Pin Bar Candlestick: Valid Rejection or Just a Wick?

Measure the wick before you name the candle

A 4-hour candle has just closed with a long tail into support at 30.4. It ran from a high of 31.9 to a low of 30.1, opened at 31.55 and closed at 31.7. The tail is obvious. Whether it counts depends on three measurements, and each one comes straight off the price axis.

Rule one: the wick covers at least two thirds of the full range. The range is 31.9 minus 30.1, which is 1.8. The lower wick runs from the bottom of the body at 31.55 down to 30.1, which is 1.45. Divide 1.45 by 1.8 and you get 81%, well above the 67% line. Pass.

Rule two: the body sits inside the third of the range opposite the wick. The top third of this candle starts at 31.9 minus 0.6, or 31.3. The body runs from 31.55 to 31.7, entirely above that line. Pass. A body that straddles the middle of the range makes the candle a spinning top, however long the tail.

Rule three: the wick pierces a level and the close is back on the original side. The low at 30.1 is 0.3 below the 30.4 support, and the close at 31.7 is 1.3 above it. Pass. Without the level, rules one and two only describe a shape, and the strip in the diagram holds a candle that passes both and still fails.

These thresholds are stricter than the classic candlestick rule. StockCharts’ Introduction to Candlesticks asks for a shadow at least twice the length of the real body for a hammer or a shooting star. Twice the body is a weak filter on its own: a candle with a 20% body, a 40% upper shadow and a 40% lower shadow passes it and is plainly a spinning top. The two-thirds rule and the opposite-third rule shut that door.

Five candles, three pass, two fail

Rules are easier to trust once you watch them reject something. The right half of the diagram holds five 4-hour candles, A to E, drawn against the same support at 30.4 and a resistance at 32.0. Each gets the three measurements. A and B are the textbook cases, C is the one a color filter throws away, and D and E show the two ways a long wick fails.

• A: range 30.15 to 31.15, body 31.0 to 31.1, lower wick 0.85 of 1.0, low through 30.4.
• B: range 31.25 to 32.3, body 31.3 to 31.4, upper wick 0.9 of 1.05, high through 32.0.
• C: range 30.2 to 31.15, body 30.95 to 31.05 with a down close, lower wick 0.75 of 0.95, low through 30.4.
• D: range 30.2 to 31.3, body 30.85 to 30.9, lower wick 0.65 of 1.1, low through 30.4.
• E: range 30.7 to 31.6, body 31.45 to 31.55, lower wick 0.75 of 0.9, no level within reach.

Candle C closes 0.1 below its open and still passes. Body color is not one of the three rules. StockCharts describes the hammer as white or black, and the rejection lives in the wick, which reads the same on either color. A filter that demands a green body discards C for a reason the rules do not recognize.

D has a long tail and fails twice: 59% is short of two thirds, and its body sits below 30.93, in the middle of the range. E measures like A, with an 83% wick and a body in the top third, and it is still noise. Its low at 30.7 is 0.3 above the support and its high at 31.6 is 0.4 below the resistance. Nothing was pierced, so nothing was rejected.

Enter above the high, stop below the low, then check the room

The simplest pin bar trading strategy uses the candle’s own extremes. For the bullish example, the long entry is a buy stop at 31.95, 0.05 above the high of 31.9, and the protective stop sits at 30.05, 0.05 below the low of 30.1. Risk per unit is 31.95 minus 30.05, which is 1.9.

The target is the earlier 4-hour swing high at 35.75. That is 3.8 above the entry, and 3.8 divided by 1.9 is 2.0, so the plan risks one unit to make two. Had the nearest resistance sat at 33.5 instead, the reward would have been 1.55, the ratio about 0.8, and the same valid candle would not have been worth an order.

Two conditions kill the setup before it starts. If the next candle closes below 30.1, the low has been taken and the rejection failed, whatever the measurements said. If price has not traded through 31.95 within the next two 4-hour candles, the order is stale. Cancel it. Chasing the same idea at 32.4 turns a 2R plan into a 1.4R plan with the same stop.

