Tiếng ViệtWhat Is a Double Top Pattern? How to Trade It in Crypto
by PrivaccUpdated September 25, 20269 min read
A double top is a bearish reversal pattern: price reaches a high, pulls back, returns to roughly the same high, fails again, and then falls through the low between the two peaks. On a chart it looks like the letter M. This guide covers how to identify one, why it is not a double top until the neckline breaks, how traders plan around it — including if you can only buy and sell — and the ways it fails.

What is a double top pattern?
A double top forms when price rises to a high, falls back to a support level, rises to about the same high a second time, and is turned away again. When price then closes below that support level — the neckline — the pattern is complete.
It is a reversal pattern. Two failed attempts at the same price suggest buyers have run out of strength there, and the break of the neckline is the evidence that sellers have taken over.
The anatomy of a double top
Four parts, each of which carries information.
The prior uptrend
There has to be something to reverse. A double top forms after a meaningful rise; two equal highs in a sideways market are just a range.
The first peak
Price makes a high and turns down. On its own this is unremarkable — every rally has pullbacks.
The neckline
The low of the pullback between the two peaks. It is the level that matters most, because the pattern is not confirmed until it breaks.
The second peak
Price returns to roughly the first high and fails there again. The two peaks do not need to be identical — close is enough — but a second peak well above the first is a new high, not a double top.
How to identify a double top
The shape is easy to see and easy to see too early. These checks help.
Wait for the neckline
The most common mistake is calling a double top at the second peak. Until price closes below the neckline, what you have is two highs and a possible pattern — and many possible double tops go on to break higher.
Look for similar peaks
The peaks should be close in price. The closer they are, the clearer the message that buyers failed at the same level twice.
Allow time between them
Two peaks a couple of candles apart are noise. A meaningful double top has a real pullback and recovery between the highs.
Check volume on the second peak
Volume is often lighter on the second peak than the first — fewer buyers willing to push — and heavier on the break of the neckline.
What the pattern says about buyers and sellers
At the first peak, buyers push price to a level where sellers outweigh them. On the pullback, some buyers step in again and drive a second attempt. When that attempt stalls at the same level, it shows the same sellers are still there — and when price then falls through the neckline, the buyers who stepped in on the pullback are underwater, and some of them sell too.
How to trade a double top
Traders use the pattern to set a plan: where to act, where the idea is proven wrong, and a rough objective. Nothing in this guide is financial advice.
Entry
The usual trigger is a candle close below the neckline. Acting before that is acting on a guess.
Stop
The stop commonly sits just above the two peaks. If price rises through them, the double top has failed and the trend has resumed.
Target
The conventional objective is the height from the peaks to the neckline, projected down from the neckline. With peaks at 150 and a neckline at 126, the height is 24 and the target 102. It is a rule of thumb, not a forecast.
Size
The stop above the peaks can be a long way from the entry, so size matters more than usual. Choose it so being wrong costs an amount you accept.
Using a double top when you cannot short
A swap interface lets you exchange tokens you hold, not short them. For most people the pattern is useful in two plainer ways: as a prompt to reconsider a holding when the neckline breaks — some swap part of it into a stablecoin and keep the rest — and as a reason not to buy the second peak just because the price looks familiar.
Double top vs double bottom
The double bottom is the exact mirror: two roughly equal lows with a peak between them, confirmed when price breaks up through that peak. One marks buyers failing twice at a high; the other marks sellers failing twice at a low.
Double top vs triple top vs head and shoulders
Several reversal patterns share the same idea — repeated failure at a high, confirmed by a break of support — and differ mainly in the number and shape of the peaks.
| Double top | Triple top | Head and shoulders | |
|---|---|---|---|
| Peaks | Two, roughly equal | Three, roughly equal | Three, the middle one highest |
| Confirmed by | Close below the neckline | Close below the neckline | Close below the neckline |
| Usual reading | Bearish reversal | Bearish reversal | Bearish reversal |
| Common target | Pattern height below the neckline | Pattern height below the neckline | Head height below the neckline |
How reliable is the double top?
Once the neckline breaks, it is a reasonably well-regarded reversal signal; before that, it is not a signal at all. Published success rates vary with market, timeframe and definition, and should not be carried over to thin tokens.
