An invented price line: three peaks after a rise, the middle one the highest, and then a fall, outlined by a neckline under the two dips between the peaks and the height of the head above it.
An invented chart, drawn to show the shape of a head and shoulders. Not market data.

How to recognise a head and shoulders
- A rise comes first. Without one there is nothing for the shape to reverse.
- Three peaks: a lower one, a higher one, a lower one again.
- Two dips between them, at roughly the same height. The line through them is the neckline, and it is often tilted.
- The shape is only complete, in the textbook sense, when the price closes below the neckline.
What it is taken to mean
It is read as a rise running out of buyers. The head makes a new high, but the right shoulder fails to reach it, so the sequence of higher highs has stopped. A close below the neckline then breaks the sequence of higher lows as well. Traders treat that as a possible change from an up-trend to a down-trend, not as proof of one.
That is a reading, and no more. A pattern is a description of what a price did, not a forecast of what it will do. Textbooks file this one under “reversal shapes”, which is a habit of naming and not a rule the market keeps.
How it is conventionally measured
The textbook measure is the height of the head above the neckline, taken straight down from the point where the neckline broke. It is a convention for describing the size of the shape. It is not a prediction, and prices fall short of it and pass it without regard for the drawing.
What traders check
- Whether there was a real rise before it. Three bumps in a sideways market are not this pattern.
- Whether the price has closed below the neckline, or only touched it.
- The time frame. A shape that took months to form on a daily chart carries more history than one drawn across an afternoon.
- What happens if the price returns to the neckline from below, which it often does.
Where people go wrong
- Naming it before the right shoulder has finished. Until the neckline breaks it is three peaks and nothing more.
- Tilting or moving the neckline until the shape fits.
- Treating the textbook measure as a destination.
- Forgetting that a failed head and shoulders, where the price climbs back above the right shoulder, is common.
On a real chart
Textbook shapes are rare. A real chart is ambiguous: the peaks are uneven, the lines can be drawn two or three ways, and the same candles are a head and shoulders to one reader and something else to another. Most shapes are also recognised only once they are finished, which is after the move they are said to announce has begun.
The picture on this page is invented. It was drawn by hand to show the shape as plainly as possible, with every awkward detail left out. It is not market data and it records nothing that happened.
Questions people ask
- Is a head and shoulders pattern bearish?
- It is classed as a bearish reversal shape, because it is drawn at the end of a rise and is completed by a fall through the neckline. The class describes the drawing. It does not say what the price will do next.
- Does the neckline have to be horizontal?
- No. It is the line through the two dips, so it slopes whichever way they do. Many textbook examples have a tilted neckline.
- Does a head and shoulders predict a fall?
- No. It describes what a price did while the shape formed. Published studies of chart patterns disagree about whether they tell anything about the next move, and the tidy examples in textbooks were chosen afterwards, when the outcome was known. It is one observation to weigh with others.
The words on this page
An explanation for study. It is not advice, a recommendation or a forecast, and a pattern described here says nothing certain about what a price will do next.
