Below is a snapshot of my morning gapper list. I didn't see any solid set-up, but I took only trade.
BLDR was nearing the red line on my gapper list shown on the screenshot. I took the short at 13.09 anticipating the break of the lower line, but covered at 13.23. I felt it was about to squeeze. I would have looked at the big picture and put my stop at 13.41. 13.50 This was yesterday support and turned resistance point today.
