Makes a great gift

Rising wedges, especially for downward breakouts, are some of the worst performing chart patterns. Downward breakouts have unacceptably high failure rates and small postbreakout declines. Also, pullbacks occur almost two-thirds of the time and throwbacks happen almost three-quarters of the time. For more information see pages 811 to 826 of the book Encyclopedia of Chart Patterns, Second Edition and the following...

Identification Guidelines

Characteristic Discussion
Price trend Can be any direction leading to the pattern
Shape A narrowing and rising triangle shape.
Trendlines Price bounces between two up-sloping and converging trendlines.
Touches Price should touch each trendline at least five times to outline a good pattern. That’s 3 touches of one trendline and 2 of the opposite.
Duration 3 weeks is the minimum duration, otherwise it’s a pennant.

Volume trend

Trends downward at least 74% of the time until the breakout.
Breakout Can be in any direction but is downward 69% of the time.
Confirmation The pattern confirms as a valid one when price closes outside one of the trendlines.

Trading Tips

Trading Tactic Explanation
Measure rule For downward breakouts, the lowest valley in the pattern (A) is the price target. Alternatively, compute the height from the highest peak (B) to the lowest valley (A) and then multiply it by the above “percentage meeting price target.” Add it to (upward breakouts) or subtract it from (downward breakouts) the breakout price (the point at which price crosses the trendline, shown in the Measure Rule figure to the right as a blue line) to get a price target (C).
Breakout The average distance to the breakout is 58% to 64% of the way to the triangle apex (where the trendlines join).
Confirmation Wait for a close outside one of the trendlines before taking a position.

Throwbacks and pullbacks

Throwbacks and pullbacks hurt performance.
Weakness Upward breakouts may show weakness two weeks after the breakout.
Width Wide patterns perform better than narrow ones.

Example

Rising wedge chart pattern example

The above figure shows an example of a rising wedge chart pattern. Each trendline has at least three distinct minor high or minor low touches, sandwiched between two converging trendlines. The upward breakout from this rising wedge is unusual because of its rarity. A throwback follows the breakout in this example.
