Guys - I think the concept of the three trader types is really important to understand. Moreover, I don't think it's possible to generalize as Dr. Ken did about 90% of the Type 1 traders losing their accounts. I witnessed a Type 3 trader blow-up in a unforgettable fashion.
It's really important to be able to catch oneself "freezing" or "day-dreaming" or "going into a state of confusion" while in a trade. Been there, done that....I know what he was talking about.
