You might want to change your strategy some then. Why not take trades where you can see a potential of 3-5%, and on occasion take a flyer and make 10%? Seems to make better sense since you're out in meetings and can't watch all the time. Trying to slice little gains here and there are for the guy that can babysit a trade all the time - although it ain't MY way either. Hit singles. When you connect good and get it by the outfielders and make a big gain, take that.
Actually, down here around 8.50 would have been ideal for a little more agressive trader - which ain't me - when it rejected going negative.
In addition to what Haroki said, make sure you know what you did wrong and therefore not do it again. Everybody makes bad trading calls, but not learning from those calls will eventually get your account to ZERO. You're a smart guy, so just keep a sharp memory of the bad calls, figure out the lesson to be learned, and learn the heck out of it.
I try to, and as you can read I tried to incorporate at least one lesson I learned into the story, what's frustrating is that even after I learned that particular lesson, it still bit me in the butt. Patience being the one I am talking about, even when I practiced more patience, the market still seems to turn when I finally give up on a position. I need to learn to improve my entries I think.
That's cause the recent down turn, there are still people jumping onto FAZ, and there are others trying to jump ship. And there are other's who got out, and then got back on this afternoon. FAZ was heaviy traded this week. It's a boat that I missed because I didn't think it was going to happen. Each day I suspect FAS would rebound and I was wrong each time.
