Head and Shoulders Pattern: Neckline, Target and Failure

Three peaks are not a pattern until the neckline breaks

A higher peak sits between two lower ones on the daily chart, and the two pullbacks between them bottomed near the same price. Draw one line. The line through those two troughs is the neckline, and nothing about the head and shoulders pattern is decided until a daily close lands below it.

Take a daily chart. The left shoulder peaks at 148, the head at 156 and the right shoulder at 149. Both troughs bottom at 140, so the neckline is flat at 140. Fidelity’s chart-pattern notes describe the same three parts and state that the pattern is complete only when the neckline breaks; StockCharts’ ChartSchool treats the break the same way.

Write the rule first. On a daily chart the rule is a daily close below 140. An intraday dip to 139.5 that closes at 141 does not count, and a close at 139.2 does. The logic matches the neckline in a double top and double bottom: the swing between the peaks completes the reversal, and the peaks only set it up.

Necklines are rarely flat. The slope changes where the break happens, where the height is measured and how bearish the structure reads. StockCharts rates a downward-sloping neckline as more bearish than an upward one, and Bulkowski’s identification rules take a close below the right trough as the trigger when the line slopes down.

Two neighbours share this geometry. A right shoulder that keeps making lower highs into the 140 floor is turning into a descending triangle, and the triangle rules for the break apply. A head that barely clears the shoulders, say 150 against 148 and 149, is closer to a triple top and should be read as one.

Calculate the target once, then decide where the stop lives

Back to the same chart. The confirming daily close is 139.2, and the short fills at 139 on the next open. The height is the head minus the neckline: 156 − 140 = 16. The target subtracts that height from the neckline: 140 − 16 = 124. StockCharts and Fidelity describe the same projection, measured at the head and carried down from the line.

The target is fixed. The stop is a choice, and two placements turn the same 139 entry into two different trades. Both ratios below are before costs.

Stop B reads better and gets hit far more often. Pullbacks to the neckline are the norm: in Bulkowski’s bull-market sample of more than 2,800 tops, with statistics dated August 2020, price pulled back to the breakout level 68% of the time, and StockCharts notes that broken support commonly turns into resistance. A pullback that trades to 143 and closes at 140.5 takes out B and touches nothing else.

Run both plans through the risk-reward calculator before choosing, and decide now whether a stop at 142.5 gets a re-entry on the next close below 140. The breakout and retest guide covers the difference between a retest that holds and one that fails.

The inverse head and shoulders is the same structure upside down

Flip every rule. An inverse head and shoulders forms after a decline: a low, a lower low, then a higher low, with the neckline drawn across the two rallies between them. It is bullish, and it completes on a close above that neckline. StockCharts’ bottom page and Fidelity’s notes both describe it as the top pattern inverted.

Give it its own numbers on a separate daily chart. The left shoulder bottoms at 60, the head at 52 and the right shoulder at 59. The two rallies between them stall at 68, so the neckline is flat at 68. The height is again 16, from 52 up to 68, and the target is 84. A close above 68 completes it; a close back below 59 fails it.

Volume matters more on the way up. ChartSchool says a volume increase on the neckline break is welcome for a top and required for a bottom. A decline can run on thin volume; an advance needs buyers. The bottom also posts stronger numbers in Bulkowski’s bull-market sample: 71% of 3,197 bottoms reached the full target, as listed on his site in September 2026, against 51% of tops.

Failure means a close back above the right shoulder

Three things can follow the break. Only one is failure. Price can run toward 124. Price can pull back to the neckline, trade at 141 or 142 and turn down again, which is a retest with the pattern intact. Or price can close back above 140 and keep going; once it closes above the right shoulder at 149, the head and shoulders failure is complete and the 124 target is void.

Here is the failure case on the same chart. Day 1 closes at 139.2, the break. Day 3 prints a high of 141.8 and closes at 140.6, back above the line, which weakens the break without voiding it. Day 5 trades through 142.5 and closes at 143.4. Day 8 trades through 149.5 and closes at 150.2. Plan B lost 3.5, plan A lost 10.5, and 156 is the next reference above.

The cause is usually visible before the right shoulder finishes. A right shoulder above the left, at 151 against 148, breaks the symmetry the sources describe, because the second rally travelled further than the first. A break on a narrow bar with no rise in volume is weak. A daily top inside a rising weekly trend is often a pullback in a larger move, and strong support between 140 and 124 can stop the decline short of the target.

The target is a projection. In Bulkowski’s tops sample, 51% reached the full measured target, the average decline was 16%, and 19% failed to fall even 5%, his break-even failure rate. Many charts labelled head and shoulders are two highs and a hope until the right shoulder and the break are complete. Treat 124 as the reward input, and treat the close below 140 as the only completed fact.

Check the neckline on the screenshot before you trust the label

Check four things. Three peaks with the middle one highest. Two troughs, with a line drawn through them and extended to the right. The closing price against that line on the timeframe you trade, and the height arithmetic written next to it. If the right shoulder has not finished, the label is a watch note, and the alert belongs at the neckline rather than at the peaks.

TradeGPT reads the screenshot, so it sees what you cropped and nothing from a data feed. Keep all three peaks, both troughs and the bars after the break in the frame, and crop the order panel and account balance before you upload. In the report, the Patterns & Signals section names the structure it found, a neckline is drawn when one applies, and levels carry a strength rating and a distance from price.

A trade plan, when the report includes one, carries an invalidation condition; compare it with your own right-shoulder rule, and keep the axis text crisp in the crop so the prices it quotes line up with yours. The sample report shows the layout before you upload anything. When the three peaks and the break sit in one frame, analyze your own chart.

Questions traders ask about head and shoulders tops and bottoms

Is the inverse head and shoulders bullish or bearish?

Bullish. It forms after a decline, with the head as the lowest low and the neckline drawn across the two rallies between the lows, and it completes on a close above that neckline. In the example above, a close above 68 completes it and projects 84; a close back below 59 fails it.

How do you calculate the price target?

Measure the vertical distance from the head to the neckline directly beneath it, then project it downward from the break for a top. A head at 156 over a neckline at 140 gives a height of 16 and a target of 124. Bulkowski scales the height by the share of patterns that reached it, a nearer figure.

What causes a head and shoulders pattern to fail?

Demand that returns before the target. The usual tells are a right shoulder that climbs above the left, a break on a narrow bar with no rise in volume, and a daily top forming inside a rising weekly trend. Failure is confirmed by a close back above the right shoulder, 149 in the example, which voids the 124 target.

What volume confirms the breakout?

A rise in volume on the break bar, above what the right shoulder’s rally carried. ChartSchool calls that expansion welcome on a top and required on a bottom. Across the pattern, volume should fade from the left shoulder to the right; a right shoulder on the heaviest volume argues against the top.
