I would think that doing this on a small level would eat at your profits rather quick. You have your broker fees which could be as high as $10. If you are only spending $100 to $200 you limit the number of shares you could buy, which also limits your profits. Let's assume a $10/share stock and you spend $200. You have your buy and sell commissions from the broker, which we could give a conservative estimate at $10 total. Right now you're at $220 and have 20 shares. You would have to have a $0.11 price swing in order to make a profit, and that profit is only $4. That assumes that the trade actually goes your way. It seems to me that you are not going to make much money if you are trading that little amount of money daily.
