| Performance Narrative [Text Block] | The performance information presented below provides some indication of the risks of investing in the Fund by showing the extent to which the Fund’s performance can change from year to year and over time. The bar chart below shows the Fund’s performance for the most recent calendar years ended December 31. The table illustrates how the Fund’s average annual returns for the 1-year, 5-year, and since inception periods compare with those of the Solactive GBS Global Markets All Cap USD Index TR, a broad-based securities market index intended to represent the overall global equity market. The table also shows how the Fund’s performance compares to the Roundhill Video Games Blended Index, which represents the underlying indexes tracked by the Fund from inception until September 30, 2025. The Fund’s investment objective and principal investment strategies changed on September 30, 2025, when the Fund converted from a passively-managed index fund into an actively managed fund. Prior to that date and beginning September 26, 2022, the Fund sought to track the performance, before fees and expenses, of the Nasdaq CTA Global Video Games Software Index™. Prior to September 26, 2022, the Fund sought to track the total return performance, before fees and expenses, of the Roundhill BITKRAFT Esports Index. Therefore, the performance and average annual total returns shown for periods prior to September 30, 2025 may have differed had the Fund’s current investment objective and principal investment strategies been in effect during those periods. The Fund’s past performance, before and after taxes, does not necessarily indicate how it will perform in the future. Updated performance information is available on the Fund’s website at www.roundhillinvestments.com/etf/NERD.
