Made some practical tests on the fee cost issue when copying large amounts. Since many simulation platforms do not include fee calculations, I ran a dedicated simulator with the data. Currently, it is the 1st day, and the total return is close to 3%, but today’s market data has not been fully incorporated into the statistics yet. The main purpose of this experiment is to see how the actual returns of the copy trading strategy perform under continuous fee deductions. @BTC@ and @JELLYJELLY@ are within the observation range. Subsequent updates will include complete 24-hour data feedback, which should be helpful for friends who want to understand the real costs.
