Which is the best online trading platform?

Hi,
I was thinking of jumping into share market world with little investment for the next two years during my college time, so that I could learn the stock market out of the books!
I you guys could suggest me where to start from? There are so many options I want a good trading platform with lowest brokerage and minimal charges to setup the account.

I think that commodity & stock market are best online trading platform. I m also investing in commodity & stock market.

Hey, baby
Stock market books to show you in the next 2 years of my college days, I always wanted to jump into the market share of the world's small investment!
Where I can I suggest you start? I have a lot of small stock brokerage and lowest-cost platforms have a lot of options you want to set up an account.

all market is unpredictable, its very difficult. I like forec currency as the trading platform because its volatile is huge and fast to gain money there...
