| Applied Finance Valuation Large Cap ETF | Equity Securities Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Securities Risk. Since it purchases equity securities, the Fund is subject to the risk that stock prices will fall over short or extended periods of time. Historically, the equity markets have moved in cycles, and the value of the Fund’s equity securities may fluctuate from day to day. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These factors contribute to price volatility, which is a principal risk of investing in the Fund.
|
| Applied Finance Valuation Large Cap ETF | Market Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk. The value of securities in the Fund’s overall portfolio will fluctuate and, as a result, the Fund’s share price may decline suddenly or over a sustained period. |
| Applied Finance Valuation Large Cap ETF | Management Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Management Risk. The strategies used by the Adviser may fail to produce the intended result. |
| Applied Finance Valuation Large Cap ETF | Large Cap Risk Member | |

| Risk [Text Block] | Large Cap Risk. Larger, more established companies may be unable to attain the high growth rates of successful, smaller companies during periods of economic expansion.
|
| Applied Finance Valuation Large Cap ETF | Risks Of Investment Selection Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Risks of Investment Selection. The Fund's investment success depends on the skill of the Adviser in evaluating, selecting, and monitoring the portfolio assets. If the Adviser's conclusions about growth rates or securities values are incorrect, the Fund may not perform as anticipated.
|
| Applied Finance Valuation Large Cap ETF | Risk Of Other Equity Securities Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Risk of Other Equity Securities. Other equity securities in which the Fund may invest include convertible securities, preferred securities, rights and warrants. Convertible Securities. Convertible securities are subject to the risks and price fluctuations of the underlying stock. They may be subject to the risk that the issuer will not be able to pay interest or dividends when due and their market value may change based on changes in the issuer’s credit rating or the market’s perception of the issuer’s creditworthiness. Some convertible preferred stocks have a conversion or call feature that allows the issuer to redeem the stock before the conversion date, which could diminish the potential for capital appreciation on the investment. Preferred Securities. The fixed dividend rate of preferred stocks may cause their prices to behave more like those of debt securities. If interest rates rise, the value of preferred stock having a fixed dividend rate tends to fall. Preferred stock generally ranks behind debt securities in claims for dividends and assets of the issuer in a liquidation or bankruptcy. Rights and Warrants. The price of a warrant does not necessarily move parallel to the price of the underlying security and is generally more volatile than that of the underlying security. Rights are similar to warrants, but normally have a shorter duration. The market for rights or warrants may be very limited and it may be difficult to sell them promptly at an acceptable price. Rights and warrants have no voting rights, receive no dividends and have no rights with respect to the assets of the issuer.
|
| Applied Finance Valuation Large Cap ETF | Sector Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sector Risk. Sector risk is the possibility that securities within the same group of industries will decline in price due to sector-specific market or economic developments. If the Fund invests more heavily in a sector, the value of its shares may be especially sensitive to factors and economic risks that specifically affect that sector. |
| Applied Finance Valuation Large Cap ETF | ETF Structure Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Structure Risk. The Fund is structured as an ETF and as a result is subject to special risks, including: •Trading Issues Risk. Although it is expected that shares of the Fund will remain listed for trading on NYSE Arca (the “Exchange”), trading in Fund shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund shares inadvisable, such as extraordinary market volatility. There can be no assurance that Fund shares will continue to meet the listing requirements of the Exchange or will trade with any volume. There is no guarantee that an active secondary market will develop for shares of the Fund. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund. This adverse effect on liquidity for the Fund’s shares in turn could lead to differences between the market price of the Fund’s shares and the underlying value of those Shares. •Market Price Variance Risk. The market prices of shares of the Fund will fluctuate in response to changes in the Fund’s net asset value (“NAV”) and supply and demand for Fund shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Fund shares may trade at a discount to NAV. The market price of Shares may deviate from the value of the Fund’s underlying portfolio holdings, particularly in times of market stress, with the result that investors may pay significantly more or receive significantly less than the underlying value of the shares of the Fund bought or sold. •Authorized Participants (“APs”), Market Makers, and Liquidity Providers Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. •Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.

| Applied Finance Valuation Large Cap ETF | ETF Structure Risk, Costs Of Buying Or Selling Shares Of The Fund Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Costs of Buying or Selling Shares of the Fund.

