What is a Falling Wedge? Definition, Formula, and Example
A falling wedge is a bullish chart pattern formed by two downward-sloping, converging trendlines that resolves upward roughly 68% of the time, appearing both as a downtrend reversal and as a continuation pattern within an uptrend.
A falling wedge is a bullish chart pattern formed by two downward-sloping trendlines that converge as price compresses lower. The upper line (resistance) descends faster than the lower line (support), so the trading range narrows toward an apex. Statistically, falling wedges resolve upward roughly 68% of the time per Thomas Bulkowski's pattern encyclopedia. They appear in two contexts: as a reversal pattern terminating a downtrend, and as a continuation pattern during corrective pullbacks within a larger uptrend.
How to Identify a Falling Wedge
Five conditions must hold:
1. Two converging trendlines, both sloping down. Connect at least two reaction highs to draw the upper line and two reaction lows to draw the lower line.
2. Upper trendline steeper than the lower. This is the defining feature versus a descending channel, where the lines run parallel.
3. At least four touchpoints total — two on each trendline — to validate the pattern.
4. Volume contracts as price moves toward the apex, reflecting waning participation from sellers.
5. Breakout above the upper trendline on expanding volume confirms the pattern.
Pattern duration typically spans 3 weeks to 6 months. The measured-move price target adds the wedge's maximum height (the vertical distance between trendlines at the widest point) to the breakout price.
Worked Example: SPY in 2023
The SPDR S&P 500 ETF SPY carved a textbook falling wedge between August and October 2023. Price descended from $460 to $410 over roughly 10 weeks. The upper trendline dropped from $460 to $425 while the lower trendline descended only from $440 to $410 — classic convergence with the upper line steeper than the lower.
Volume contracted through September. The breakout came on October 27 with a close above $425 on volume 40% above the 20-day average. Wedge height at its widest measured ~$30; added to the $425 breakout price, that implied a $455 target. SPY reached $459 by November 24 and ran to $475 by year-end — both the measured-move and the broader trend continuation satisfied.
When Traders Use Falling Wedges
Three primary applications:
- Reversal entries: in established downtrends, the wedge breakout marks trend exhaustion. Long entries take place on the breakout candle close or on a retest of the broken trendline as new support.
- Pullback continuations: within an uptrend, a falling wedge represents a corrective pause. Breakout long entries align with the higher-timeframe trend and offer favorable risk-reward.
- Stop placement: stops typically sit a few percent below the most recent swing low inside the wedge, providing a tight risk-defined trade.
The pattern's bullish bias makes it popular in long-only equity strategies and as a confirmation tool for swing entries.
Limitations and Misconceptions
Falling wedges are subjective — two analysts can draw different trendlines on the same chart and arrive at different breakout levels. The 68% upward break rate leaves a meaningful 32% that fail or resolve down, and downside resolutions are often sharp because the compressed structure traps long positions. Low-volume breakouts fail at far higher rates than high-volume ones, so volume confirmation is mandatory. The pattern also gets confused with descending channels (parallel lines, neutral bias) and with garden-variety pullbacks — neither carries the same statistical edge.
