I've been up to this recently. None of the maths I've used is very advanced yet. I've mostly been trying to use simple statistical tools like regression analysis as well as possible. I know a few people who have found employed in finance after having done graduate work in stochastic processes, but I'm not sure what the payoff would be for some of the more advanced stuff as a non-institutional trader.
