What you should really be worried about is when you have a stop set, then some fat fingered SOB puts in an order 10 pts away, which triggers your stop. It hasn't happened in awhile, but it will. That's one reason I never set a hard stop. I always use a mental stop. Most traders blow out in futures because they use the leverage. You should limit your leverage based on your account and tolerance for risk, not on the broker/exchange requirement. A an example, on the ES I use a minimum of $10,000 per contract intraday. For overnight I use $40,000 per contract.
