Problem is: don't do it.
I agree with the others.
As someone that has spent years trading stocks futures and warrants(a kind of option)...
And as someone who has read roughly a 100 books on trading, markets, investing, predictive finance...
And as someone who spent 5 years trying to write automated technical trader bots....
(And sought out and paid trading "experts" to learn from them in person)
I'm telling you: Don't do it.
The markets are pretty efficient.
Making money by trading is very very hard work.
You have significantly better odds with buying and holding high growth blue chips.
I know you want to trade.
But reconsider: at least paper trade for a year - this will open your eyes - and prove whether you are serious about becoming a professional, or just a dabbler about to lose a painful amount of money.
Don't do that. It's as simple as that.
Other than that, I recommend opening a debit account with TIAA-CREF.org and going from there.
The pitfall is to imagine beating the pros is likely both directly out of their money or indirectly by separating amateurs from their money.
That's not to say it isn't easy to make a small fortune. All it takes is starting with a large one.
Good luck.
