What is Hammer?

Bolg'a (hammer)

In short

A small-bodied candle with a long lower wick. After a decline it shows buyers pushed price back up.

Also known as: bolg'a

A hammer is a candle with a small body, a long lower wick and a very short or missing upper wick. It only counts as a hammer when it appears after a decline. What it says: during the period sellers drove price well lower, but buyers pushed it back and it closed near the open.

Typical criteria

  • The lower wick is at least twice the length of the body.
  • The body sits in the upper part of the range.
  • The upper wick is tiny.
  • The body can be green or red; a green one is considered slightly stronger.

How it is used

A hammer signals a possible reversal, not a guaranteed one. Many traders wait for confirmation: the next candle should close above the hammer's high. A hammer that forms at a support level on above-average volume is a stronger signal. The stop is usually placed just below the low of the hammer's wick.

Don't mix it up

The same shape after a rally is called a hanging man and is read differently. The mirror version with the long wick on top is the inverted hammer.

Both candles look almost the same: a small body and a long lower wick. At the end of a decline, at support, it is a hammer (the next candle rose to $104.10 and confirmed it). At the end of a rally, at resistance, it is a hanging man (the next candle closed at $108.50, below its low).

Example

Illustrative case: a stock falls from $60 to $50 over two weeks. The next daily candle opens at $50.40, drops to a low of $48.00, closes at $50.80, with a high of $51.00.

  • Body: $50.80 − $50.40 = $0.40 (green).
  • Lower wick: $50.40 − $48.00 = $2.40 — six times the body.
  • Upper wick: $51.00 − $50.80 = $0.20.

The next day closes at $51.20, above the hammer's high — confirmation. With an entry at $51.20 and a stop at $47.90 (below the wick), the risk per share is $3.30. On a $10,000 account risking 1% ($100): 100 ÷ 3.30 ≈ 30.3 → 30 shares. You can check this with the position size calculator.

Mistakes and tips

  • Only look for hammers after a decline — the same candle in the middle of a rally or a range means something else.

  • Entering without confirmation is a common mistake: after many hammers the decline simply continues.

  • A very long lower wick pushes the stop further away, so shrink your position size to match.

Frequently asked questions

Does a red hammer candle still count?
Yes — colour isn't the main criterion, the shape is. A green hammer is considered a bit stronger because price closed above the open.
What is the difference between a hammer and a pin bar?
Pin bar is a general name for a candle with a long wick in either direction. A hammer is the specific version with a long lower wick that appears after a decline.
