I'd advise trading the big contract, so CL over QM. If your risk management is good, you shouldn't have a problem. I've recently started day trading CL, YM, NQ, ES, and some of the forex markets all based on technicals. It's been interesting and I am consistently learning, but the best way to learn is by being in the game with real cash.
