I think i should not put this thread in psychology, because Ego is not psychology. but ego creates emotions, like sadness, frustration,anger, joy,... first I need say I have a strong ego. that hurts me. I often find myself to argue with the market, or fight with the market,t.... when i win, i feel i defeat the market, when I lose, I feel I am attacked by the mean market.... that hurts my trading. I just listed an example in another thread trading management. I was trading natural gas, I saw it was in down trend, so it is wise to short. unfortunately I was stopped out. then late it started to drop just as I believed. or just drop to my target, I shorted it again, it seems to tell the market:yes, I am right. but it bounces, so I cut loss again. the results is I dig deeper a hole in my account. am i stupid? in hindsight, I know I did stupid thing. any good suggestions about ego control.
