This is what it looks like when you just need to delete the Expert Advisor when you change the account.
The simplest task in MQL5 will make you dance the subversion.
It is not always possible to delete an EA when changing an account.
Suppose the EA has been run on EURUSD symbol. It will switch to the server where symbols are prefixed. For example, EURUSD.abc.
In this case, the EA still hangs and cannot delete itself. Does anybody have a solution to this problem?

The solution couldn't be simpler, just work with the string and extract just the right part from there.
Please show here the source code of the EA that unloads itself when the account is changed.

I understand that it should be unloaded to init (or better to ontik) after the change. I.e. to remember in global variables account numbers and if change occurs, then unload. You can also try to analyze _DeInitReason in init() and unload.

in this case OnInit() is not started? maybe at the level of OnDeinit() try to remove?
