulations do not require distributions from the Subsidiary, the Fund intends to cause the Subsidiary to make distributions that would allow the Fund to make timely distributions to its shareholders. The Fund generally will be required to include in its own taxable income the income of the Subsidiary for a tax year, regardless of whether the Fund receives a distribution of the Subsidiary’s income in that tax year, and this income would nevertheless be subject to the distribution requirement for qualification as a regulated investment company and would be taken into account for purposes of the 4% excise tax.
If the Fund did not qualify as a RIC for any taxable year and certain relief provisions were not available, the Fund’s taxable income would be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. In such event, in order to re-qualify for taxation as a RIC, the Fund might be required to recognize unrealized gains, pay substantial taxes and interest and make certain distributions. This would cause investors to incur higher tax liabilities than they otherwise would have incurred and would have a negative impact on Fund returns. In such event, the Fund’s Board of Trustees may determine to reorganize or close the Fund or materially change the Fund’s investment objective and strategies. In the event that the Fund fails to qualify as a RIC, the Fund will promptly notify shareholders of the implications of that failure.

| Risk [Text Block] | Credit Risk. Credit risk refers to the possibility that the issuer of a security will not be able to make principal and interest payments when due. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer. Securities rated in the four highest categories by the rating agencies are considered investment grade but they may also have some speculative characteristics. Investment grade ratings do not guarantee that the issuer will not default on its payment obligations or that bonds will not otherwise lose value.

Currency risk is the risk that changes in currency exchange rates will negatively affect securities denominated in, and/or receiving revenues in, foreign currencies. The liquidity and trading value of foreign currencies could be affected by global economic factors, such as inflation, interest rate levels, and trade balances among countries, as well as the actions of sovereign governments and central banks.

| Risk [Text Block] | Foreign Investment Risk. The Fund may invest in equity index futures and swaps on foreign equity investments. Such investments involve certain risks not involved in domestic investments and may experience more rapid and extreme changes in value than investments in securities of U.S. companies. Financial markets in foreign countries often are not as developed, efficient, or liquid as financial markets in the United States, and therefore, the prices of non-U.S. securities and instruments can be more volatile. In addition, the Fund will be subject to risks associated with adverse political and economic developments in foreign countries, which may include the imposition of economic sanctions. Generally, there is less readily available and reliable information about non-U.S. issuers due to less rigorous disclosure or accounting standards and regulatory practices. Since foreign exchanges may be open on days when the Fund does not price its Shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s Shares. Conversely, Shares may trade on days when foreign exchanges are closed. Investment in foreign securities may involve higher costs than investment in U.S. securities, including higher transaction and custody costs as well as the imposition of additional taxes by foreign governments. Each of these factors can make investments in the Fund more volatile and potentially less liquid than other types of investments.

U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so. Although U.S. Treasuries are backed by the U.S. government, those government policies may change both in terms of the payment of interest and in the payment of principal. Furthermore, while holding a treasury until maturity can guarantee principal, selling a Treasury prior to maturity or buying a treasury subsequent to issue date may put principal at risk.

Where the Fund enters into derivative contracts that are exchange-traded, the Fund is subject to the counterparty risk associated with the Fund’s clearing broker or clearinghouse. Relying on a counterparty exposes the Fund to the risk that a counterparty will not settle a transaction in accordance with its terms and conditions because of a dispute over the terms of the contract (whether or not bona fide) or because of a credit or liquidity problem, thus causing the Fund to suffer a loss. If a counterparty defaults on its payment obligations to the Fund, this default will cause the value of an investment in the Fund to decrease. In addition, to the extent the Fund deals with a limited number of counterparties, it will be more susceptible to the credit risks associated with those counterparties. |

The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in the underlying reference asset(s).