| Applied Finance Valuation Large Cap ETF | Mid And Small Capitalization Stock Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Mid and Small Capitalization Stock Risk. The value of mid and small capitalization company stocks may be subject to more abrupt or erratic market movements than those of larger, more established companies or the market averages in general.

| Applied Finance Valuation Large Cap ETF | Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Non-Diversification Risk. The Fund is a non-diversified portfolio, which means that it has the ability to take larger positions in a smaller number of securities than a portfolio that is "diversified." Non-diversification increases the risk that the value of the Fund could go down because of the poor performance of a single investment or limited number of investments.
|
| Applied Finance IVS US SMID ETF | Equity Securities Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Securities Risk. There is no guarantee that any favorable past performance of stocks selected for the Fund’s portfolio will continue, and such stocks may experience significant declines in value over short and longer time periods. Companies that issue these stocks may experience lower than expected returns or may experience negative growth, as well as increased leverage, resulting in lower than expected or negative returns to Fund shareholders. Many factors can affect a stock’s quality and performance, and the impact of these factors on a stock or its price can be difficult to predict. The Fund is subject to the risk that stock prices will fall over short or extended periods of time. Historically, the equity markets have moved in cycles, and the value of the Fund’s stocks may fluctuate from day to day. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments and adversely affect the Fund’s performance. The prices of stocks issued by such companies may suffer a decline in response. These factors contribute to price volatility, which is a principal risk of investing in the Fund.

| Prospectus [Line Items] | |
| Risk [Text Block] | Mid and Small Capitalization Stock Risk. The value of a mid and small capitalization company stocks may be subject to more abrupt or erratic market movements than those of larger, more established companies or the market averages in general. |
| Applied Finance IVS US SMID ETF | Market And Geopolitical Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market and Geopolitical Risk. Market risk includes the possibility that the Fund’s investments will decline in value because of a downturn in the stock market, reducing the value of individual companies’ stocks regardless of the success or failure of an individual company’s operations. The value of your investment in the Fund is based on the market prices of the securities the Fund holds. These prices change daily due to economic and other events that affect markets generally, as well as those that affect particular regions, countries, industries, companies or governments. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, pandemics, epidemics, terrorism, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years, such as terrorist attacks around the world, natural disasters, social and political discord or debt crises and downgrades, among others, may result in market volatility and may have long term effects on both the U.S. and global financial markets. There is a risk that you may lose money by investing in the Fund.
|
| Applied Finance IVS US SMID ETF | Foreign Securities Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Securities Risk. Investments in the securities of non-U.S. issuers involve risks beyond those associated with investments in U.S. securities. These additional risks include greater market volatility, the availability of less reliable financial information, higher transactional and custody costs, taxation by foreign governments, decreased market liquidity and political instability. Some countries and regions have experienced security concerns, war or threats of war and aggression, terrorism, economic uncertainty, natural and environmental disasters and/or systemic market dislocations that have led, and in the future may lead, to increased short-term market volatility and may have adverse long-term effects on the U.S. and world economies and markets generally. Foreign issuers are often subject to less stringent requirements regarding accounting, auditing, financial reporting and record keeping than are U.S. issuers, and therefore not all material information will be available. Securities exchanges or foreign governments may adopt rules or regulations that may negatively impact the Fund's ability to invest in foreign securities or may prevent the Fund from repatriating its investments. Less developed securities markets are more likely to experience problems with the clearing and settling of trades, as well as the holding of securities by local banks, agents and depositories. The less developed a country's securities market is, the greater the likelihood of custody problems. |
| Applied Finance IVS US SMID ETF | Depositary Receipts Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Depositary Receipts Risk. Depositary receipts are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted, including the risk that there is often less publicly available information about foreign issuers, and the possibility of negative governmental actions and of political and social unrest.
|
| Applied Finance IVS US SMID ETF | REITs Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | REITs Risk. Investing in REITs involves unique risks. When the Fund invests in REITs, it is subject to risks generally associated with investing in real estate. A REIT’s performance depends on the types and locations of the properties it owns, how well it manages those properties and cash flow. REITs may have limited financial resources, may trade less frequently and in limited volume, may engage in dilutive offerings, and may be subject to more abrupt or erratic price movements than the overall securities markets. |
| Applied Finance IVS US SMID ETF | Issuer Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.
|
| Applied Finance IVS US SMID ETF | Risk Of Other Equity Securities, Convertible Securities Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Convertible Securities. Convertible securities are subject to the risks and price fluctuations of the underlying stock.

