DAY TRADING???
You must be mad! That's not a profession, that's just gambling!!!
If you even touch the markets, then do it properly, by looking at "investing" in fundamentally valuable growth-stocks that look like they might maybe be worth more in 10 years, plus pay you a juicy 0.0001032% dividend or so per year.
Just look at the performance of stocks over the last 2-5 years.
Issues like YHOO went from $5 to $500+ in a couple of years! That's true value!
Now go and get yourself a trustworthy stockbroker and make sure you do the right thing.
Good Luck to You.
