A descending triangle forms when price repeatedly tests a flat support level while making lower highs above it. The falling top and flat bottom converge into a triangle. It shows sellers becoming more aggressive with each bounce, selling at lower prices, while buyers defend a single level. Descending triangles are generally considered bearish and most often break downward, especially in downtrends.

## Anatomy

*Figure: Buyers hold one level while sellers keep selling lower, compressing price.*

| Feature | Description |
|---|---|
| Lower line | Horizontal support with at least two touches |
| Upper line | Falling trend line through lower highs, at least two touches |
| Volume | Often fades during formation, then rises on the breakdown |
| Bias | Bearish, especially within a downtrend |

## Why it tends to break downward

Each lower high shows sellers are willing to accept lower prices on every bounce, while the buyers at support are used up with each test. Stop losses from buyers accumulate just below support. When support finally gives way, those stops trigger and add to selling pressure.

## Trading the breakdown

1. **Identify** flat support with two or more touches and two or more lower highs.
2. **Wait for a close below support,** ideally on rising volume.
3. **Entry:** on the breakdown close, a sell stop just below support, or on a retest of broken support as resistance. See [Role Reversal and Retests](https://learn.tradelabsai.com/price-action/role-reversal-and-retests/).
4. **Stop:** above the most recent lower high, or above the retest high.
5. **Target:** subtract the triangle's height at its widest point from the breakdown level.

**Example: Measuring a descending triangle**
A coin has support at $0.82, and the pattern's first high is at $0.98, a height of $0.16. Highs fall to $0.93 and $0.88. Price closes at $0.80. The measured target is $0.82 minus $0.16 = $0.66. A trader shorts a retest at $0.815 with a stop at $0.865, above the last lower high, risking $0.05 for a potential $0.155.

## Descending triangles at the bottom of downtrends

Context matters. A descending triangle after a long decline, at a major higher timeframe support level, sometimes breaks upward instead, because selling has been exhausted. A break above the falling trend line in that situation can start a sharp rally as short sellers cover. Always respect the price action rather than the pattern's usual bias. See [Failed Breakouts and False Breaks](https://learn.tradelabsai.com/price-action/failed-breakouts/).

## Shorting considerations

- In stocks, shorting requires borrowing shares and carries borrow costs and squeeze risk. See [Short Selling](https://learn.tradelabsai.com/markets/short-selling/).
- Traders without shorting access can use the pattern to exit or avoid long positions, or use put options. See [Long Put](https://learn.tradelabsai.com/options/long-put/).
- In futures, forex and crypto derivatives, shorting is straightforward.

## Comparing the triangles

| Triangle | Upper line | Lower line | Usual bias |
|---|---|---|---|
| Ascending | Flat | Rising | Bullish |
| Descending | Falling | Flat | Bearish |
| Symmetrical | Falling | Rising | Neutral; follows the trend |

## Timeframes and reliability

Triangles appear on every timeframe, but patterns on daily and weekly charts that take several weeks to form are more reliable than small triangles on intraday charts, which form and fail constantly. Check the higher timeframe too: a triangle breaking in the same direction as the weekly trend has the wind behind it, while one breaking against a strong higher timeframe trend often stalls quickly.

## Common mistakes

- **Buying support** inside a descending triangle repeatedly as it weakens.
- **Shorting before the breakdown** with no clear invalidation.
- **Ignoring higher timeframe support** that may cause the pattern to fail.

## Frequently asked questions

### Is a descending triangle bearish?

Generally yes. Falling highs against flat support show growing selling pressure, and it more often breaks downward, though failures occur.

### How do you trade a descending triangle?

Wait for a close below support, enter on the break or a retest, place a stop above the last lower high and use the triangle's height for a target.

### Can a descending triangle break upward?

Yes, especially at major support after long declines. A close above the falling trend line signals the pattern has failed.
