| 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 as of December 31. The table illustrates how the Fund’s average annual returns for the 1-year and since inception periods compare with a broad measure of market performance and the index the Fund seeks to track, in that order. Effective June 6, 2025, the Underlying Index implemented a change to its rules-based methodology, which resulted in corresponding changes to the Fund’s principal investment strategy (the “Repositioning”). In connection with the Repositioning, the Fund transitioned from a tactical high yield bond strategy, which previously allocated between high yield bond ETFs and intermediate U.S. Treasury ETFs, to a tactical intermediate core-plus bond strategy that employs a trend-following system. Accordingly, performance of the Fund and Underlying Index shown prior to June 6, 2025 reflects the Fund’s and Underlying Index’s prior principal investment strategy and methodology, respectively; the Fund’s and Underlying Index’s performance would have differed if the Fund’s and Underlying Index’s current principal investment strategy and methodology, respectively, had been in place. The Fund’s past performance, before and after taxes, does not necessarily indicate how it will perform in the future. Updated performance information is also available on the Fund’s website at www.abacusfcf.com.