The Subsidiary is not registered under the 1940 Act, and, unless otherwise noted in this Prospectus, is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to continue to operate as it does currently and could adversely affect the Fund. For example, the Cayman Islands does not currently impose any income, corporate or capital gains tax or withholding tax on the Subsidiary.

| Risk [Text Block] | Bond Risks. The Fund will be subject to bond and fixed income risks through its investments in U.S. Treasury securities, and investments in U.S. Treasury and fixed income futures and swap contracts. Changes in interest rates generally will cause the value of fixed-income and bond instruments held by Fund to vary inversely to such changes. Prices of longer-term fixed-income instruments generally fluctuate more than the prices of shorter-term fixed income instruments as interest rates change. Fixed-income instruments that are fixed-rate are generally more susceptible than floating rate loans to price volatility related to changes in prevailing interest rates. The prices of floating rate fixed-income instruments tend to have less fluctuation in response to changes in interest rates, but will have some fluctuation, particularly when the next interest rate adjustment on such security is further away in time or adjustments are limited in amount over time. The Fund may invest in short-term securities that, when interest rates decline, affect the Fund’s yield as these securities mature or are sold and the Fund purchases new short-term securities with lower yields. An obligor’s willingness and ability to pay interest or to repay principal due in a timely manner may be affected by, among other factors, its cash flow.

The tax treatment of commodity-linked derivative instruments may be adversely affected by changes in legislation, regulations, or other legally binding authority. As a RIC, the Fund must derive at least 90% of its gross income each taxable year from certain qualifying sources of income under the Code. If, as a result of any adverse future legislation, U.S. Treasury regulations, and/or guidance issued by the Internal Revenue Service (the “IRS”), the income of the Fund from certain commodity-linked derivatives, including income from the Fund’s investments in the Subsidiary, were treated as non-qualifying income, the Fund may fail to qualify as RIC and/or be subject to federal income tax at the Fund level. The uncertainty surrounding the treatment of certain derivative instruments under the qualification tests for a RIC may limit the Fund’s use of such derivative instruments.
The Fund intends to limit its investment in the Subsidiary to no more than 25% of the value of its total assets in order to satisfy certain asset diversification requirements for taxation as a regulated investment company. The Fund intends to manage the exposure to the Subsidiary so that the Fund’s investments in the Subsidiary do not exceed 25% of the total assets at the end of any quarter. If the Fund’s investments in the Subsidiary were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance.

| Risk [Text Block] | Underlying ETFs Risks. The Fund will incur higher and duplicative expenses because it invests in U.S. equity ETFs (Underlying ETFs). There is also the risk that the Fund may suffer losses due to the investment practices of the Underlying ETFs. The Fund will be subject to substantially the same risks as those associated with the direct ownership of securities held by the Underlying ETFs. Additionally, the market price of the shares of an Underlying ETF in which the Fund invests will fluctuate based on changes in the net asset value as well as changes in the supply and demand of its shares in the secondary market. It is also possible that an active secondary market for an Underlying ETF’s shares may not develop, and market trading in the shares of the Underlying ETF may be halted under certain circumstances. Underlying ETFs are also subject to the “ETF Risks” described below.

| Risk [Text Block] | Counterparty Risk. Counterparty risk is the likelihood or probability that a party involved in a transaction might default on its contractual obligation. Where the Fund enters into derivative contracts that are exchange-traded, the Fund is subject to the counterparty risk associated with the Fund’s clearing broker or clearinghouse. Relying on a counterparty exposes the Fund to the risk that a counterparty will not settle a transaction in accordance with its terms and conditions because of a dispute over the terms of the contract (whether or not bona fide) or because of a credit or liquidity problem, thus causing the Fund to suffer a loss. If a counterparty defaults on its payment obligations to the Fund, this default will cause the value of an investment in the Fund to decrease. In addition, to the extent the Fund deals with a limited number of counterparties, it will be more susceptible to the credit risks associated with those counterparties. |

| Risk [Text Block] | Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, commodities, currencies, funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in the underlying reference asset(s). Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:

The futures contracts and other investments held by the Subsidiary are subject to the same economic risks that apply to similar investments if held directly by the Fund. The Subsidiary is not registered under the 1940 Act, and, unless otherwise noted in this Prospectus, is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to continue to operate as it does currently and could adversely affect the Fund. For example, the Cayman Islands does not currently impose any income, corporate or capital gains tax or withholding tax on the Subsidiary. If Cayman Islands law changes such that the Subsidiary must pay Cayman Islands taxes, Fund shareholders would likely suffer decreased investment returns. In addition, the Subsidiary is also subject to many of the risks to which the Fund is subject, such as tax risks, commodity related risks, and market and data risks.

Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from specific issuers.

| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | Commodity-Linked Derivatives Tax Risk. The tax treatment of commodity-linked derivative instruments may be adversely affected by changes in legislation, regulations, or other legally binding authority. As a RIC, the Fund must derive at least 90% of its gross income each taxable year from certain qualifying sources of income under the Code. If, as a result of any adverse future legislation, U.S. Treasury regulations, and/or guidance issued by the Internal Revenue Service (the “IRS”), the income of the Fund from certain commodity-linked derivatives, including income from the Fund’s investments in the Subsidiary, were treated as non-qualifying income, the Fund may fail to qualify as RIC and/or be subject to federal income tax at the Fund level. The uncertainty surrounding the treatment of certain derivative instruments under the qualification tests for a RIC may limit the Fund’s use of such derivative instruments.
The Fund intends to limit its investment in the Subsidiary to no more than 25% of the value of its total assets in order to satisfy certain asset diversification requirements for taxation as a regulated investment company. The Fund intends to manage the exposure to the Subsidiary so that the Fund’s investments in the Subsidiary do not exceed 25% of the total assets at the end of any quarter. If the Fund’s investments in the Subsidiary were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

The Adviser is registered as a commodity pool operator (“CPO”), ReSolve is registered as a CPO as well as a commodity trading advisor (“CTA”), RAM is registered as a CTA, and the Fund will be operated in accordance with applicable CFTC rules, as well as the regulatory scheme applicable to registered investment companies. Registration as a CPO or CTA imposes additional compliance obligations on the Adviser, ReSolve and RAM, as applicable, and the Fund related to additional laws, regulations, and enforcement policies, which could increase compliance costs and may affect the operations and financial performance of the Fund. However, the Fund’s status as a commodity pool and the Adviser’s, ReSolve’s and RAM’s registration as a CPO (and/or CTA, as applicable), are not expected to materially adversely affect the Fund’s ability to achieve its investment objective. The CFTC has not passed on the adequacy of this Prospectus.

| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | Tax Risk. The Fund intends to treat any income received by the Subsidiary as “qualifying income” under the provisions of the Code applicable to RICs. The IRS has issued numerous private letter rulings (“PLRs”) provided to third parties not associated with the Fund or its affiliates (which only those parties may rely on as precedent) concluding that similar arrangements resulted in qualifying income. Many of such PLRs have now been revoked by the IRS. In March of 2019, the IRS published Regulations that concluded that income from a corporation similar to the Subsidiary would be qualifying income. Although the Regulations do not require distributions from the Subsidiary, the Fund intends to cause the Subsidiary to make distributions that would allow the Fund to make timely distributions to its shareholders and to meet the requirement that the Subsidiary have a value not in excess of 25% of the Fund’s value at the close of a quarter. The Fund generally will be required to include in its own taxable income the income of the Subsidiary for a tax year, regardless of whether the Fund receives a distribution of the Subsidiary’s income in that tax year, and this income would nevertheless be subject to the distribution requirement for qualification as a regulated investment company and would be taken into account for purposes of the 4% excise tax.
If the Fund did not qualify as a RIC for any taxable year and certain relief provisions were not available, the Fund’s taxable income would be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. In such event, in order to re-qualify for taxation as a RIC, the Fund might be required to recognize unrealized gains, pay substantial taxes and interest and make certain distributions. This would cause investors to incur higher tax liabilities than they otherwise would have incurred and would have a negative impact on Fund returns. In such event, the Fund’s Board of Trustees may determine to reorganize or close the Fund or materially change the Fund’s investment objective and strategies. In the event that the Fund fails to qualify as a RIC, the Fund will promptly notify shareholders of the implications of that failure.

