| Material Fund Change [Text Block] | How has the Fund changed? Effective July 1, 2024, the Fund's name, investment objective, and principal investment strategy changed. The Fund is no longer an “index fund” that seeks to track the performance of its benchmark index and instead is managed using an “active” investment strategy, process and approach. Accordingly, the name of the Fund changed to “BNY Mellon High Yield ETF”. The Fund seeks total return consisting of capital appreciation and income. The Fund seeks to provide diversified investment exposure to the U.S. high yield bond market. While the Fund is not an index fund and does not attempt to replicate any index, the Fund normally invests substantially all of its assets in bonds that, at the time of purchase, are included in the Bloomberg U.S. Corporate High Yield Total Return Index, ETFs providing exposure to securities included in the Index and derivatives with economic characteristics similar to such bonds, ETFs or the Index. This is a summary of certain changes to the Fund since November 1, 2023.
