Well, I've catalogued a few point that I think are common amongst successful traders and I find that a part of me because I've also been trading for the past 28 months and have been quite successful:
1. discipline: the ability to recognise when a trade is wrong and therefore minimise losses.
2. Risk control: having a strong understanding of a trade's risk/reward.
3. Courage: the willingness to be different from the rest of the crowd, most of the time.
4. Right judgements: judging how perceptions are shaping market trends.
