Triangle Pattern

What Are Triangle Patterns?

Triangle patterns are consolidation formations that appear when price oscillates within converging trendlines, creating a coiling effect. The narrowing range represents a compression of energy as buyers and sellers reach temporary equilibrium. This compression eventually resolves with a breakout that often leads to a significant directional move.

Triangles come in three forms: ascending (flat top, rising bottom), descending (declining top, flat bottom), and symmetrical (declining top, rising bottom). Each has a directional bias based on which side shows increasing pressure.

The Three Triangle Types

Ascending triangles show buyers willing to pay progressively higher prices (rising support trendline) while sellers defend a fixed level (horizontal resistance). This imbalance typically resolves in the buyers' favor, resulting in an upside breakout. The pattern appears in uptrends as a continuation and occasionally at bottoms as a reversal.

Descending triangles show sellers willing to accept progressively lower prices (declining resistance trendline) while buyers defend a fixed level (horizontal support). Sellers are typically more motivated, and the pattern resolves with a downside breakout. It appears in downtrends as a continuation pattern.

Symmetrical triangles have both trendlines converging with equal intensity. Neither side shows a clear advantage, making the breakout direction harder to predict. Most analysts default to expecting a continuation of the prior trend, but volume and momentum on the breakout should be used for confirmation.

Trading Triangles

Enter when price closes outside the trendline boundary, preferably with volume expansion. Stop losses go on the opposite side of the triangle (for ascending triangle longs, below the rising support line). The measured move target equals the height of the triangle at its widest point.

Timing matters. Breakouts that occur in the first two-thirds of the triangle's length (before the lines converge to the apex) tend to be more powerful. Breakouts near the apex may lack energy because the coiling process has dissipated too much momentum. If price reaches the apex without breaking out, the pattern is often invalidated.
