If the data are different in the Strategy Tester, for any reason, the code should be able to manage it.
So...fix the code.
Look up your error codes here
Fairly self-explanatory. Good job you don't see it in live trading then...
Unusual for strategy tester. Are you using tick data?
i been running EA testers fine until update 1045.
guess what - now im getting error 138 + 130.
its not the code that needs to be fixing. its update - that broke the codes..
But I normally find it better to presume the problem is with my code rather than the build.
Are you using 3rd party tick data?
no. just 1 minute data used.
was running tests fine until closed mt4 -> update -> loads of errors :(
