I am a new trader who has come up with a trading strategy to go short and long on a forex on the weekend before the market closes. Besically me and my friend have 2 accounts so one of us would go short and one would go long at the same time just few seconds thr market closes, using 400 to 1 leverage we hope that on monday when the market opens it would go - or + above 0.27% and thats how we make our profit, the policy of this broker is no negative account balance so we are protected, i just wanted to know is this against most brokers policy? thank you for your help.
