That's hard to answer. I trade Forex not options so i have huge leverage 50/1 but I'd only use about 20/1 of it. Starting out small with 0.06 lots, 40/60 pips per trade and around 350 trades a year per fx pair. It depends on the market really.
1. Are you 100% sure your account would increase and not decrease?
2. Would it be less than $500,000?
