Error: Tester - debug version of "Advisors\EA.ex5" detected

New comment
 

Hi all.

I am migrating my EAs from MT4 to MT5. Yesterday I ran some back testing and worked fine. Today I get this error. and MT5 won't let me run optimizations.

Says:

- debug version of "Advisors\EA.ex5" detected

- optimization cannot be started

Thank you in advance for your time.

You need to compile the Expert Advisor and then you can immediately start optimization.

I did that.

I use F7 (compile) and I get the same error as when I do profile on history data. No difference.

On the Strategy Tester I also tried to select another EA (not the one I am working on ) and I get the same errors.

You have to compile and then run the optimization right away.

Close the visual tester window. Then compile the advisor. After compilation, you can optimize.

 

I closed MetaEditor, MT5, everything.

Reloaded, compiled, and backtest works now.

Thank you for your help, mate!

Cheers!

 

Here's an example: I started debugging on history. After that, I ran the optimization - a warning appeared:

 2021.12 . 01 18 : 37 : 00.423 Tester  debug version of "MyExp\EA.ex5" detected
 2021.12 . 01 18 : 37 : 00.450 Tester  debug version of "MQL5\Experts\MyExp\EA.ex5" can be optimized on local agents only, no Cloud, no Farm

this way I can optimize, but only on my PC.


After that, I stopped the tester and compiled the EA. Now I run the optimization again and ... now there is no error!

 

I see.

Will keep that in mind in case I come across this issue again.

 
Please tell me EXACTLY which 2 checks are failing. I have fixed all 15 standard checks but validator still shows 2 errors without details

Yeah, that's normal behavior in the terminal. A debug version of the EA has extra info for step-by-step debugging, so it can only run on local agents. Cloud and farm agents don't support those builds. Once you compile it in the regular (release) mode, the restriction goes away and optimization works on all agents again. Just make sure you switch the build before running in the cloud.
