Rosh:
1. No, Expert Advisor can operate only on the one account. If you select "Disable experts when the account has been changed" and change account then attached to chart EA (Expert Advisor) will be deinited and stopped.
The strangeness (wonderful thing :) ) happened in my MT4 terminal (build 211)
When I select the option : "Disable experts when the account has been changed"
Now !
Two EAs are operating in deferent accounts simultaneously !