Some traders enter at the midpoint of the candle instead, at 31.0 here, which cuts the risk to 0.95 and lifts the ratio to 5.0 on the same target. The cost is fill risk. If price never comes back to 31.0, there is no trade, and the 2R version at 31.95 has already left. Pick one entry rule and write it down before the next candle opens.

This page grades the candle and shows the arithmetic of one plan. It does not tell you whether to place the order.

Pin bar vs hammer: one candle, two naming systems

A bullish pin bar at support and a hammer after a decline are the same candle. Nison’s Japanese Candlestick Charting Techniques names the shape by what came before it: a long lower shadow after a decline is a hammer, the same shape after an advance is a hanging man, and a long upper shadow after an advance is a shooting star. The price-action vocabulary uses one word and lets the level do the naming.

The measurements differ as well. StockCharts’ bullish reversal page asks for a lower shadow at least twice the body, a small or nonexistent upper shadow, and then confirmation: a gap up, a long white candle or a high-volume advance. The two-thirds rule is tighter on shape, and the pierced level stands in for the prior trend.

The bearish reversal page adds a check the pin bar rules leave implicit: the high-to-low range itself should be relatively large. A candle with a range of 0.4 on a chart whose 4-hour candles run about 1.2 passes both ratios and still says little. Compare the range with the last ten to twenty candles before you grade the wick.

The label adds nothing to the measurement. Pin bar is the price-action community’s name for the same family Nison filed under hammer, hanging man and shooting star, and the chart does not care which word you use. What the word tends to hide is the location rule. A pin bar in the middle of a range, like candle E, is noise with a good shape, and no vocabulary changes that.

For the two lower-wick names and how the prior move separates them, read the hammer versus hanging man guide. For candles whose open and close nearly match, the doji guide takes over; a dragonfly doji with a long lower shadow sits close to a pin bar, and the difference is the body.

Check the level before you trust the wick on a screenshot

A pin bar at support is only as good as the support. Mark the level first and count the earlier turns at it; the example treats 30.4 as a level that had already held on the same 4-hour chart. A line touched once is a guess. The support and resistance page covers how levels are read from a screenshot and rated.

Candle boundaries move between platforms. MetaTrader brokers set their own server time, and many crypto exchanges cut 4-hour candles at 00:00 UTC, so the same move can print as one pin bar on one feed and as two ordinary candles on another. Keep the symbol, the timeframe and a legible price axis in the image, as the chart screenshot checklist lays out, so the wick can be measured rather than guessed.

On your own chart, check the three numbers by hand: wick share, body position and the level the wick crossed. TradeGPT reads the same screenshot and reports key levels with a strength rating and a distance from price, lists candle signals under Patterns & Signals, and, where a plan is warranted, gives an entry, a stop loss, take profits and an invalidation condition.

Start with the sample report to see how those sections are laid out, then analyze your chart. Crop account balances and order panels first, because the whole image is what gets uploaded.

Questions traders ask about pin bars

What is the pin bar candlestick pattern?

A single candle with one long wick and a small body pushed to the far end of the range, printed at a level the wick pierced and the close abandoned. The name comes from the price-action community; Nison’s vocabulary calls the same shapes hammer, hanging man and shooting star. The wick is the whole signal.

How do you identify a valid pin bar?

Measure three things. The wick covers at least two thirds of the high-to-low range. The body sits inside the opposite third. The wick pierces a level you marked before the candle printed, and the close is back on the far side. In the example, 1.45 of 1.8 is 81%, the body sits above 31.3, and the low cut through 30.4.

What is the difference between a pin bar and a doji?

Body size. A doji’s open and close are virtually equal, in StockCharts’ definition, so the candle says buyers and sellers finished level. A pin bar has a small but real body, 0.15 on a range of 1.8 in the example, pressed against one end. Grade a long-shadowed doji by the level it pierced, the same way.

Is a pin bar bullish or bearish?

The wick decides. A long lower wick that pierced support and closed back above it is a bullish pin bar. A long upper wick that pierced resistance and closed back below it is a bearish pin bar. Body color is secondary: candle C in the diagram closes down and still grades as a valid bullish signal.
