Symmetrical Triangles: Identification Guidelines

CharacteristicDiscussion
Price trendCan be any direction leading to the chart pattern.
ShapeTriangular. Prices move between two converging trendlines.
TrendlinesTwo trendlines bound prices; the bottom trendline slopes up and the top one slopes down.
CrossingPrice must cross the pattern from side to side, filling the triangle with price movement, not white space.
TouchesPrice must touch one trendline at least three times and the other trendline at least twice, forming distinct valleys and peaks.
VolumeTrends downward 86% of the time.
BreakoutUpward 60% of the time and 73% of the way to the triangle apex (upward breakout) and 74% of the way for downward breakouts.

Symmetrical Triangles: Trading Tips

Trading TacticExplanation Symmetrical triangle measure rule
The Measure Rule
Measure ruleCompute the height from the highest peak (point A in The Measure Rule figure to the right) to the lowest valley in the pattern (B) then multiply it by the above 'percentage meeting price target.' Add it (upward breakouts) or subtract it (downward breakouts) from the breakout price. The breakout price is the point at which price pierces the trendline. The figure shows an upward breakout with target price C.
Breakout volumePatterns with heavy breakout volume (above the 30-day average) do better.
Yearly lowTriangles with breakouts within a third of the yearly low perform best (based on the median rise).
Trend startTriangles perform best post breakout when they appear at the start of trends.
Throwbacks and pullbacksThrowbacks and pullbacks hurt post breakout performance.

 

Expect the market to turn when it reaches the apex of the triangle. See Triangle Apex and Turning Points.

Symmetrical Triangles: Example

The figure to the right shows an example of a symmetrical triangle chart pattern.

The consolidation pattern of the symmetrical triangle forms as volume recedes. Then, price breaks out downward, but within a few days, price reverses and shoots out the top of the symmetrical triangle, busting the pattern and leading to a strong move upward.

Busted patterns (when the breakout is in one direction only to see price reverse and breakout in the opposite direction) often result in strong moves. However, symmetrical triangles have a tendency to double bust -- the final breakout direction is the same as the original one.
