Hello,

I have an EA that works very well on real/demo account but on Strategy Tester gives error 4806 on if(CopyBuffer()...) test.

Any suggestions?

Thanks in advance !

Strategy tester works on historical data right ? In some case it can't get the data so you have to download it. It's difficult to say which data and how as you don't show your code (CopyBuffer for what ?).

You can force the download manually or by code.