| Return Stacked(R) U.S. Stocks & Gold/Bitcoin ETF | Bitcoin Investment Risks [Member] | ||||||||||
| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | Bitcoin Investment Risks. The Fund’s indirect investment in bitcoin, through investment in bitcoin futures, swaps and/or bitcoin Underlying Funds, exposes it to the unique risks of this emerging innovation. Bitcoin’s price is highly volatile, and its market is influenced by the changing bitcoin network, fluctuating acceptance levels, and unpredictable usage trends. Not being a legal tender and operating outside central authority systems like banks, bitcoin faces potential government restrictions. For instance, some countries may limit or ban bitcoin transactions, negatively impacting its market value.
The risks associated with bitcoin include the possibility of fraud, theft, market manipulation, and security breaches in trading platforms. A small group of large bitcoin holders, known as “whales,” can significantly influence bitcoin’s price and may have the ability to manipulate the price. The largely unregulated nature of bitcoin and its trading venues heightens risks of fraudulent activities and market manipulation, which could affect bitcoin’s price. For example, if a group of miners gains control over a majority of the bitcoin network, they could manipulate transactions to their advantage. Historical instances have seen bitcoin trading venues shut down due to fraud or security breaches, often leaving investors without recourse and facing significant losses.
Updates to bitcoin’s software, proposed by developers, can lead to the creation of new digital assets, or “forks,” if not broadly adopted. This can impact bitcoin’s demand and the Fund’s performance. The extreme volatility of bitcoin’s market price can result in shareholder losses. Furthermore, the operation of bitcoin trading platforms may be disrupted or cease altogether due to various issues, further affecting bitcoin’s price and the Fund’s investments.
The value of bitcoin has historically been subject to significant speculation, making trading and investing in bitcoin reliant on market sentiment rather than traditional fundamental analysis.
Bitcoin’s price can be influenced by events unrelated to its security or utility, including instability in other speculative areas of the crypto/blockchain space, potentially leading to substantial declines in its value.
Risks associated with crypto asset trading platforms include fragmentation, regulatory non-compliance, and the possibility of enforcement actions by regulatory authorities, which could impact the valuation of bitcoin-linked derivatives held by the Fund.
The security of the Bitcoin Blockchain may be compromised if a single miner or group controls more than 50% of the network’s hashing power, where hashing power refers to the computational capacity used to validate and secure transactions on the blockchain.
Proposed changes to the bitcoin protocol may not be universally adopted, leading to the creation of competing blockchains (forks) with different assets and participants, exemplified by past forks like Bitcoin Cash and Bitcoin SV.
The Bitcoin Blockchain protocol may contain vulnerabilities that attackers could exploit to disrupt its operation, potentially compromising the security and reliability of the network.
Emerging alternative public blockchains, particularly those emphasizing privacy through technologies like zero-knowledge cryptography, pose risks and challenges to the dominance of the Bitcoin Blockchain as a payment system.
Common impediments to adopting the Bitcoin Blockchain as a payment network include slow transaction processing, variability in transaction fees, and the volatility of bitcoin’s price, which may deter widespread adoption by businesses and consumers.
The development and use of “Layer II solutions” are critical for the scalability and functionality of the Bitcoin Blockchain, but they also introduce risks such as off-chain transaction execution, which could affect transparency and security. Layer II solutions are off-chain protocols that improve scalability and reduce transaction costs by processing transactions outside the main blockchain network.
Adoption and use of other blockchains supporting advanced applications like smart contracts present challenges to the dominance of the Bitcoin Blockchain, potentially impacting its long-term relevance and utility in the evolving landscape of blockchain technology.
The Fund’s strategy may be harmed to the extent bitcoin is viewed less as a risk asset, and more as, like gold, a safe haven asset, resulting in the two assets having a much higher correlation and a less stable investment trajectory for the Fund.

