Assume that You log in your account on 2 terminals and run your EA on both terminals (at the same time)
What will happen then ? EA execution duplicated ? 
And what if you run 2 EAs on 2 terminals with ONE account ?
I don't have the second terminal to test the case. So please do not complain me about posting this query here.