Where it tends to work better
After an extended rise, with clearly similar peaks, lighter volume on the second peak, and a decisive, high-volume break of the neckline.
Where it tends to work worse
In sideways markets, on very short timeframes, on thin tokens, and when the neckline break comes on weak volume.
When a double top fails
The pattern fails when price holds above the neckline and goes on to break above the peaks instead. What looked like a top was a pause, and the rise that follows can be sharp as anyone who sold into it buys back.
A second kind of failure is a neckline break that immediately reverses — price closes below, then climbs back above within a few candles. That is one reason traders wait for a close and keep a defined stop.
Double tops in crypto: what is different
A few crypto-specific things change how the pattern reads.
Wicks overshoot peaks
Thin liquidity produces long wicks that poke above a previous high and fall back. Judging the peaks on closes rather than wicks avoids mistaking a wick for a new high.
Round numbers attract peaks
Double tops often form at round prices or previous all-time highs, where many holders have orders or intentions to sell.
Liquidity decides meaning
On a deep market the pattern reflects many participants; on a small token it may reflect a few wallets and means much less.
News overrides it
An announcement can send price through both peaks in minutes. The stop is there for that.
A worked example
A token rises from 0.80 to 1.20, falls back to 1.05, climbs again to 1.19 and turns lower. The neckline is at 1.05, and the pattern's height is 1.20 − 1.05 = 0.15.
Nothing is confirmed until a candle closes below 1.05. When one does, a trader following the conventional plan treats that close as the trigger, places a stop just above the peaks at around 1.22, and projects 1.05 − 0.15 = 0.90 as the objective. The stop sits 0.17 above the entry against a potential 0.15 — a poor ratio on those numbers, and worth noticing before acting rather than after.
For someone holding the token rather than trading it, the same close below 1.05 is simply the moment to decide whether to keep holding — perhaps swapping part of it into a stablecoin — rather than waiting to see whether 0.90 arrives.
Common mistakes
The double top is simple to describe and easy to misuse.
Calling it at the second peak
Two similar highs are not a double top until the neckline breaks. Acting at the second peak is acting on a guess, and many such guesses end in a new high.
Ignoring the trend before it
Two equal highs in a sideways market are the top of a range, not a reversal. The pattern needs a rise to reverse.
Mistaking a wick for a peak
In thin markets a single spike can poke above a prior high and fall straight back. Reading peaks on closes avoids treating that as a second top — or as a failed one.
Setting the stop too tight
A stop inside the pattern, below the peaks, is hit by ordinary noise. The logical stop is above the peaks, which is why the distance deserves a look before acting.
Practise on a live chart
Look for two similar highs with a real pullback between them — and then notice how often the neckline holds. The chart below is live, drawn from on-chain trades in your browser.
Pros and cons of the double top
Useful, with a clear discipline attached.
Pros
It has a clear confirmation level, a logical stop and a defined objective, and it is easy to recognise on any timeframe.
Cons
It is very often called too early, the stop above the peaks can be distant, neckline breaks can reverse, and the target is a convention rather than a forecast.
Frequently asked questions
Is a double top bullish or bearish?
Bearish. It is a reversal pattern that suggests an uptrend is ending — but only once price closes below the neckline.
When is a double top confirmed?
When price closes below the neckline, the low between the two peaks. Before that it is only a possible pattern.
Do the two peaks have to be exactly equal?
No. They should be close in price. A second peak well above the first is a new high rather than a double top.
How do you calculate a double top's target?
Measure from the peaks down to the neckline and subtract that distance from the neckline. Peaks at 150 and a neckline at 126 give a target of 102. It is a rule of thumb.
Where do traders put the stop?
Usually just above the two peaks. If price rises through them, the pattern has failed.
What is the difference between a double top and a double bottom?
They are mirror images. A double top is two equal highs that break down through support; a double bottom is two equal lows that break up through resistance.
Can I use a double top without shorting?
Yes. It is useful for deciding when to reconsider a holding — for example swapping part of it into a stablecoin when the neckline breaks — and for not buying the second peak.
Does the double top work in crypto?
It appears on crypto charts as anywhere, but long wicks, thin liquidity and news make it less dependable on small tokens than on deep markets.
