The ascending broadening wedge consists of an upward sloping resistance line and a horizontal support line, and the opposite for the descending broadening wedge. The lines are drawn with a minimum of two contact points per line. Volumes tend to increase during the formation of the pattern and are at their maximum when prices break through the pattern. These chart patterns can be reversal or continuation patterns, but in 70% of cases, an ascending broadening wedge suggests a reversal of forex prices.
