No good today

Made pretty good money today from GOOG day trade. NQ after Fed no loss, but stop loss is worse: 1531.5 to 1526 = 4.5 points. That's too much. I was gonna stop at 1528 but was tempted by a small quick bounce from 1528 to 1528.5. 10 seconds later, I was looking at 1526. I need to enter the stop in the system.
