Hammer and Hanging Man: One Shape, Two Conclusions
The hammer and the hanging man are the same candle by shape: a small body at the top and a long lower shadow. Only the location differs. In our EUR/USD sample the shape appeared 18 times, and the next day closed higher in 67% of cases against a base rate of 44%.
How the hammer is defined
The formal criteria: the lower shadow is at least twice the body, the upper shadow no larger than the body, and the body sits in the upper part of the candle's range. Body colour is irrelevant — geometry is what counts. After a decline the shape is called a hammer and read as bullish; after a rise it is a hanging man and read as bearish.
What happens inside the pattern
A long lower shadow means price travelled well below and returned by the close. Sellers pushed the market down and could not hold the result — buyers bought the move back entirely. At the end of a decline that suggests selling has exhausted itself. At the end of a rise the same picture reads differently: the market has shown for the first time that it is willing to fall, even if it recovered.
Entry and stop placement
Entry above the candle's high, stop below its low — that is, beyond the long shadow. This is the key practical detail: the stop is wide by definition because the shadow is long. Ignoring that and placing the stop closer guarantees being taken out. The correct answer to a wide stop is a smaller position, not tighter protection.
What the measurement showed
The formal definition was run over 400 daily bars of EUR/USD (2025-06-16 to 2026-07-20). Any result has to be compared against the sample's base rate of up days, which is 44%, not against half.
- Hammer / hanging man: 18 occurrences, next day closed higher in 67%
This shape produced the highest share of subsequent up days among all the patterns we tested. It also has the smallest sample: around two dozen cases. At that number the difference from the base rate proves nothing — this is precisely the sample size at which randomness looks most convincing.
Eighteen cases is the sample size at which a striking percentage means nothing. One or two trades going the other way would have shifted the figure by ten points. The figures describe one sample and one instrument rather than a property of the pattern in general — why that distinction matters is set out in our piece on sample size. The data is open and the method is in how we run backtests.
