| Performance Narrative [Text Block] | The following performance information indicates some of the risks of investing in the Fund. The bar chart shows the Fund’s performance for each calendar year 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 a broad measure of market performance. 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.acquirersfund.com. Prior to December 7, 2021, the Fund operated as an index-based ETF that sought to track the performance of the Acquirer’s Index. Consequently, performance for periods prior to December 7, 2021 does not reflect the Fund’s current investment strategy as an actively-managed ETF. The Fund’s performance may have differed if the Fund’s current strategy had been in place.
