WLD, actually, if am long and the top of the box is approached, that is when I lighten up. If you play the dark side that is when you want to load up. That allows you to put a stop not too far from the next box, but you should always assume that price will continue to be bound by the box "indefinitely", namely until the box is violated one way or another. If you are right and prices are still bound in that box, the next visit to the bottom of the box is when you cover your short (and where I buy my longs...).
