Trade School. KBG1974, I'm sure you meant 4.36. Anyway, I use the 4/9/18 double-crossover for signals when I'm trying to trade a trend. In that it would've been a buy-alert on Nov 19/20 around 4, and a confirmed buy signal on Nov 30 around 4.15-4.20.
Since you're trading on trends, you should continue doing so until you get a sell-alert or a sell-confirmed.
Usually I mix crossover alerts and whatnot with support/resistance analysis and look for plays with favorable risk/reward. The closer your entry is to support, the less of a drop you need to sustain before you can stop out and not have to worry about just getting shook out and seeing the stock bounce back fast.
