Candlestick patterns are specific formations of one, two, or three consecutive candles that have historically signaled changes in market direction or momentum. Originating from 18th-century Japanese rice trading and formalized for Western audiences by Steve Nison, candlestick analysis remains one of the most widely practiced forms of technical analysis.
Unlike chart patterns that form over days or weeks, candlestick patterns form over just one to three periods. This makes them particularly useful for timing entries and exits, confirming (or rejecting) signals from longer-term analysis.
A critical principle to establish at the outset: context matters more than the pattern name. A hammer at a major support level after a prolonged downtrend is a meaningful signal. The same candle shape in the middle of a sideways range with no structural significance is just noise. Candlestick patterns derive their power from where they appear, not merely from what they look like.
Single Candle Patterns
Single candle patterns are the building blocks of candlestick analysis. They tell you about the balance of power between buyers and sellers within one period.
Marubozu
Doji
A doji forms when the open and close are virtually identical, creating a candle with a very small or nonexistent body. The wicks can vary in length, and these variations create different doji types, each with slightly different implications:
- Standard doji: Small body with roughly equal upper and lower wicks. Signals indecision, neither buyers nor sellers won the period.
- Long-legged doji: Very long upper and lower wicks with a tiny body in the middle. Extreme indecision with wide-ranging price action that ultimately went nowhere.
- Gravestone doji: No lower wick (or negligible), long upper wick. Price rallied during the period but sellers drove it all the way back to the open. Bearish signal, especially at resistance levels.
- Dragonfly doji: No upper wick (or negligible), long lower wick. Price fell during the period but buyers drove it all the way back to the open. Bullish signal, especially at support levels.
A doji in isolation means little. Its significance comes from context: a doji after a strong trend suggests potential exhaustion or reversal, particularly when it appears at a key support or resistance level.
Hammer
The hammer has a small body at the upper end of the candle and a long lower wick, typically at least twice the length of the body. There is little to no upper wick. The color of the body (bullish or bearish) is secondary to the shape.
Signal: Bullish reversal when it appears after a downtrend. The long lower wick shows that sellers pushed price down significantly during the period, but buyers recovered most or all of the ground, a sign of rejection of lower prices.
Bulkowski's research indicates that hammers acting as bullish reversals have a reversal rate of approximately 60%, making them moderately reliable when confirmed by the following candle closing above the hammer's high.
Inverted Hammer
The mirror image of the hammer, a small body at the lower end with a long upper wick and little to no lower wick. It appears at the bottom of a downtrend.
Signal: Potential bullish reversal. The interpretation is less intuitive: the long upper wick shows that buyers attempted to push price up but were initially rejected. However, the fact that they tried at all, after a sustained downtrend, suggests that selling pressure may be weakening. Confirmation (a bullish close on the next candle) is essential.
Shooting Star
The shooting star looks identical to an inverted hammer but appears at the top of an uptrend. Small body near the low of the candle, long upper wick, little to no lower wick.
Signal: Bearish reversal. Buyers pushed price to new highs during the period, but sellers drove it all the way back down by the close. This rejection of higher prices at the top of an uptrend is a warning that the buying momentum may be exhausting.
Spinning Top
A spinning top has a small body in the middle of the candle with upper and lower wicks of moderate length. It signals indecision, similar to a doji but with a slightly larger body. Spinning tops are less significant than dojis but still indicate uncertainty, especially after extended trends.
Double Candle Patterns
Double patterns involve two consecutive candles and often provide stronger signals than single patterns because they show a shift in momentum from one period to the next.
Bullish and Bearish Engulfing
For an engulfing pattern to be significant:
- It should appear after a definable trend (at least several candles of directional movement).
- The engulfing candle should have a notably larger body than the previous candle.
- The higher the timeframe, the more reliable the signal.
- Appearance at a key support or resistance level significantly increases reliability.
Harami (Inside Bar)
A harami is the opposite of an engulfing pattern, the second candle's body is entirely contained within the body of the first candle. The name comes from the Japanese word for "pregnant."
- Bullish harami: A large bearish candle followed by a smaller bullish candle contained within it. Suggests the selling momentum has stalled.
- Bearish harami: A large bullish candle followed by a smaller bearish candle contained within it. Suggests the buying momentum has stalled.
Haramis are less powerful than engulfing patterns because they show a pause rather than an aggressive takeover. They require confirmation from the next candle.
Tweezer Tops and Bottoms
Tweezer patterns consist of two candles with matching highs (tweezer top) or matching lows (tweezer bottom):
- Tweezer top: Two consecutive candles at the top of an uptrend with nearly identical highs. The first candle is bullish, the second bearish. The identical highs suggest a precise resistance level where sellers are stepping in.
- Tweezer bottom: Two consecutive candles at the bottom of a downtrend with nearly identical lows. The first candle is bearish, the second bullish. The identical lows suggest a precise support level where buyers are stepping in.
