Very good point. Just beware that you need to have a minimum of 25k (not including the money you are trading with) to get around the pattern day trader rule. If you don't have the 25k then you must wait for 3 days for your cash to clear after exiting a trade. This greatly reduces the number of trades you can do and your strategy. You may want to exit a trade after gaining 10% in one day but then that money will be tied up for 3 days. If you have a total of 5k you can kind of split it up into 1k trades so you can still make a few trades until those 3 days are up.
