Most traders here -- that is, intraday, short-term, tape readers etc -- would probably agree with the following: "You don't have to know what's going to happen next in order to make money." (Mark Douglas) Although I agree with this statement, I think it's somewhat misleading on its own, and would add the following emphasis: "You shouldn't know (or even want to know) what's going to happen next, in order to maximize your profits." In other words, in order to maximize one's trading results, one must suppress the instinctive need for certainty, while embracing uncertainty. Thoughts?