The matching highs or lows create a mini double-top or double-bottom formation within just two candles.
Triple Candle Patterns
Triple patterns are the most complex candlestick formations. They take three periods to form and often provide the strongest reversal signals.
Morning Star and Evening Star
Bulkowski's research on the evening star shows it is a moderately reliable bearish reversal signal, with an average decline of approximately 3.3% in equities. The morning star shows a comparable average rise. Performance improves significantly when these patterns appear at established support or resistance levels.
Three White Soldiers and Three Black Crows
- Three white soldiers: Three consecutive bullish candles, each opening within the body of the previous candle and closing near its high. Each candle should have a full body with small or no upper wicks. This pattern indicates strong, sustained buying pressure and is a bullish continuation or reversal signal.
- Three black crows: Three consecutive bearish candles, each opening within the body of the previous candle and closing near its low. This is the bearish counterpart, indicating strong, sustained selling pressure.
These patterns are most meaningful when they appear at significant price levels, three white soldiers bouncing off a major support level, for example, is a powerful signal.
Context Is Everything
The single most important principle in candlestick analysis is that the context in which a pattern appears determines its significance far more than the pattern itself.
A hammer at the bottom of a six-month downtrend, right at a weekly support level, with RSI showing oversold divergence, is a high-probability reversal signal. The same hammer shape in the middle of a choppy range, far from any significant level, is meaningless.
When evaluating any candlestick pattern, ask:
- Is there an existing trend to reverse? Reversal patterns require a prior trend. Without one, the pattern has nothing to reverse.
- Is the pattern at a significant level? Support, resistance, trend line, moving average, round number, the more factors that align at the pattern's location, the more significant it is.
- What does the higher timeframe show? A bullish engulfing on the H1 chart means little if the daily chart is in a strong downtrend with no support in sight.
- Is volume supporting the signal? Increasing volume on the signal candle adds confirmation.
- Is there confirmation? The candle following the pattern should confirm the expected direction. A hammer followed by a bearish candle that closes below the hammer's low negates the signal.
Bulkowski Reliability Data
Thomas Bulkowski, in his Encyclopedia of Candlestick Charts, tested dozens of candlestick patterns across thousands of historical examples. Some notable findings:
| Pattern | Type | Reversal Rate | Reliability Rating |
|---|---|---|---|
| Bearish engulfing | Bearish reversal | ~79% | High |
| Bullish engulfing | Bullish reversal | ~63% | Moderate |
| Hammer | Bullish reversal | ~60% | Moderate |
| Shooting star | Bearish reversal | ~59% | Moderate |
| Morning star | Bullish reversal | ~78% | High |
| Evening star | Bearish reversal | ~72% | High |
| Three black crows | Bearish reversal | ~78% | High |
| Doji (in uptrend) | Bearish reversal | ~51% | Low |
These statistics underscore an important point: no candlestick pattern is a guaranteed signal. Even the best-performing patterns fail 20-40% of the time. This is why candlestick patterns should never be traded in isolation, they are confirmation tools, not standalone strategies.
Common Mistakes in Candlestick Analysis
Memorizing names without understanding context. Knowing the name "hammer" is worthless if you cannot assess whether its location and market context make it significant.
Trading patterns in isolation. A single candlestick pattern without supporting context (S/R levels, trend direction, higher timeframe alignment) is no better than a coin flip.
Ignoring the candle close. A candle is not a pattern until it closes. A hammer that is forming on a live chart may turn into a full-body bearish candle by the time the period ends. Always wait for the close.
Seeing patterns everywhere. Confirmation bias leads traders to see hammers and engulfing patterns at every turn. Limit your analysis to patterns that appear at pre-identified levels and within clear market structures.
Expecting exact textbook formations. Real market candles are messy. An engulfing candle may not perfectly cover the prior body to the pip. Use the spirit of the pattern, a strong momentum shift, rather than demanding pixel-perfect textbook formations.
Key Takeaways
- Candlestick patterns are one-to-three candle formations that signal shifts in buyer/seller dynamics within short timeframes.
- Single candle patterns (doji, hammer, shooting star, marubozu) show intra-period sentiment. They require contextual confirmation.
- Double candle patterns (engulfing, harami, tweezer) show momentum shifts between two consecutive periods. Engulfing patterns are among the most reliable.
- Triple candle patterns (morning/evening star, three white soldiers/three black crows) tell a three-act story of sentiment change and provide the strongest signals.
- Context determines significance. A pattern's location relative to support/resistance, the prevailing trend, and the higher timeframe is far more important than the pattern name.
- Bulkowski's statistical data provides empirical performance metrics, bearish engulfing (~79% reversal rate) and morning star (~78%) are among the highest performers.
- No pattern is a standalone strategy. Use candlestick patterns as confirmation tools within a broader analytical framework.
- Always wait for the candle to close before identifying a pattern. Incomplete candles can change shape dramatically.
