If I have 2 MT4 with 2 different account but same EA do I need 2 magic number? The title says it all, I have 2 MT4 terminal opened at the same time but each one on a different account, but I have the same EA running on each one of them, do I need to change magic number on one of them, or it doesn't matter because they running on different terminal. 44 Apr 06 at 19:33
