This was a HUGE lesson learned today. I had set a stop limit from previous shorts to cover at 6.95. Once I had covered all of my previous shares and had no shares for a stop limit, I had active position to focus on. However, when WATT reached 6.95, it triggered a buy off of my stop limit, which I didn't realize I must actively cancel. By the time I saw I had a position, I wasn't able to get out until 6.65, and lost $180. Lesson: Stop limits good, but actively close when no longer needed.
