Hammer candlestick: what the long lower tail tells you

A hammer is a candle with a small body near the top and a long tail hanging below. It tells a short story about one round of the fight, and it only matters in the right place.

The exact shape

A hammer is one candlestick with three features:

• A small body near the top of the candle. Green or red both count.
• A long lower tail (the wick) at least about 2 times the length of the body.
• Little or no upper tail.

It forms after price has been falling. That part matters. The same shape after a rise has a different name (more on that below).

A hammer in numbers

Here's an example candle on a daily chart:

Now measure it:

• Body: 100.80 − 100.00 = 0.80.
• Lower tail: 100.00 − 96.00 = 4.00. That's 5 times the body.
• Upper tail: 101.00 − 100.80 = 0.20. Tiny.

That's a clean hammer. The body sits in the top fifth of the candle, and the tail does most of the talking.

What it says about buyers and sellers

Read the candle as a story, from open to close.

1. The day opened at 100.00.
2. Sellers pushed price all the way down to 96.00.
3. Then buyers stepped in and pushed it right back up.
4. By the close, price was back near the top, at 100.80.

So sellers had control for part of the day, and lost it. The long tail is the footprint of that rejection. In plain words: price went looking lower, and it didn't like what it found.

But it's one round. A hammer doesn't say the fall is over. It says buyers showed up once.

Where a hammer matters

Location beats shape. We covered this in candlestick patterns for beginners, and it's even more true for hammers, because long tails are common.

A hammer is worth your attention when:

• It sits on a floor. A support zone where price turned up before, or a demand zone (see supply and demand zones).
• The tail pokes into that zone and the body closes back above it.
• The bigger chart agrees. A hammer at a floor in an uptrend, after a pullback, has the wind behind it. Check the bigger trend first with multiple timeframe analysis.

A hammer in the middle of a range, far from any level, is just a candle with a long tail.

Confirmation: wait for the next body close

The hammer is a hint, not a signal. We want proof that buyers kept going.

The test: the next candle's body closes above the hammer's high.

In our example, that means a body close above 101.00. A wick that pokes above 101.00 and falls back doesn't count. Only the body close does.

Waiting costs a little price. It also filters out hammers that were just a pause in a longer fall.

Where the stop goes

The chart tells you where you're wrong. For a hammer, that's below the low of the tail.

If price goes back under 96.00, the buyers who made that tail are gone. The story is over.

Most traders add a little room under the low, so normal noise doesn't knock them out. Then work out the size:

• Say you enter on the confirmation close at 101.20.
• Stop at 95.80, just under the tail.
• Stop distance: 5.40 per share.

Long tails mean wide stops. A wide stop means a smaller position, so the loss stays the same slice of your account. The position size calculator does that math for you. More on placing stops: how to set a stop loss.

When a hammer fails

It fails often. That's why the stop comes first.

Failure usually looks like this: the next candle closes below the hammer's body, then price slides back to the tail's low and through it. Sellers simply came back stronger. Big news, a weak bigger trend, or a floor that has been tested too many times can all do it.

Hammer vs its look-alikes

All four are members of the pin bar family: one long tail, small body.

Common mistakes

• Calling it before the close. A candle with a long tail at noon can close as a big red candle. Judge it only once it's closed.
• Ignoring where it is. A hammer in the middle of nowhere says very little.
• Using a fixed share size. The tail decides the stop, and the stop decides the size.
• Chasing a late entry. If the confirmation candle is huge, your stop is now far away. It's fine to skip it.

Try it today

1. Open a daily chart on TradingView and mark 2 or 3 floors where price turned up before.
2. Start bar replay a few months back. Never peek ahead.
3. Each time a hammer forms, write down: Is it at a floor? Did the next body close above its high?
4. Log 10 of them in a trading journal. Note which ones held and which failed.

You'll start to see that the place matters more than the candle.
