Thank you for your explanation, Petra.

Now I see these 'not found' messages are explained in the manual, so I will make some notes!

As for this 013 error message, it isn't causing a crash in my script itself. As stated, it only happens in TRADEMODE during the beginning of a session, right after a data pre-fetch procedure in my script, that runs fine. There's no message in my .log file, but only in Zorro's output window:



Maybe this in an internal bug in the MT4 plug-in? I'm using version 4.24.

I will test this as well in a Windows environment. If I can reproduce this error with a sample script, then I can provide it to support when needed.
