The pattern has several criteria, and symbol TDG shown in Figure 3.1 provides a good example. First, you should have an ascending trendline acting as support; second, you should have a horizontal line representing the overhead supply of the stock that is slowly being eaten away by new buyers; and third, you should have a breakout above the horizontal line.

The chart in Figure 3.1 climbs a hearty 62 percent after its breakout before it has any meaningful retracement. If you want to establish an estimated target for a stock that has ...
