Do I have a problem with my Strategy Tester, or is it the normal way of running Strategy Tester? No Displays in Experts Windows, and no files created.
Hello Pierre have you looked at the GetLastError() yet ?
int h=FileOpen("Start eaStrategyTester.txt",FILE_WRITE|FILE_ANSI|FILE_TXT); if(h==INVALID_HANDLE) { Alert("Error opening file ", GetLastError()); return(INIT_FAILED); }

Hello Marco vd Heijden,
Thanks for your help.
I changed my EA :

If I run my EA with the Strategy Tester no Windows Alert, nothing in the Experts windows, no files created.
If I read the Log file all things seen OK.
That will not work you essentially have these lines outside of the logic they will always print that message regardless of the return value of the function.

If you read the documentation it states:
The file is opened in the folder of the client terminal in the subfolder MQL5\files (or testing_agent_directory\MQL5\files in case of testing).
Make sure you have that directory correct.
It could be there all along.
Thanks Marco.

Hello,
Do I have a problem with my Strategy Tester, or is it the normal way of running Strategy Tester?
My EA :
If I normally run my EA it will write in the Experts window and will create the files.

Is this the normal function of Strategy Tester?
Thanks in advance,
