I think previous occupations (or hobbies) where pure logic without emotion would help more than anything else. Logic, reasoning and a creative flair. The ability to look at something and deduce a pattern. Formulate hypothesis and test them. Construct trading systems etc.
So I would say people from a scientific, engineering background would be more attracted, and possibly successful at trading. They are use to using their minds rather than their instinct, but are still able to creatively form new ideas.
The other trait which I think is very important is the ability to understand the human psyche. As the market is nothing but a bunch of humans in a crowd. If you understand how the human mind works as an individual and in a crowd, you will be a good way towards understanding the market too.
There is no coincidence then that there are a high number of software engineers in to trading, and there are a disproportionate number of traders involved in psychology/psychotherapy.
