Double Top Pattern: How to Spot and Trade the Reversal

A double top is a bearish reversal chart pattern in which price rallies to a high, pulls back, rallies again to roughly the same high, and fails. It is confirmed only when price closes below the low point between the two peaks, called the neckline. The pattern looks like the letter M and suggests buyers have twice failed to push through the same resistance.

This guide covers how to identify a valid double top, what confirms it, how to calculate the measured-move target, how to place entry and stop, and how it differs from head and shoulders. It is educational only, not financial advice. Patterns fail, past performance does not guarantee future results, and all numbers here are hypothetical.

Key takeaways

• A double top is two peaks at nearly the same price, usually separated by several weeks, with a pullback between them that defines the neckline.
• The pattern is not confirmed until price closes below the neckline; until then it is only a warning, and many double tops resolve upward.
• The measured-move target is the neckline minus the height from the peaks to the neckline, a rough guide and not a promise.
• Waiting for a retest of the neckline often gives a tighter stop and better reward:risk than selling the first break.
• For long-only traders, a confirmed double top is mainly an exit signal or a reason to avoid buying that stock.

What is a double top pattern?

A double top forms after an uptrend when price makes a peak, falls to a trough, rises back to about the same peak, and then fails again. The trough is the neckline support. A close below that support confirms the pattern.

The logic is supply and demand. At the first peak, sellers absorb the buying. After a pullback, buyers return for a second attempt, but sellers show up at the same level. When buyers cannot clear that price twice, the market sets a ceiling, and a break of the trough shows that demand has been exhausted.

What makes a valid double top?

A valid double top needs a prior uptrend, two peaks within a few percent of each other, a meaningful pullback between them, and a close below the neckline. Use these guidelines, which are conventions and not laws:

1. Prior uptrend. There must be a rally to reverse. A double top inside a sideways range is just a range.
2. Similar peaks. The second peak lands within about 1% to 3% of the first. A second peak that is clearly higher or lower is a different pattern.
3. Time apart. The peaks are typically separated by at least a few weeks on a daily chart. Peaks only a few days apart are usually just noise.
4. Meaningful pullback. The trough should be a visible decline from the peaks, often 8% to 20% depending on the stock's volatility.
5. Volume. Volume is often lighter on the second peak, which shows weaker buying, and heavier on the breakdown. This is a tendency, not a requirement.
6. Close below the neckline. An intraday dip does not count; wait for a close.

What is the neckline and why does it matter?

The neckline is the horizontal level at the low of the pullback between the two peaks. It is the line that turns a possible double top into a confirmed one. Until the neckline breaks, the stock is still in a range, and a bounce off it is an equally valid outcome.

Do not treat the second peak as the signal. Plenty of stocks make a second high near the first and then resume the uptrend, becoming a breakout instead. The neckline is the dividing line, and this is why confirmation matters more than the shape.

How do you calculate the measured-move target?

Subtract the pattern height from the neckline. Pattern height is the distance from the peaks down to the neckline.

Target = Neckline - (Peak - Neckline)

For example, with peaks near $60 and a neckline at $54, the height is $6, so the measured-move target is $48. It is a rough guide. Price may stall earlier at prior support, or overshoot. Treat the target as a planning tool, and use nearby support levels to decide where to take profits.

How do you trade a double top?

There are two common entries after the neckline breaks: sell the breakdown, or wait for a retest. A long-only trader uses the same signal to exit a long position or to avoid a new purchase.

• Breakdown entry: act on the first close below the neckline. It is fast but the stop is usually far away, up above the peaks.
• Retest entry: after the break, price often rallies back to the neckline, which now acts as resistance. A failed retest gives a much closer stop, just above the neckline.
• Stop: above the second peak for the breakdown entry, or just above the neckline for the retest entry.
• Target: the measured move, or the next support area, whichever comes first.

Worked example (hypothetical numbers)

A stock rallies to $60.00, pulls back to $54.00, rallies to $59.60 and rolls over. It then closes at $53.40 below the $54.00 neckline on higher volume.

• Height: $60.00 minus $54.00 = $6.00. Measured-move target: $54.00 minus $6.00 = $48.00.

The breakdown entry has a poor reward:risk because the stop must sit above the peaks. The retest entry is better only if the retest actually happens; many stocks drop without looking back, and then you have no trade. That is the trade-off: patience gives a better price but sometimes no fill. On a $50,000 account risking 1% ($500), the retest entry allows about 500 shares ($500 divided by $1.00), though remember that short positions have unlimited theoretical risk and many accounts cannot short at all.

For a long-only trader, the same chart says something simple: if you own the stock, a close below $54.00 is a reason to sell or tighten the stop. If you do not own it, there is little reason to buy until the pattern is resolved. See where to place a stop loss for more.

How do double tops compare with head and shoulders?

Both are bearish reversals confirmed by a neckline break, but the double top has two peaks at the same level and head and shoulders has three with a higher middle peak. The head and shoulders adds a failed higher high, which some traders view as stronger evidence of fatigue.

The bullish counterpart is the double bottom, and the inverted head and shoulders is the mirror of head and shoulders. Another bearish reversal to know is the rising wedge.

How do you avoid false double tops?

Most failures come from acting before confirmation. Use these checks:

• Wait for the close below the neckline. Many second peaks fail to reverse the trend.
• Check the trend context. In a strong bull market, a double top is more likely to resolve upward than in a weak one.
• Look for supporting signals. A shooting star or bearish engulfing at the second peak, or bearish divergence on RSI or MACD, adds evidence.
• Watch the breakdown volume. A break on thin volume has less conviction.
• Beware of failed breakdowns. If price quickly reclaims the neckline, the setup has failed and the stop is hit; do not argue with it.

Common mistakes with double tops

• Calling it too early. Seeing a second high and anticipating the pattern before the neckline breaks.
• Ignoring the larger trend. A double top against a powerful uptrend is less reliable.
• Using a stop that is too far to be practical. If the stop above the peaks gives a reward:risk below 1, reconsider or wait for the retest.
• Treating the target as certain. The measured move is a guide.
• Ignoring position sizing. Wide stops require smaller positions.

The bottom line

A double top is a simple, widely watched bearish reversal, but it only counts once price closes below the neckline. Use the measured move for planning, favor retests for tighter risk, and respect the stop. For long holders, a confirmed double top is a clear signal to review or exit the position.

StockSetups is long-only: it detects bearish patterns but filters them off the board, so a stock leaving the Breaking out and Broke out lanes is a quiet cue that a topping structure may be forming. Patterns fail, so manage risk and do your own research.
