Ascending and Descending Triangle Chart Patterns: Continuation Patterns Explained

Like other chart triangle patterns — such as the Pennant and Wedge — the Ascending Triangle and Descending Triangle are primarily continuation patterns, not reversal patterns.

Trading Signals for Ascending and Descending Triangle Patterns

The key distinction between ascending/descending triangles and symmetrical or expanding triangles is the presence of a clear horizontal line: support in the descending triangle, resistance in the ascending triangle.

In the Ascending Triangle pattern, price forms progressively higher lows while repeatedly testing a horizontal resistance level. After breaking above that resistance, price typically advances by a distance equal to the triangle’s base height — continuing the prior uptrend.

In the Descending Triangle pattern, the setup is mirror-image: price forms lower highs while repeatedly testing a horizontal support level. A breakdown below support confirms the continuation of the prevailing downtrend.

FAQ

What does an ascending triangle indicate?

An ascending triangle signals bullish continuation: rising lows meet flat resistance, often resolving with a breakout above resistance and upward price extension.

How do you measure the target after a triangle breakout?

Measure the vertical height of the triangle’s base (at its widest point) and project that distance from the breakout point.

Is a descending triangle bearish or bullish?

A descending triangle is bearish — it reflects weakening demand, with lower highs meeting flat support, typically resolving in a breakdown and further downside.
