I've found emotions play a very large part in trading, maybe 60%. Then risk management. The technical aspect is really a small part, but important part. Once you master a strategy like yours it's all about limiting your losses and letting your winners run. Earlier on I use to keep my stops a little to tight, might get a point on a 3 or 4 point move. Scaling out helped with my emotions, along w/ lot sizes after scoring the probablites of the trade.

Ken, How do you keep your emotions in check?
