A wedge is a price pattern in which two trendlines slope in the same direction and move closer together. A rising wedge has both lines pointing up, and a falling wedge has both pointing down. The narrowing range suggests the move is losing strength, which is why many traders read wedges as signs of a reversal or a pause. The two shapes look alike, but they lean in opposite directions, and the reading depends on which way they lean and where they break.
This guide covers how to draw each wedge, why the shape is often read against the trend, and how to check a break before you act on it. A worked example uses invented prices. Wedges are judgement-based, and they break in the direction of the existing trend about as often as against it, so the rules here are starting points rather than guarantees.
What is a rising wedge?
A rising wedge forms when the price makes higher highs and higher lows, but the lower trendline rises more steeply than the upper one. The two lines converge as the range narrows. The pattern is usually read as bearish, because the rally is losing momentum, and a break below the lower line is treated as the signal.
The upper and lower lines should each have at least two touches, and the range should shrink over the course of the pattern. Rising wedges often form after a sustained uptrend, where each new high is reached with less buying. A rising wedge can also form inside a downtrend, where it appears as a bounce that is running out of strength before the decline resumes. In that case the break is more often downward and continues the existing trend. Context therefore matters as much as the shape. Check the trend that came before the wedge before you decide what the pattern means.
The difference in slope is what defines the wedge. If the two lines rise at about the same angle, the shape is closer to a channel, and it carries less of the squeeze that traders look for. Measure the angle of each line on the same scale, and check whether the lower line is clearly steeper before you call the pattern a wedge.
What is a falling wedge?
A falling wedge forms when both trendlines slope down, with lower highs and lower lows, and the upper line falls more steeply than the lower one. The range narrows as the decline slows. The pattern is usually read as bullish, because selling is losing strength and a break above the upper line can signal a reversal.
The checks mirror those for a rising wedge. Look for at least two touches on each line and a narrowing range. Falling wedges often form after a steep decline, where each new low meets less selling. They can also appear in an uptrend as a pullback, and in that case the break is more likely to be upward and to continue the trend. Like the rising wedge, the falling wedge is a context pattern, and its meaning changes with the trend it appears in.
Some traders also compare price with a momentum indicator such as the relative strength index. A falling wedge that makes a lower low in price while the indicator makes a higher low is a divergence, and some traders treat it as extra support for the bullish reading. That check is optional. It adds one more tool to test, and it has to be tested like the pattern itself.
How do you measure a break?
A wedge break is usually confirmed by a close beyond the lower line of a rising wedge or the upper line of a falling wedge. The textbook target is often the widest part of the wedge, projected from the break, but many wedges move differently. A retest of the broken line is a common step before a clean move.
The table uses invented prices for a rising wedge. The range narrows over three periods, and the close in the fourth period confirms the break.
| Period | Upper line | Lower line | Range (upper − lower) |
|---|---|---|---|
| Week 1 | 58 | 50 | 8 |
| Week 2 | 57 | 52 | 5 |
| Week 3 | 56 | 53 | 3 |
| Week 4 close | about 55 | about 53.5 | Close at 52, below the lower line |
The narrowing from 8 to 3 is the squeeze. The break came when the price closed at 52, below the projected lower line. The textbook target is the widest part of the wedge, 8 points, projected down from the break. That gives a reference level of about 45 in this example. Because the range had already shrunk to 3 points, the move that follows can be sharp, and a stop placed back inside the wedge limits the damage if the break fails.
Measure the break on the same chart you used to draw the lines. A break judged on a different timeframe, or with the lines redrawn after the event, is hard to repeat and easy to flatter.
Why do wedges fail?
Wedges fail when the break is a close inside the range, when the price returns through the broken line, or when the wider trend overwhelms the pattern. A rising wedge inside a strong uptrend can break down and then resume the rally, which is one of the most common ways the pattern misleads traders.
The shape is easy to draw after the fact and harder to draw in real time, because the lines depend on the points you choose. Two traders can draw different wedges on the same chart. To reduce that problem, write the rules in advance: how many touches you need, how much narrowing counts, and what counts as a close beyond the line. Also check how often the pattern has worked on your own past charts, not only on examples chosen to look clean. The backtest guide linked below explains why these checks matter for any chart pattern.
Timing is another source of failure. A wedge can take weeks to resolve, and a trader who acts on an early touch may be holding through a long, sideways period. Decide in advance how long you will wait for the break before you close the idea.
Common mistakes
Reading a wedge without the trend. The same shape can mean different things inside an uptrend and a downtrend. Always read it against the prior move.
Treating a touch as a break. The lower line of a rising wedge has to be broken by a close, not by a single wick that returns.
Setting a target without a stop. A wedge that breaks the wrong way can move quickly. Decide where the idea is wrong before you enter.
Checklist
- Check the trend before the wedge formed, and note whether it is up or down.
- Draw the two lines and confirm at least two touches on each.
- Check that the range narrows and that the lower line is clearly steeper, for a rising wedge, or the upper line steeper, for a falling one.
- Wait for a close beyond the line on the side of the break.
- Look for a retest of the broken line and see whether it holds.
- Set a stop on the other side of the wedge, so the idea is clearly invalid if the price returns.
- Record each wedge and its outcome, so you can measure the pattern's record on your own charts.
Key takeaways
A rising wedge has two upward-sloping lines that converge, and it is usually read as bearish on a clean break below the lower line. A falling wedge is the mirror image and is usually read as bullish on a break above the upper line. The trend before the pattern and the direction of the break matter as much as the shape, and the pattern should be tested before it is relied on.
