I am getting an error 131 on build 880 when I try to do backtest offline. How can I solve this problem, which occurs only on few markets, not all?
Thank you in advance.
Don`t say things you are not sure about!
Actually my code in not broken because I have done many, many backtests without any errors on the previous builds.
from what i read regarding 880, the problems you are facing may have to do with imported chart data or maybe with the fact that you have not logged in online on the given terminal . On top of the forum there is a discusssion regarding the 880 release and it is possible that you find there more information
You do not need to downgrade, just add the executable:
Now you should have additional launching alias icon dedicated for testing strategies in disconnected mode (though you cannot run them both concurrently).
