As long as it works, you follow it, when it does fail, stops should keep you out and raise cash. It was a tough day, yet, only KLAC and ZBRA (out the ones I have) really went down more than I expected. I was weighing adding a third position in ZBRA, but with cash that low, I thought I may wait for other deeper discount bargains. For instance, the print under $22.02 today got me out of CREE, since that is an important breach.
