Most of the time I am buying on a role-reversal support level or selling on a role-reversal resistance line, but in a rare instance I will trade the Wedge Pattern. A wedge, aka flag, pendent or triangle, is a fairly reliable price pattern that suggest a possible break out is about to occur. In this case, the buyers are showing an increase in volume as the stock closes right at the upper line on the wedge.
