A Hammer is a single-candle bullish reversal with a small body near the top and a long lower wick at least twice the body. It shows that sellers pushed price down but buyers reclaimed control by the close — a sign a downtrend may be exhausting.

It forms after a decline: price sells off sharply within the candle, then rallies to close near the open, leaving a long lower shadow and little or no upper wick. Colour matters less than the shape, though a green hammer is marginally stronger.
Traders look for confirmation — a green candle or a close above the hammer’s high — before going long, with a stop below the wick. It works best at established support after a clear down-move.

A hammer means buyers rejected lower prices within the candle, hinting at a potential bottom. It is a reversal signal that gains strength at support and with confirmation on the next candle.
They look identical — small body, long lower wick — but context flips the meaning: a hammer appears after a downtrend (bullish), while a hanging man appears after an uptrend (bearish).
