# Triangle and Wedge Patterns: Ascending, Descending, Rising, and Falling

*9 min read | July 2026 | Tags: Chart Patterns, Technical Analysis, Swing Trading*


Thomas Bulkowski's bull-market perfect-trade study of [descending triangles](https://www.thepatternsite.com/dt.html) reports that confirmed patterns broke upward 53% of the time. Triangle and wedge names describe shape, not a guaranteed outcome. These historical study results are not forecasts for individual trades. This guide covers all three triangle variants (ascending, descending, symmetrical) and both wedge variants (rising, falling), the anatomy each shares, the conventional measured target, and how to assess them alongside EasySwing's market-regime context.

## Triangle and Wedge Patterns, Defined

Triangles and wedges are consolidation patterns where two converging trendlines compress a stock's trading range before a breakout resumes or reverses the prior move. Both shapes form as buyers and sellers narrow their disagreement over price, squeezing volatility toward a point until one side wins decisively.

The two shapes are distinguished by their trendline slopes. A triangle has one flat boundary and one sloped boundary (ascending and descending triangles), or two boundaries converging from opposite directions at similar angles (symmetrical triangle). A wedge has both boundaries sloping in the **same** direction — both rising or both falling — which is what separates a wedge from a triangle even though both compress toward a point.

## The Three Triangle Patterns

All three triangle types share the same converging-boundary anatomy, but Bulkowski publishes different results for [ascending](https://www.thepatternsite.com/at.html), [descending](https://www.thepatternsite.com/dt.html), and [symmetrical](https://www.thepatternsite.com/st.html) triangles. The figures below come from those bull-market perfect-trade studies and should be read within that methodology.

| Pattern | Boundary Shape | Sample Size (Bulkowski) | Breaks Up | Best Upward Rank |
|---|---|---|---|---|
| Ascending Triangle | Flat top, rising bottom | 1,400+ trades | 63% of the time | 16 of 39 |
| Descending Triangle | Flat bottom, falling top | 1,300+ trades | 53% of the time | 33 of 39 |
| Symmetrical Triangle | Converging from both sides | 3,000+ trades | 60% of the time | 36 of 39 |

### Ascending Triangle

The **ascending triangle** has a flat resistance line at the top and a rising support line at the bottom — each pullback finds a higher low, while the ceiling stays fixed. It is traditionally classified as a bullish continuation pattern, and Bulkowski's data supports that classification: 63% of confirmed ascending triangles break upward.

Upward breakouts carry a 17% break-even failure rate, average a 43% rise, and meet their price target 70% of the time — a rank of 16 out of 39 bullish patterns, making it the strongest performer of the three triangle types on the upside. Downward breakouts (the remaining 37%) are considerably weaker: 38% failure rate, a 13% average decline, and only 44% meeting target, ranking 30 of 36 bearish patterns.

### Descending Triangle

The **descending triangle** inverts the ascending triangle's shape — a flat support line at the bottom and a falling resistance line at the top, each rally failing at a lower high. Despite the bearish-sounding name, Bulkowski's tracked data shows it breaks upward 53% of the time, slightly more often than down.

Upward breakouts carry a 22% failure rate, average a 38% rise, and meet target 64% of the time (rank 33 of 39). Downward breakouts carry a 23% failure rate, a 15% average decline, and a 50% target-met rate (rank 15 of 36) — meaningfully stronger relative performance than its upward breakouts, and the better of the two directions once a breakdown actually confirms. Bulkowski also notes that upward-breakout performance on this pattern has weakened substantially since the 1990s, which is worth factoring into how much weight the historical average deserves today.

### Symmetrical Triangle

The **symmetrical triangle** has both boundaries converging toward each other at similar angles, forming a shape that narrows evenly from both sides rather than favoring one direction visually. It is the most common of the three triangle types in Bulkowski's sample — over 3,000 tracked trades — and breaks upward 60% of the time.

Upward breakouts show a 25% failure rate, a 34% average rise, and a 58% target-met rate, ranking 36 of 39 — the weakest upward performer among the three triangle types despite being the most frequently occurring. Downward breakouts are weaker still: 37% failure, a 12% average decline, 36% meeting target, ranking 34 of 36. The symmetrical triangle's popularity in retail chart-reading outpaces its actual measured reliability.

## The Two Wedge Patterns

Both wedge variants have boundaries sloping in the same direction, and — unlike triangles — a wedge's classification as bullish or bearish comes from its slope direction, not from the trend it appears inside.

### Rising Wedge

A **rising wedge** has both boundaries sloping upward, with the lower boundary rising faster than the upper one, squeezing the range as price grinds higher. It is conventionally classified as bearish regardless of whether it appears inside an uptrend or a downtrend. Bulkowski's [rising-wedge study](https://www.thepatternsite.com/risewedge.html) ranks its downward-breakout performance last among the 36 bearish patterns in that comparison.

The more common downward breakout carries a 51% break-even failure rate, an average decline of just 9%, and only 32% of trades meeting their price target — a rank of 36 out of 36 bearish patterns, dead last. A rising wedge that breaks down is barely more reliable than a coin flip, and even when it works, the average move is small relative to almost every other pattern tracked.

### Falling Wedge

A **falling wedge** has both boundaries sloping downward, with the upper boundary falling faster than the lower one. It is conventionally classified as bullish, but Bulkowski's [falling-wedge study](https://www.thepatternsite.com/fallwedge.html) reports middling results: upward breakouts carry a 26% failure rate, a 38% average rise, and a 62% target-met rate, ranking 31 of 39. Downward breakouts carry a 29% failure rate, a 14% average decline, and a 29% target-met rate, ranking 27 of 36.

