{quote} ok, but even with 30% stopout level you shoud have an margin call. you are with your 4 lot open and account big enough for 2,2 lot trades by under 20% , so 30% stopout level is already reached without any problem.
I deposit 500... leverage is 500, so one lot would require 200 margin.
2 lot buy opened, used margin =400
2lot sold, used margin 0
2 lot buy, used margin 400
equity now about 450 since comission and spread are paid
2 lot sell closed, used margin now 800 equity 450 and that is not even near 20%-30%... it is actually over 50%... trade may go against you until equity is 240 (30%of 800)..
