What it is
The Descending Triangle is a bearish continuation pattern characterized by a flat support line at the bottom and a falling resistance line (lower highs) converging toward it. Price compresses until a breakdown occurs.
The pattern typically forms during downtrends and resolves with a downward breakdown approximately 70% of the time. The flat support shows buyers defending a level, while the lower highs show sellers becoming more aggressive.
The psychology
The descending triangle tells a story of mounting selling pressure. Price hits support and bounces - but each time it rallies, sellers step in at lower prices. They're becoming more impatient, less willing to wait for higher prices.
The buyers at support keep defending their level, but they're fighting a losing battle. Each rally fails at a lower high. Each lower high signals that the ceiling is falling. Eventually, the demand at support is exhausted.
When the breakdown comes, it's often sharp - all those shorts who were accumulating on lower highs are now vindicated, and buyers who were defending support capitulate. This is why volume typically expands on the breakdown.
Identification
- 01Flat support - Horizontal line with 2+ touches at same level
- 02Falling resistance - Descending trendline with 2+ lower highs
- 03Converging lines - Lines must converge to form triangle apex
- 04Prior trend - Typically forms in a downtrend (continuation)
- 01Volume contraction - Volume decreases during formation
- 02Volume expansion - Strong volume on breakout
- 03Clean structure - Well-defined resistance and support touches
- 04Breakdown in first 2/3 - Before triangle apex
- 01Sloping support - Must be horizontal for descending triangle
- 02Breakout instead - Price breaks above falling resistance
- 03Past the apex - Breakdown too late loses power
- 04Low volume breakdown - Weak conviction, may fail
Execution framework
Conservative: Enter on confirmed close below support with volume.
Aggressive: Enter on breakdown candle or short at falling resistance line.
Above the falling resistance trendline, or above the most recent lower high within the pattern.
Measured Move: Height of the triangle projected downward from breakdown point.
Typically 1:2 or better depending on where you enter relative to the falling resistance.
Context matters
The descending triangle is most reliable as a continuation pattern within an existing downtrend. Context determines whether to trade aggressively or wait for confirmation.
- 01Forms during established downtrend
- 02Clean, well-defined resistance and support
- 03Volume contracts during formation
- 04Volume expands on breakdown
- 05Multiple touches on both lines
- 06Breakdown occurs in first 2/3 of pattern
- 01Forms in an uptrend (reversal attempt)
- 02Messy, unclear structure
- 03Volume expands during formation (accumulation)
- 04Low volume on breakdown
- 05Pattern takes too long to resolve
- 06Against higher timeframe support
Volume typically contracts as the pattern develops. A breakout on heavy volume confirms the move - light volume breakouts often fail.
