Traders might be outspoken or intraverted, they may be silent in a party while the other type of them might be very shining.
But a good one will always have the following I THINK:
1. great confidence of self-judgement. Believe themselves can see something more clearly than most of the ppl in the market. and During cases when market moving not in their favor, they can still stay on, of coz, before their stop loss line was touched.
2. extreme discipline. If they have 1 but do not have point 2. they will probably end up with losing all the wealth. because they might just do not believe they are wrong in some big positions and refuse to cut loss despite of well-set stop loss line, then all finish.
3. Intelligent. Of coz, this is required by most of the careers. including science and engineering and IT etc
4. have clear goals.
5. can handle tough situations in life well. This is a general characteristic of ppl having high EQ :)
just think of these points. welcome all experts here to add on. :) nice after-lunch discussion anyway.
Talk is cheap. the above points look easy, but when you are in the situation, you might just lose yourself.
Just imagine, will you having lunch and rest well and work as normal if you have a losing position of a few million dollars and probably boss is shouting at you? :)
Not only trader, most of the careers require these if you want to be excellent in them. Trader also got losers. hehe...
