now i know, maybe it like 2 step confirmation, first it calculate all mt4 ( 4 mt4 ) if reach target it look again where mt4 reach target and close that. This cannot separate account if separate account every ea DD very high, use lot 0.1 like superarrowsbb80 it touch flooting 1k4, superarrowsbb40 it flooting 800, mabb3 flooting 500, tamerhassan 600. but if i put together at one account all flooting just touch 500usd, it will open so much position and it will give we large rebate.Maybe you open too many charts and once EA send close order but it has time delay because you open so many charts and sometimes fails to close all??
It is better if you can separate account for each EA.
