Generally speaking, in any trading aspect, you should be organizing your trades based on Risk:Reward. Usually you want to go after a 2:1 or 3:1. So don't look at it in terms of the money your making, but the percentage of gains you are getting. If you can gain 10% a week, you are a consistant profitable trader. They last longer in the markets than the one guy that makes 50% off one trade, but loses 6 other ones for 20% each.

You will have some trades that are sold off early, but if it was a comfortable exit point for you, you're doing it right.