| Risk [Text Block] | Gold Investment Risks. The Fund will not invest directly in gold but will gain exposure through gold futures and/or swap contracts and gold Underlying Funds. These investments are subject to significant risk due to the inherent volatility and unpredictability of the commodities markets. The value of these investments is typically derived from the price movements of physical gold or related economic variables. Price fluctuations in gold linked instruments can be swift and substantial, often showing a low correlation with the returns of traditional equity and bond markets and may not align with trends in other asset classes.
Numerous factors can influence the price of gold, including overall market movements, interest rate changes, and variations in global supply and demand. Additionally, the volume of gold imports and exports, production factors such as weather conditions, and technological advances in gold processing and mining can significantly impact gold prices. Increased hedging activities, economic conditions, regulatory developments, and political stability also play crucial roles. Furthermore, global supply and demand dynamics, political and economic events, inflation expectations, currency exchange rates, and investment activities of hedge funds and commodity funds can all affect gold prices. Sharp fluctuations in gold markets may result in potential losses. In addition, gold markets have experienced extended periods of flat or declining prices. Investors should also be aware that while gold is often used to preserve wealth, there is no assurance that it will maintain its long-term value in terms of purchasing power.

When trading derivatives, liquidity risks and counterparty risks are substantial. Managing futures contracts can be complex and may affect the performance of an Underlying Fund. The use of swap transactions is a highly specialized activity, which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Additionally, each Underlying Fund, and consequently the Fund, is dependent on blockchain technology, which brings technological and cybersecurity risks, along with custodial challenges for securely storing digital assets. The constantly evolving regulatory and legal landscape presents continuous compliance and valuation difficulties. Risks related to market concentration and network issues in the digital asset sector further add complexity. Moreover, operational intricacies in managing digital assets and potential market volatility can lead to losses for each Underlying Fund.

| Risk [Text Block] | Underlying Gold Fund Risks: Investing in an Underlying Fund that focuses on gold, either through direct holdings or indirectly via derivatives like futures contracts, carries significant risk due to the inherent volatility and unpredictability of the commodities markets. Underlying Funds that trade futures contracts are subject to derivatives risk, leverage risk, counterparty risk and futures contracts risk, among other risks. In addition, Underlying Funds holding gold directly face significant custodial and safeguarding risks regarding their gold holdings. There is an inherent danger of these gold bars being lost, damaged, stolen, or becoming inaccessible due to factors such as natural disasters or terrorism.

| Risk [Text Block] | Potentially No 1940 Act Protections. It is expected that one or more Underlying Funds will not be registered as an investment company subject to the 1940 Act. In addition, Underlying Funds that invest directly in bitcoin or gold are not subject to the 1940 Act. Accordingly, investors in such an Underlying Fund would not have the protections expressly provided by that statute, including: provisions preventing Underlying Fund insiders from managing an Underlying Fund to their benefit and to the detriment of shareholders; provisions preventing an Underlying Fund from issuing securities having inequitable or discriminatory provisions; provisions preventing management by irresponsible persons; provisions preventing the use of unsound or misleading methods of computing Underlying Fund earnings and asset value; provisions prohibiting suspension of redemptions (except under limited circumstances); provisions limiting fund leverage; provisions imposing a fiduciary duty on fund managers with respect to receipt of compensation for services; and provisions preventing changes in an Underlying Fund’s character without the consent of shareholders.

| Risk [Text Block] | Reverse Repurchase Agreement Risk. Similar to borrowing, reverse repurchase agreements provide the Fund with cash for investment purposes, which creates leverage and subjects the Fund to the risks of leverage. Reverse repurchase agreements also involve the risk that the other party may fail to return the securities in a timely manner or at all. The Fund could lose money if it is unable to recover the securities and/or if the value of collateral held by the Fund, including the value of the investments made with cash collateral, is less than the value of securities.

| Return Stacked(R) U.S. Stocks & Gold/Bitcoin ETF | Risk Nondiversified Status [Member] | ||||||||||
| Prospectus [Line Items] | ||||||||||
| Risk [Text Block] | Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.