| Applied Finance IVS US SMID ETF | ETF Risks Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Risks. The Fund is an exchange-traded fund, and, as a result of an ETF’s structure, it is exposed to the following risks: •Authorized Participants, Market Makers, and Liquidity Providers Limitation Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. •Cash Redemption Risk. From time to time, the Fund may redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. •Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments. •Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV. •Trading. Although Shares are listed for trading on a national securities exchange, and may be traded on other U.S. exchanges, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares.

| Applied Finance IVS US SMID ETF | New Fund Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | New Fund Risk. As of the date of this prospectus, the Fund has less than a year of operations and currently has fewer assets than larger funds. Like other new funds, large inflows and outflows may impact the Fund’s market exposure for limited periods of time. This impact may be positive or negative, depending on the direction of market movement during the period affected.

| Applied Finance IVS US SMID ETF | Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Non-Diversification Risk. The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political or regulatory occurrence than a diversified fund. |

The less developed a country's securities market is, the greater the likelihood of custody problems. |

| Risk [Text Block] | Depositary Receipts Risk. Depositary receipts are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted, including the risk that there is often less publicly available information about foreign issuers, and the possibility of negative governmental actions and of political and social unrest. |

| Risk [Text Block] | REITs Risk. Investing in REITs involves unique risks. When the Fund invests in REITs, it is subject to risks generally associated with investing in real estate. A REIT’s performance depends on the types and locations of the properties it owns, how well it manages those properties and cash flow. REITs may have limited financial resources, may trade less frequently and in limited volume, may engage in dilutive offerings, and may be subject to more abrupt or erratic price movements than the overall securities markets.

|
| Applied Finance IVS International Large ETF | Risk Of Other Equity Securities, Convertible Securities Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Convertible Securities. Convertible securities are subject to the risks and price fluctuations of the underlying stock. They may be subject to the risk that the issuer will not be able to pay interest or dividends when due and their market value may change based on changes in the issuer’s credit rating or the market’s perception of the issuer’s creditworthiness. Some convertible preferred stocks have a conversion or call feature that allows the issuer to redeem the stock before the conversion date, which could diminish the potential for capital appreciation on the investment. |
| Applied Finance IVS International Large ETF | Risk Of Other Equity Securities, Preferred Securities Member | |

| Risk [Text Block] | Preferred Securities. The fixed dividend rate of preferred stocks may cause their prices to behave more like those of debt securities. If interest rates rise, the value of preferred stock having a fixed dividend rate tends to fall. Preferred stock generally ranks behind debt securities in claims for dividends and assets of the issuer in a liquidation or bankruptcy. |

| Risk [Text Block] | Rights and Warrants. The price of a warrant does not necessarily move parallel to the price of the underlying security and is generally more volatile than that of the underlying security. Rights are similar to warrants, but normally have a shorter duration. The market for rights or warrants may be very limited and it may be difficult to sell them promptly at an acceptable price. Rights and warrants have no voting rights, receive no dividends and have no rights with respect to the assets of the issuer. |
| Applied Finance IVS International Large ETF | ETF Risks Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Risks. The Fund is an exchange-traded fund, and, as a result of an ETF’s structure, it is exposed to the following risks: •Authorized Participants, Market Makers, and Liquidity Providers Limitation Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. •Cash Redemption Risk. From time to time, the Fund may redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. •Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments. •Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV. •Trading. Although Shares are listed for trading on a national securities exchange, and may be traded on other U.S. exchanges, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares.

| Prospectus [Line Items] | |
| Risk [Text Block] | New Fund Risk. As of the date of this prospectus, the Fund has less than a year of operations and currently has fewer assets than larger funds. Like other new funds, large inflows and outflows may impact the Fund’s market exposure for limited periods of time. This impact may be positive or negative, depending on the direction of market movement during the period affected.

|
| Applied Finance IVS International Large ETF | Foreign Currency Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Currency Risk. Although the Fund will report its NAV and pay dividends in U.S. dollars, foreign securities often are purchased with and make any dividend and interest payments in foreign currencies. Therefore, the Fund’s NAV could decline solely as a result of changes in the exchange rates between foreign currencies and the U.S. dollar, particularly if the Fund invests a significant percentage of its assets in foreign securities or other assets denominated in currencies not tightly pegged to the U.S.

