There are two ways to take a measurement from a symmetrical triangle. One is to measure the height of the base (AB); projected that vertical from the breakout point at C or the apex. Another method is to draw a parallel line upward from the top of the baseline (A) parallel to the lower line in the triangle.
Example of a bullish falling wedge. The wedge pattern has two converging treadlines, but slopes against the prevailing trend. A falling wedge is usually bullish
Example of an inverse head and shoulders. The rally from the head should see heavier volume and the breaking of the neckline should see a burst of trading activity.
Example of a double top. The pattern has two peaks (A and C) at about the same level. The pattern is complete when the middle trough at point B is broken on a closing basis. Volume is usually lighter on the second peak (C) and picks up on the breakdown (D). A return move back to the lower line is not unusual. The minimum measuring target is the height of the top...
