I'm done, I have spent three days on this error and at this point I'm pretty sure that my robot doesn't have any problem
it prints massages about:
the problem is no trade operation has no meaning there is no error number to check I don't know what to look for is it my problem or is it the validation test's problem
last day I passed the check for my indicator with no problem it's just the EA
this guy says he has tried 20 times for passing the check
