I Believe I'm confused... I am Certain you are trying to show me the logic of how that will fit into this Scenario:

I've a micro lot account

I could Possibly have a number of trades Available from multiple EAs and a number of currencies

what I do Not want to Occur is a margin call even when all trades stop out

I have a demo account that I started at 10k... That I will probably start with 5k when I go live
