Hey Mr. Tools I have a MT5 EA that does not work in the Strategy tester properly. After doing some research it seems to be that I don't have "error testing" in my EA therefore when I test it sometimes it comes back with no results. I also get a "wrong timeframe request in open prices mode" but it doesn't work in any mode. So places say that I need code like this everywhere but i'm not sure.

if(CopyOpen("EURUSD",Inp_timeframe,0,1,buffer_1)!=1)
Print("CopyOpen Error : ",_LastError);

Thanks for any help.
