You can't trade 10 ES @ 300 margins with only 3k on deposit.$300 margin. That is serious over leveraging. If you account was $3000 and you traded 10 contracts of ES using the full margin it would only take 24 ticks to wipe out your account lol. The ES can move 24 ticks in a heartbeat if there is unscheduled news, which is a certainty if you trade for any period of time. $300 margin on ES, suicidal imo.
