Backtesting OK buy No trades when Optimization is on

 

Hi

 I have an EA which I am able to backtest and it does trading on backtest

 However, when I turn on "Optimization" using the same settings on "value", "start" and "stop" with one variable to be step, the ea does not trade at all on all optimization passes.

 Does anyone know what is the likely cause of this to happen?

 

Thank you

 
You can check which passes failed and run just those passes using those input variables and see the error in the log file.
