Rising / Falling Wedge Reversal

A wedge is a price range bounded by two trendlines that converge and slope the same direction. A rising wedge slopes up — higher highs and higher lows, but the lower line rises faster so the range pinches shut. Despite the upward slope it is read as bearish: each new high carries less force, and the break is expected downward (against the slope). A falling wedge is the mirror — both lines slope down, range narrows, and the pattern is bullish, expected to break upward. The defining tension is that the break goes against the wedge's own slope. Both can appear as reversals (ending a prior trend) or as continuations (a pause inside an ongoing trend) — StockCharts is explicit that the rising wedge "can also fit into the continuation category," and that "regardless of the type (reversal or continuation), rising wedges are bearish."

The setup

Build the wedge from at least two reaction highs and two reaction lows (three of each is cleaner) — per StockCharts, every successive high and low sits above the prior one for a rising wedge, below for a falling wedge. The two lines must visibly converge.

  • Trigger: a convincing close through the line on the breakout side — the lower support line for a rising wedge, the upper resistance line for a falling wedge. The break is against the slope; that is the entire signal. Some traders wait for a break of the previous reaction low (rising) / high (falling) for extra confirmation.
  • Volume: ideally contracts as price grinds toward the apex, then expands on the break — StockCharts treats a volume expansion on the line break as confirmation. A break on flat or falling volume is suspect.
  • Entry: on the confirmed break (or on a throwback/pullback retest of the broken line, which is common — see below).
  • Stop: just back inside the wedge, beyond the most recent swing on the broken side.
  • Target: there is no clean measured move. StockCharts states plainly for the rising wedge: "There are no measuring techniques to estimate the decline — other aspects of technical analysis should be employed." A common heuristic is the wedge's widest (back) height projected from the break, but treat it as a rough guide, not a rule.

Base rates & evidence

Per Thomas Bulkowski (thepatternsite.com), the falling wedge actually breaks upward 68% of the time, yet he calls it "a poor performer as far as bullish chart patterns go." For the bullish upward break he reports a break-even failure rate of 26%, an average rise of 38%, throwbacks 62% of the time, and the price target met 62% of the time — and a performance rank of 31 of 39 for upward breaks. The rising wedge fares worse in Bulkowski's broader study; both wedges historically rank among the weaker patterns, with the falling-wedge bullish numbers flattering only because strong bull-market averages inflate the "average rise."

Honesty flags: (1) These are Bulkowski's historical, mostly daily-bar US-equity stats — not guarantees, and they vary by source. (2) Wedges are genuinely ambiguous between reversal and continuation; the slope tells you the expected break direction but not whether the prior trend ends or resumes. (3) High throwback rates (62%+) mean the break is frequently retested — fast entries get shaken out.

Strengths & limitations

The wedge's strength is a defined break level with a tight, logical stop just inside the apex, and a directional bias from the slope. The #1 misuse is trading the wedge before it breaks — fading the upper or lower line inside an un-broken, still-converging wedge. Until price closes through the breakout side on expanding volume, there is no signal; the apparent momentum loss can resolve either way. Second weakness: identification is subjective — converging trendlines can be drawn many ways, and a "wedge" is easily confused with a flag, pennant, or simple channel. Combined with mediocre base rates and frequent throwbacks, the wedge is best used as one confirming input alongside trend context and support/resistance, not as a standalone trigger.

System relevance

For swing entries, this maps to Augustus: detect a converging-trendline wedge, wait for the close against the slope with a volume expansion, size the stop just inside the apex, and discount the signal given the honest base rates and high throwback frequency.
