Best advice I can give you:
Don't bother trying to trade, you'll lose your money to the market and your broker. Investing would be the best idea.
You have to think of it like this: some of the sharpest minds in the world are out to get your money when its in the market, and they want you to think you have a shot. Its like being given one chance to score on shaq....he's huge and does it for a living, you're just a kid...whats gonna happen?
What I recommend: Read the good books, paruse some sites, see if you'd be interested in trading...if you are educate yourself.
If you're not, don't trade, you're money will end up paying for some rich white guy's porsche (personally, I hope its me).
I didn't really sugar coat it, but thats how the market is and you should be aware....you position now is a bloody scuba diver trying to swim through a feeding frenzy of sharks. Don't do it, get in a boat and spend your money on somethign fun for you. Like a whore or a drug habit...thats what your age is all about.
