Head and Shoulders: definition and measured success rate
Data as of 16.09.2026 · back-test since 10/2020
A head and shoulders is a bearish reversal pattern made of three highs: a highest middle peak (the head) framed by two lower peaks (the shoulders). A close below the neckline connecting the interim lows completes the pattern. In chartval's back-test, it worked in 41 of 100 comparable cases (6,673 occurrences).
How does a head and shoulders form?
An uptrend prints its final extreme at the head, but the next advance already fails at a lower level. Buyers defend the neckline several times. When it breaks, a long topping process resolves downward, one of the most-studied reversal structures in technical analysis.
How reliable is the head and shoulders?
