because people, like myself also, are impatient, greed takes over, and that s when u fail. specially if u have a higher win rate, ur ego get s so large that u can t accept not being right, so u hold onto ur losers till they turn into massive holes in the account. that s what happened to me atleast not so long ago. had to take a step back and realise that wasn t my analysis or my entry techniques, but my ego and the greed that comes with it. was harder for me to teach myself to take the losses fast without thinking to much than to learn how to trade.
