Yes. You can start with $2000 but don't day trade futures. Swing trade slow moving stocks while learning. IB is a good broker to be with and as a client you can open paper trading account and test day trading futures and stocks.
If you have 2k to daytrade, what would be the minimum stock price you should invest in, stocks from price range 1$ to 5$, 5$ to 10$ or 15 and up? what would bring you the most to break even?
