Ken, I've noticed in a couple of my "mistake" trades that I'll buy on the same day that a Magic Box confirms. Unfortunately, sometime after those mistake trades (on that same day), the Williams drops back down below -50, which kills the confirmation and leaves me stuck with a bum trade. As a result, I've learned to buy the day after a Magic Box is confirmed and 'locked in' by the close. Is that something you would recommend?
I just see many more "mistakes" happening if I try to get in too early (i.e. on the same day a Magic Box attempts to confirm).
