Double Top: Definition, How to Trade, and Example

What Is a Double Top?

A double top is a bearish reversal chart pattern that forms after an uptrend. Price rallies to a resistance level, pulls back to a support level (the valley), rallies a second time to approximately the same resistance, and then rolls over. The resulting shape looks like the letter M. The horizontal line connecting the valley between the two peaks is the pattern's trigger line - its equivalent of a neckline.

The pattern reflects a shift in supply and demand. The first peak marks a level where sellers overwhelm buyers. The pullback to the valley shows sellers temporarily stepping aside. The second peak tests the same resistance, and when buyers fail again at that level, it confirms that the resistance is real and that the uptrend has stalled. The break of the valley completes the reversal.

Double tops appear on all timeframes. On a daily chart, the two peaks are typically separated by two to six weeks. On intraday charts, the formation can complete in hours. The longer the time between the peaks, the more significant the pattern tends to be.

How a Double Top Works

The mechanics are simple but powerful. The first peak creates a visible resistance level - a price where selling pressure overwhelmed buying interest. After the pullback, every market participant can see that level on the chart. When price approaches it a second time, traders watch closely: will buyers push through, or will sellers defend the level again?

When the second rally stalls at approximately the same price, it sends a clear message: buyers have had two chances and failed both times. This emboldens sellers and discourages buyers. The valley between the peaks becomes the last line of defense for the bullish case. Once it breaks, the crowd psychology flips - former support becomes resistance, and the decline accelerates as trapped longs liquidate.

The measured-move target is the vertical distance from the peaks to the valley, projected downward from the valley break. This target is a minimum expectation; the actual decline often exceeds it, especially when the broader market environment is also turning bearish.

How to Identify a Double Top

Not every pair of highs at a similar level constitutes a double top. The pattern requires specific context to be valid.

• A prior uptrend must precede the pattern - without one, there is nothing to reverse.
• Two distinct peaks at approximately the same price level. A gap of 1-3% between the peaks is acceptable; exact precision is rare.
• A clearly defined valley (pullback low) between the two peaks.
• Volume often diminishes on the second peak relative to the first, reflecting weaker buying conviction.
• Confirmation requires a close below the valley low, not merely an intraday wick.

How to Trade a Double Top

The standard entry is a short on a confirmed close below the valley support. Aggressive traders sometimes enter on the second peak itself, but this is anticipatory and carries a higher failure rate since the pattern is not yet confirmed.

The stop loss goes above the twin peaks. If price pushes to a new high above both peaks, the double top has failed and the uptrend may be resuming - you want to be out before that move extends.

The textbook target is the peak-to-valley distance, measured vertically and subtracted from the valley. This gives a minimum downside expectation. Traders often combine this with nearby support zones - prior swing lows, round numbers, or key moving averages - for more realistic profit-taking levels.

• Entry: short on a confirmed close below the valley support.
• Stop: just above the higher of the two peaks.
• Target: the peak-to-valley height projected down from the valley break.
• Confirmation: expanding volume on the valley break adds conviction; weak volume suggests a potential fakeout.

Limitations and Pitfalls

Double tops fail roughly one-third of the time, and the failures can be sharp. The most dangerous scenario is the valley fakeout: price breaks the valley support, triggers short entries, and then reverses hard to the upside - often breaking above both peaks on the next leg. This bear trap is common when the broader trend is strongly bullish and the double top forms as a minor consolidation within that trend.

Another frequent mistake is labeling the pattern too soon. A stock that pulls back from a high and starts rising again is not a double top until the second peak forms and the valley breaks. Shorting the pullback or the early stages of the second rally is guessing, not pattern trading.

Wide valleys weaken the pattern. If the valley between the two peaks is very deep (more than 15-20% of price), the pattern starts to look more like a broad trading range than a compact reversal formation, and the measured-move target becomes unrealistically large.

Example

A stock climbing steadily hits $95 and pulls back to $87 over two weeks. Three weeks later it rallies to $94.50 - close to the first peak but not above it - on noticeably lighter volume. It then begins to roll over. When the stock closes at $86.20, below the valley low of $87, the double top is confirmed.

The peak-to-valley distance is approximately $8 ($95 minus $87), so the measured-move target is about $79 ($87 minus $8). A short entry at $86.20 with a stop above the peaks at $95.50 gives approximately $9.30 of risk for a ~$7.20 target - about a 0.8:1 reward-to-risk at the textbook target. To improve the ratio, some traders tighten the stop to just above the second peak at $95 or wait for a retest of the $87 level from below before entering.

Bottom Line

The double top is one of the simplest and most intuitive reversal patterns: price tries twice to break a resistance level and fails. That failure, confirmed by a break of the valley support, signals a shift from bullish to bearish control. Traded patiently - waiting for the valley break rather than anticipating it - the double top provides a clear entry, a logical stop, and a measurable target. Just remember that one-third of the time the pattern does not follow through, and size your positions accordingly.
