Good money management technique will be to set targets, and withdraw to secure capital just in case of the worst.
Start with 3500. Maybe have a target of 15k or even 30k. When you reach your target take out 5 - 10k and place it in a savings account or somewhere save to sit back on. build up to another target maybe 50k or so, take out some more and place it somewhere safe.
I learned this method of money management from a high level investor who's made millions in the market. It's common sense. But it's pure genius. SECURE YOUR MONEY! Just a thought buddy. I'm 19, started at 18 and have just over $100k starting with $12k. I run mainly credit spreads, and occasionally I'll run a few calls, and puts for large gains.
Keep up the good work. Just thought I could help you organize your money management. I'd hate to see you lose it all.
