Hammer candlestick

What a hammer candlestick is

A hammer candlestick is a single candle whose lower wick is long relative to its body, with the body sitting near the top of the candle's range and almost no wick above it. It records a period in which price traded well below the open and then recovered before the close.

The same formation appearing after a rise is conventionally called a hanging man instead. The name therefore describes a location as much as a shape.

What the shape actually records

A long lower wick means one thing that can be stated plainly: within that period, price went down and did not stay there. Nothing in the candle says who bought, how much they bought, or whether they are still there. Those are inferences layered on top of the only fact the candle contains.

This is where the proportions matter, and where the honest answer is uncomfortable. A wick at least twice the body is a widely used convention, and so are a body in the upper third of the range and an upper wick no more than a small fraction of the whole. None of these thresholds is established; they are conventions, and different sources use different ones. Two readers applying different conventions to the same chart will disagree about whether a given candle is a hammer at all.

That is not a detail to skip past. A pattern cannot be assessed until it has been defined precisely enough to be identified the same way every time. Until the thresholds are written down, whether something is a hammer is a question about the reader's own rule rather than about the market.

The anatomy: wick, body, close

Four measurements describe every candle in this family:

• The lower wick — the distance from the low to the bottom of the body — shows how far price fell within the period.
• The body — the distance between open and close — shows where the period settled relative to where it started.
• The upper wick — from the top of the body to the high — shows whether price was also rejected from above.
• The position of the body in the total range is what makes the shape a hammer rather than a doji.

The difference between a hammer and a hanging man

They are the same candle. Identical geometry: long lower wick, small body at the top, little or no upper wick. The names differ only by context. A hammer appears after a decline and is conventionally read as a possible pause or turn upward. A hanging man appears after a rise and is read as a possible pause or turn downward.

One shape, two opposite conventional readings, decided entirely by what came before it. This settles the question of whether the candle is bullish: the candle is not the signal, the location is. Anyone reading direction from the shape alone is reading something that is not there.

The related shapes, briefly, so they are not confused with it. An inverted hammer is the mirror image, with a long upper wick and the body near the bottom. A doji has open and close nearly equal, so there is no meaningful body. A shooting star is geometrically an inverted hammer after a rise, exactly as a hanging man is a hammer after a rise.

Where a hammer matters and where it does not

The conventional reading assumes the recovery within the period reflects buying interest that persists. That assumption is weaker in some conditions than others:

• Thin sessions. A long wick during a holiday or a session open can reflect an absence of participants rather than a rejection of price.
• Around scheduled news. A release repriced the instrument on new information; the wick records that repricing, not interest at a level.
• Inside a range. Long wicks are ordinary during consolidation, and treating each one as meaningful produces a signal on most candles, which is the same as no signal.
• On a timeframe you do not trade. A hammer on a one-minute chart and one on a weekly chart are not the same claim about anything.

Why a hammer alone is weak evidence

Three reasons, independent of each other. The shape is direction-neutral, as above. One period is a small sample, and it summarises a fixed interval chosen by the chart's settings rather than by the market. And the definition is discretionary: change the wick-to-body threshold and candles enter or leave the category.

Confirmation is the usual response — waiting for a subsequent close, a level, or another condition before acting. That is a reasonable habit, and it is worth being precise about why. Confirmation does not make the hammer stronger. It adds a second, independent piece of evidence. The hammer is exactly as weak as it was.

Common mistakes

Most of these are versions of reading more into one candle than it contains.

• Reading direction from the shape. The same candle is a hammer or a hanging man depending only on what preceded it.
• Having no written threshold, so the category expands and contracts to fit whatever the chart is doing.
• Counting only the hammers that worked, which describes the chart rather than the method.
• Acting on a hammer in isolation and then attributing the outcome to the pattern.
• Mixing timeframes without deciding in advance which one governs.

A review checklist

Written before the next trade, not after it. The last question is the only one that tests the rule rather than the intention.

• What is my wick-to-body threshold, as a number?
• Where must the body sit in the range, and how much upper wick do I allow?
• What counts as after a decline — how many periods, or what structure?
• Does a hammer alone trigger anything, or does it need a second condition?
• Which timeframe governs, and do I ignore the others?
• Reviewing my own hammer entries, did I apply these answers — or recognise the shape after the fact?
