when starting the "Strategy Testing" then the above error message is shown. When taking a look to the path:
The files to be opened seems to be deleted by "someone". When I copy them by hand into this directory and then starting the Strategy testing the files are gone and the above error message is shown.
When starting "Live" Mode or Debugging - the error is not shown.
Do you have an idea?
Have you specified property "tester_file" in your program (https://www.mql5.com/en/docs/basis/preprosessor/compilation)?
Could you write to servicedesk and provide source of your EA?
I don´t think that code is necessary as it is like "zephyrr" wrote earlier:
"I found the same error after update to the new version of build 540. also, i found that after start the strategy tester, the tester delete all the files in the tester mql file directory, such as " c:\Programme\Metatrader 5\tester\agent-127.0.0.1-3000\mql5\files\". I have found no solution yet and can only wait for the new update to solve the problem."
All the files are being deleted when starting the "Strategy Tester". Pls - if you copy files in the above mentioned path they will be deleted. So very easy to reproduce the behavior!
Can I downgrade to Buil "53x" as the code worked fine in the past?
Could you pls send me the email/Link of the Service Desk?
could you pls send me the contact data for the servicedesk?
I contacted the Service Desk! As it will take some time to solve the issue - maybe with the next Build!? Last question on that: Can I install an older version - so BUILD 5XY ? - and i f yes: Where to download?
hi guys, is there any update regarding this subject ? having the same issue here.
Just add (it works!):
#property tester_file "name of the file.txt" to your EA somewhere at the beginning.
If you do it the file will be copied from your "normal" location (used by Indicators/EAs) to the testers subdirectory.
