Problem in list backtest

My list of backtest is duplicate !
Does anyone know what the problem is?



Hard to say without seeing your code, but did you attempt to write your own CBT and call the bo.ListTrades() method? Here's an excerpt from the documentation at

(Version 4.68.0 and above) This outputs trades to the result list of Automatic Analysis window. Usually this function does NOT need to be called because Backtest() method by default lists trades already. This function should only be used when you disabled trade listing in Backtest method to add some custom per-trade metrics.
