I'd put 200 on red. Oh wait. I've been actually wanting to do this too, but the one thing that is stopping me is the limit on trades to low balance accounts. I want to be able to diversify and then bail out of all my positions in the middle of the day if I get a whiff of something bad coming.
From what I understand, margin account require a 25k balance at all times to be able to have unlimited day trades. eesh..
I always go black .
