When my same EA ran EventSetMillisecondTimer(50) within OnInit() on 4 charts, it returns successful on 1 chart only, wrong code is " Internal error"(translated to the description) on all other 3 charts.
Why did it happen? How to prevent or fix the issue? Thanks.
I agree, more likely it is a bug. As a workaround, for the time-being, you may make some copies of the EA with different names and tell us what happens.
