The Double Top Set-Up
Two highs at roughly the same price with a dip between them, and the low of that dip as the level the reversal is confirmed at.
MadStockAlerts Research · Updated September 4, 2026
What to take away
- The neckline is the low between the highs, and nothing is confirmed until it goes.
- Two highs a few sessions apart are a pause; two separated by a real decline are two failed attempts.
- Volume lighter on the second high than the first is the comparison that carries the pattern.
- Tops form faster and messier than bottoms, so this shape is usually less tidy than its mirror.
- The measured objective subtracts the pattern's height from the neckline.

The M that has not happened yet
Every high is the second high of a double top until it is not. Where the confirmation actually sits, and why tops form messier than bottoms.
This lesson is part of a Stock Alerts + Tools plan.
The shape
Price rallies to a high, falls back for several weeks, returns to roughly the same high, and turns down again. Drawn, it is an M, and the low of the dip between the two highs is the neckline that confirms it.
The mirror is structurally exact and visually messier. Tops are built out of impatience rather than resignation, so the two highs are more often at slightly different prices, the dip between them is sharper, and the whole structure takes less time than the equivalent bottom would.
- Two highs within a small percentage of each other, weeks apart.
- A decline between them large enough to be a decline, not a two-day dip.
- Lighter volume on the second high than on the first.
- A genuine advance into the first high, since a reversal needs something to reverse.

Why it forms
The first high is where an advance stopped, which says supply appeared at a price and nothing more. The dip that follows is that supply being tested by everyone who wanted to buy any weakness.
The second high is the test. Price returns to the same area, and the question is whether the buyers who drove the first advance are still there. A second high on visibly lighter volume says they are not — that the demand which produced the first one has largely been spent, and the same price is now being attacked by fewer participants.
Exactly as with the bullish mirror, the pattern is the neckline break and not the two highs. Every high in an uptrend is the second high of a double top until price goes above it, and the whole interval between the second high and the neckline is a period in which the shape has not yet formed and can still simply be an uptrend pausing.
| What to look at | Set-up intact | Set-up failing |
|---|---|---|
| Volume on the second high | Clearly lighter than the first | Equal or heavier than the first |
| Spacing of the highs | Weeks apart, with a real dip between | A few sessions apart, barely a pullback |
| The decline off the second high | Wide bars, closing near the lows | Shallow and overlapping, stalling early |
The price points that define it
A set-up is a shape plus a handful of prices. The shape is what makes it recognisable; the prices are what make it something that can be measured, reviewed afterwards and argued about honestly. These are the levels this one is read from.
| Level | Where it sits | What it tells you |
|---|---|---|
| The neckline | The low of the dip between the two highs | The reference the set-up completes through, and the only level in the shape that confirms anything. |
| The highs | The two turning points, at roughly the same price | The ceiling of the structure. Above them there is no double top, only an uptrend that hesitated. |
| The pattern height | The higher of the two highs minus the neckline | What the measured objective is scaled to, and a measure of how far the market ranged while the shape formed. |
| The second high's volume | Compared against the first high's | Not a price, and the most informative comparison available. It is what says the buyers have thinned out. |
Where the set-up completes
- 1The triggerThe set-up completes on a close below the neckline. Until then the two highs are just two highs, and the gap between the second one and the neckline is precisely where this pattern is most often called early and most often wrong.
- 2Where the reading stops holdingThe reading stops holding above the higher of the two highs. Some conventions use the second high alone; the higher of the pair is the level the structure actually rests on, and above it there is nothing on the chart the pattern can be describing.
- 3The measured objectiveThe conventional measured objective subtracts the pattern's height from the neckline. Tall double tops produce distant targets and the objective is reached less often than the break follows through — the neckline is the level that carries the information, and the target is an illustration of scale.
- 4Through the moveThe convention watches for the neckline to hold as resistance on the rally that usually follows the break. A market that breaks the neckline and then closes back above it has produced a failed top, and reclaimed tops tend to resume the original advance with some force.
Each of these describes where a convention puts a level, not what anybody should do at it. Whether a level is worth acting on at all is a question about position size, cost and the rest of a plan, and the answer differs for every account.
How often it follows through
Slightly under the bullish mirror, because tops form less tidily and because a long-run upward drift works against every bearish reversal. Properly spaced highs, lighter volume on the second, measured from the neckline break, is what the top of this band describes.
Read that as a floor rather than an expectation. A set-up that follows through two times in three still leaves one in three that does not, and the one that does not can move further and faster than the two that did. That arithmetic is what position sizing exists to answer, and no pattern improves it.
What this number is not
It is not our record, it is not a forecast for any particular chart, and it is not the rate at which the measured objective is reached — that is always lower. It is a conservative reading of how often a completed double top kept going before it went back through the level that invalidates it. Base rates move with the market, the timeframe and the exact definition used, and every one of those varies.
What failure looks like
The failure is the third push. Price breaks the neckline, cannot follow through, comes back and this time clears both highs — and what looked like a top turns out to have been a long pause. Because double tops are watched as closely as any shape here, the positioning below the neckline is one-sided, and the move through the highs is often faster than either of the rallies that formed them.
- The second high forms on volume as heavy as the first.
- The decline toward the neckline is shallow and overlapping.
- The break of the neckline closes back above it within a session or two.

Seeing it on a live chart
Compare the volume under the two highs before doing anything with the outline. A second high on heavier volume is not a failed test at all, and that single check discards most of the double tops people think they have found.
