Scalper. I love swimming with the prevailing current, skimming a few points off the top, and then moving onto the next play. I'm comfortable with large lots on margin, and I limit my risk exposure by setting rather tight stop losses, which range from 3-5%.
I will swing when I see conditions are right. For example, crude oil / oil service plays have been hot for the last week; I've swung these based on the trade thesis that oil was 'dumb cheap' in the 30s. Also, I suspected there would be some upside price correction that would carry through for a few days. When the bull market returns, I will probably revert back to being more of a swing trader.