| Applied Finance IVS International Large ETF | Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Non-Diversification Risk. The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended. This means it has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty and make the Fund more susceptible to risks associated with a single economic, political or regulatory occurrence than a diversified fund.
|
| Applied Finance IVS International SMID ETF | Equity Securities Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Securities Risk. There is no guarantee that any favorable past performance of stocks selected for the Fund’s portfolio will continue, and such stocks may experience significant declines in value over short and longer time periods. Companies that issue these stocks may experience lower than expected returns or may experience negative growth, as well as increased leverage, resulting in lower than expected or negative returns to Fund shareholders. Many factors can affect a stock’s quality and performance, and the impact of these factors on a stock or its price can be difficult to predict. The Fund is subject to the risk that stock prices will fall over short or extended periods of time. Historically, the equity markets have moved in cycles, and the value of the Fund’s stocks may fluctuate from day to day. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments and adversely affect the Fund’s performance. The prices of stocks issued by such companies may suffer a decline in response. These factors contribute to price volatility, which is a principal risk of investing in the Fund.

| Applied Finance IVS International SMID ETF | Risks Of Investment Selection Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Risks of Investment Selection. The Fund's investment success depends on the skill of the Adviser in evaluating, selecting, and monitoring the portfolio assets. If the Adviser's conclusions about growth rates or securities values are incorrect, the Fund may not perform as anticipated.
|
| Applied Finance IVS International SMID ETF | Risk Of Other Equity Securities Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Risk of Other Equity Securities. Other equity securities in which the Fund may invest include convertible securities, preferred securities, rights and warrants. •Convertible Securities. Convertible securities are subject to the risks and price fluctuations of the underlying stock. They may be subject to the risk that the issuer will not be able to pay interest or dividends when due and their market value may change based on changes in the issuer’s credit rating or the market’s perception of the issuer’s creditworthiness. Some convertible preferred stocks have a conversion or call feature that allows the issuer to redeem the stock before the conversion date, which could diminish the potential for capital appreciation on the investment. •Preferred Securities. The fixed dividend rate of preferred stocks may cause their prices to behave more like those of debt securities. If interest rates rise, the value of preferred stock having a fixed dividend rate tends to fall. Preferred stock generally ranks behind debt securities in claims for dividends and assets of the issuer in a liquidation or bankruptcy. •Rights and Warrants.

|
| Applied Finance IVS International SMID ETF | Market And Geopolitical Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market and Geopolitical Risk. Market risk includes the possibility that the Fund’s investments will decline in value because of a downturn in the stock market, reducing the value of individual companies’ stocks regardless of the success or failure of an individual company’s operations. The value of your investment in the Fund is based on the market prices of the securities the Fund holds. These prices change daily due to economic and other events that affect markets generally, as well as those that affect particular regions, countries, industries, companies or governments. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, pandemics, epidemics, terrorism, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years, such as terrorist attacks around the world, natural disasters, social and political discord or debt crises and downgrades, among others, may result in market volatility and may have long term effects on both the U.S. and global financial markets. There is a risk that you may lose money by investing in the Fund.

| Applied Finance IVS International SMID ETF | Foreign Securities Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Securities Risk. Investments in the securities of non-U.S. issuers involve risks beyond those associated with investments in U.S. securities. These additional risks include greater market volatility, the availability of less reliable financial information, higher transactional and custody costs, taxation by foreign governments, decreased market liquidity and political instability. Some countries and regions have experienced security concerns, war or threats of war and aggression, terrorism, economic uncertainty, natural and environmental disasters and/or systemic market dislocations that have led, and in the future may lead, to increased short-term market volatility and may have adverse long-term effects on the U.S. and world economies and markets generally. Foreign issuers are often subject to less stringent requirements regarding accounting, auditing, financial reporting and record keeping than are U.S. issuers, and therefore not all material information will be available. Securities exchanges or foreign governments may adopt rules or regulations that may negatively impact the Fund's ability to invest in foreign securities or may prevent the Fund from repatriating its investments. Less developed securities markets are more likely to experience problems with the clearing and settling of trades, as well as the holding of securities by local banks, agents and depositories. The less developed a country's securities market is, the greater the likelihood of custody problems. |
