Most likely blow out the first account?? It's a near certainty. Why? Not because of anything to do with the OP, but because that's what we do, as humans do first. Our hubris is unbounded. If you're lucky, you'll put that in check after the first blowout. There are still times when I feel, "I can totally play this market like a harp," and that is quickly followed by, "Boy, I'm screwed. Lower my risk immediately." That's when the big old ram in the a$$ happens. I'm not sure this ever goes away.

As for the safest contracts to trade... YM, and ZB is prob the safest. It'll put you to sleep, but there's money to be made.
