Quote from doublef:
you are very smart and think very hard, I think you must work very hard too.
you have spent a lot of time on things that are related to trading, but not essential to trading. it is natural because you approach trading from a distance and come across many interesting things as you get closer to the gist of trading.
as time goes by, you will get rid of those things that are not essential to trading (some of them are plain wrong, but we didn't know when we started, we probably thought they were good stuff, occasionally we might mistake them for holy grails...).
it is not necessary to know the reasons of trading failure, a trader can make a profit without knowing them. the trader is like a monkey that is thrown into a metal cage. when an electric current is sent through the metal cage, the monkey will jump around until it lands on a rubber mat at the corner of cage, that is when the monkey successfuly avoids electric shocks, the monkey doesn't know rubber is a kind of material that insulates it from electricity, it only knows that if he stands on that black rubber mat instead of the metal floor, it won't feel any pain.
