Its weird, when Im trying this EA with another MT4 on the same broker it doesnt shown that error. Then i try to attach on another broker it doesnt shows error.

But when i use this EA on MT4 that i use to use this EA (with previous verison of this EA) it always shows errors. 

FYI i have 3 MT4 on same broker with this EA on previous version. ALL MT4 shows errors.

ANother MT4 dont use EA, when i use this EA it fine


is that weird?

 
  1. Use the debugger or print out your variables, including _LastError and prices and find out why. Do you really expect us to debug your code for you?

  2. Martingale, guaranteed to blow your account eventually. If it's not profitable without, it is definitely not profitable with.
