...well, doc, it may have been a grand question but you cut it down to size. I think Larry Pesavento was the first to say "You're not looking in a monitor, you're looking in a mirror." I agree with you that Mark Douglas has the problem nailed. In addition I like Dr. Elder's perspective relating trading behavior to addictive behavior. I don't think Jung would be displeased if we adapted his "All psychology is autobiography" to "All trading is autobiography".
Did your achievement of psychological distance from the market just happen to coincide with profitability (haha)? In my own case I have practiced insight meditation for some time, but its deliberately calm circumstances did not prepare me for the upwelling of bizarre ideation which appeared under the pressure of discretionary trading. I had to switch to rigid system trading to have any hope of succeeding. If I may ask, where do you come down on the question of discretionary vs. mechanical? Thanks for replying, and have a good evening.
