#1 Always use a stop loss Even if you don't like to use a stop loss you need to use a catastrophic stop loss. #2 Always be aware of news/number releases and never have an open position going into any such release. If you don't believe me just look at market action in ZB on 3/18 and NG on 3/19 - a $7,000 move per contract in seconds. That's an INSTANT BLOWUP if you use max leverage and you're on the wrong side. Its also INSTANT HOMELESSNESS.
