How can i refer to the symbol, the time frame and the spread in the MT4 strategy tester in mql4 code ?

 

Hello everybody,

I'm developing a tool to backtest my EA and I want to change the symbol, the time frame and the spread in the MT4 strategy tester automatically by mql4 code.
How can i refer to the symbol, the time frame and the spread in the MT4 strategy tester in mql4 code ?
Thank for your idea.

Can't be done. You can only trade the current symbol. You can refer to whatever timeframes you want. Spread is independent of TF.