In that study, the falling wedge is a weak relative performer among bullish chart patterns. Its recognizable shape is not enough on its own to establish conviction.

## Measuring the Price Target

The standard measuring technique for all five patterns is the same: measure the vertical height of the pattern at its widest point (the base, where the two boundaries are furthest apart), then project that same distance from the breakout point in the breakout direction.

For an ascending or descending triangle, measure from the flat boundary to the sloped boundary at the pattern's starting width. For a symmetrical triangle, measure the same way at the point where the two boundaries begin converging. For either wedge, measure the vertical distance between the two boundaries at the wedge's widest point. Stop placement follows the same logic as any breakout trade: below the triangle or wedge's lower boundary for a long entry, above the upper boundary for a short entry.

Throwbacks and pullbacks — price returning to retest the broken boundary — appear frequently in the linked studies. A retest alone therefore does not establish that a breakout failed; the subsequent close and structure matter.

## Regime Dependence

None of these five patterns should be assessed independently of the broader [market regime](/blog/market-regime-bull-bear-choppy). EasySwing reports five categorical states — Trending Up, Trending Down, Ranging, High Volatility, and Transitioning — from market-level inputs including SPY price structure, breadth, McClellan momentum, and VIX. They are not a linear Strong Bull-to-Strong Bear scale, and Transitioning does not specify a direction.

- **Trending Up:** Bullish breakouts are aligned with a supportive market backdrop; bearish breaks are fighting it.
- **Trending Down:** Bearish breaks are aligned with the market backdrop; bullish breaks need stronger independent confirmation.
- **Ranging:** A converging-boundary shape can simply be range compression rather than a durable directional signal.
- **High Volatility:** Wider daily ranges can make boundary breaks noisier and increase practical execution risk.
- **Transitioning:** Signals are mixed or inputs are incomplete; the label is deliberately direction-neutral.

A symmetrical triangle breaking upward during a Trending Down market is fighting the broader backdrop. Stock-level [RS rank](/blog/relative-strength-rank-rs-90-swing-trading) can provide separate context, but it is not a directional transition label or a substitute for breakout confirmation.

## How EasySwing Relates to Triangle and Wedge Setups

EasySwing does not run a standalone triangle or wedge shape classifier. The pattern therefore requires a trader's own visual assessment and breakout confirmation; a scanner result should not be described as detecting or confirming this geometry.

EasySwing's active [VCP Breakout](/blog/vcp-setup-volatility-contraction-pattern) detector uses its own contraction and pivot rules; it does not classify triangles or wedges. Bear Flag is a separately registered setup and should not be treated as a wedge classifier. A stock may independently qualify for a named setup after a boundary break, but that is a separate signal. Run a scan at [strategies](/strategies) to see which setups are currently live.

## Practical Checklist

Before treating a converging-boundary structure as a tradeable triangle or wedge, verify these conditions:

✅ Both boundary lines are drawn from at least two touches each — a single touch on either side is not a validated trendline
✅ Volume contracts as the pattern narrows toward its apex, and expands on the breakout
✅ A daily close confirms the break — a wick-only touch of the boundary is not confirmation
✅ The broader [market regime](/blog/market-regime-bull-bear-choppy) supports the breakout direction
✅ RS rank confirms the direction — improving for bullish breaks, deteriorating for bearish breaks

❌ Do not assume a descending triangle breaks down just because the name sounds bearish — Bulkowski's data shows it breaks up slightly more often than down
❌ Do not treat a rising wedge breakdown as a high-conviction short — it ranks dead last (36 of 36) among bearish patterns in Bulkowski's data
❌ Do not enter before the pattern has at least two touches on each boundary
❌ Do not chase a breakout that has already traveled most of the measured-move distance before you can enter

## Frequently Asked Questions

**What is the difference between a triangle and a wedge pattern?**

A triangle has boundaries that either converge from opposite directions (symmetrical) or pair one flat boundary with one sloped boundary (ascending, descending). A wedge has both boundaries sloping in the same direction — both rising or both falling. That shared slope direction is what makes a wedge's classification (bullish or bearish) independent of the trend it appears inside, unlike a triangle.

**Which triangle pattern is the most reliable?**

Among the three, the ascending triangle has the strongest upward-breakout performance in Bulkowski's data: a 17% break-even failure rate, a 43% average rise, and a 70% target-met rate, ranking 16 of 39 bullish patterns. The symmetrical triangle, despite being the most common of the three, ranks weakest on the upside (36 of 39) even though it still breaks upward 60% of the time.

**Is a rising wedge always bearish?**

Yes — a rising wedge is classified as bearish regardless of whether it appears inside an uptrend (as a reversal warning) or a downtrend (as a continuation pause), because its defining feature is the slope of its two boundaries, not the trend around it. Bulkowski's data shows it is also one of the weakest patterns overall: a downward breakout carries a 51% break-even failure rate and ranks dead last (36 of 36) among bearish patterns.

**Do descending triangles always break down?**

No. Despite the bearish-sounding name, Bulkowski's tracked data on descending triangles shows a confirmed breakout resolves upward 53% of the time — slightly more often than downward. The pattern's name describes its shape (a falling resistance line over a flat support line), not a guaranteed outcome.

**Does EasySwing screen for triangle and wedge patterns?**

No. EasySwing does not currently expose a standalone triangle or wedge detector. A stock may separately qualify for an active named setup, but that result does not detect or confirm triangle or wedge geometry.
