Code2219 or probably 2319:
Hi, in tester (No visualization) that nested if is always true. (since Hcopied+Lcopied+Ocopied+Ccopied always = -4)
So, Copy functions always return -1;
WHY ?
these whole code is inside OnTick(), the EA is works in multi-TF , if that matters.
Also, where can i see the journal (where all EA logs are printed to) in Visualization mode ?
Do I need to disable fail checks of Copy functions, for backtesting ?
You ALWAYS need to check for errors. Copyxxx function returns an error only if value is -1, it could also return "4" even if you asked 5 values. What is the error code returned ?

thanks to mention the error code, it was my mistake. (didn't resize my target array before copy, so my target was smaller than requested number of values.)You ALWAYS need to check for errors.
