Quote from illiquid:
IMO, pride is the source of just about all of the psychological pain you place on yourself while trading -- from not getting out of a losing trade to beating yourself up for not taking the most out of a winning trade -- it's all due to ego. There's a fine line between "motivation" and "revenge-seeking", and it all comes down to how one deals with the ups and downs of the profession. And don't get me wrong and think I'm lecturing -- I know exactly where your coming from.
But overall its hard to say whether good trading should be comfortable/boring/exciting. For me, it's when my trading becomes most comfortable and satisfying that I need to be most careful, and that a big drawdown just might be around the corner. The dissatisfactions, pains, and sufferings keep me on edge, and those I'll gladly take in place of a bottom line loss anyday. Perhaps I'll never truly ever be satisfied and comfortable while I trade for a living, but if that's the case it wouldn't surprise me.
of course..that's not the "not cutting losses and admitting you are wrong " pride..but about winning in a game where 95% of people loses ..it's about the pride of being doing something other people can't do..
The problem is the dissatisfactions, pains, and sufferings when you down doesn't balance out with the joy, eurphoria and rush when you are winning...as you yourself said, when my trading becomes most comfortable and satisfying, something is WRONG..
and I think most pro traders have condition themselve NOT to dwell on the comfortable and satisfying emotions..I don't even feel too excited when I am up 150k a day... on the other hand, I don't feel too bad when I down 30k too..anymore than that, I start to feel the pain...
so it is not symmetrical, and trading ends up a emotionally negative sum game..
