Most candlestick guides hand you a wall of shapes and walk away. Here is a hammer, here is a doji, here is an engulfing, good luck. The problem is that a candle by itself tells you almost nothing about whether to trade it. The same hammer is an A-grade setup at support in an uptrend and a nothing-candle in the middle of a flat range, and the cheat sheet never mentions that. This guide covers every major pattern worth knowing, what each one looks like, and what it signals. But the part that actually matters, the part the cheat sheets skip, is context: where the candle sits in the trend, whether it printed at a level, and whether volume backs it. That context is exactly what AI grades off a screenshot, which is the difference between knowing that is a hammer and knowing that is a tradeable hammer.

Quick Answer

In one paragraph

Candlestick patterns are shapes formed by one or more price bars that show who won the fight between buyers and sellers inside those bars. They fall into three families: bullish reversal patterns (hammer, engulfing, morning star) that hint a downtrend is turning up, bearish reversal patterns (shooting star, engulfing, evening star) that hint an uptrend is turning down, and indecision candles (doji, spinning top) that show neither side won. The single most important thing to understand is that a pattern only matters in context. The same candle means opposite things depending on where it sits in the trend, whether it printed at a support or resistance level, and whether volume backs it. That context, location plus volume, is what decides whether a pattern is tradeable, and it is exactly what AI grades when you upload the chart.

What Are Candlestick Patterns?

A candlestick shows four prices for one period: the open, the high, the low, and the close. The body is the distance between the open and the close, and the thin lines above and below it, the wicks, mark the high and low. A green (or hollow) body means price closed above where it opened, buyers won the bar. A red (or filled) body means it closed below the open, sellers won. The wicks tell you where price tried to go and got rejected. Investopedia's reference on the candlestick chart lays out that anatomy in detail, and it is worth getting comfortable with before any pattern names. If you are still building the base layer, the guide on how to read stock charts walks through candle anatomy alongside the rest of the chart.

A candlestick pattern is just one candle, or a small cluster of them, whose shape carries a recognizable meaning. A long lower wick says sellers pushed price down and buyers slammed it back. A body that swallows the previous bar says one side took control in a single session. Patterns get grouped by what they tend to signal: reversal patterns that hint a trend is about to change direction, indecision candles that show a standoff, and continuation patterns that say the current trend is just catching its breath. The names come from centuries of Japanese rice traders, but the logic underneath is simple supply and demand printed as shapes.

The trap is reading the shape and stopping there. A pattern is a sentence about one moment of price action, not a forecast. The hammer tells you buyers won a single bar after a flush, it does not tell you the downtrend is over. What turns that hint into a real signal is everything around the candle: the trend it printed inside, the level it printed at, and the volume behind it. A hammer right at a tested support line, ending a clean downtrend, on a fat volume bar, is a setup. The identical hammer floating in the middle of a sideways range, on average volume, is noise. Same shape, opposite trade. That gap between shape and context is the entire reason this guide exists, and it runs through every section below.

What Are the Bullish Reversal Patterns?

Bullish reversal patterns show up after a decline and hint that buyers are stepping back in. They range from single candles like the hammer to two-bar shifts like the engulfing to three-bar formations like the morning star. The thread across all of them is the same: a bullish reversal candle only carries weight when it prints at support, in line with a higher-timeframe turn, with volume behind it. The table below is the cheat-sheet version, with the context column doing the work the typical cheat sheet leaves out.

Bullish reversal patterns at a glance
context is the column that matters
PatternWhat it looks likeWhat it signalsKey context
HammerSmall body up top, long lower wick at least twice the body, little or no upper wickSellers pushed price down hard, buyers reclaimed it by the close, a bottoming tailOnly counts at support after a downtrend or pullback, best with a volume bump on the reclaim
Inverted hammerSmall body down low, long upper wick, little or no lower wick, after a declineBuyers tried to push up and got faded, but the attempt itself hints the bottom is nearNeeds confirmation from the next candle, weak on its own, stronger at a tested level
Bullish engulfingA green body that fully swallows the prior red body, opening lower and closing above itBuyers took complete control in one bar, a decisive shift from the selling before itStrongest at support ending a downtrend, on volume bigger than the candles around it
Piercing lineRed candle, then a green candle that opens below the low and closes past the red midpointA near-reversal, buyers clawed back more than half the prior day's lossA weaker cousin of the engulfing, wants a level and volume to be worth acting on
Morning starBig red candle, a small-bodied candle (the star), then a big green candle closing highSelling, then indecision, then buyers taking over, a classic three-bar bottomBest at the end of a clear downtrend at support, the green bar should close strong
Three white soldiersThree tall green candles in a row, each opening within the prior body and closing higherSteady, broad buying pressure, momentum building rather than one violent spikeMost meaningful off a base or after a downtrend, watch for it to be overextended late
Bullish haramiA large red candle, then a small green candle contained inside the prior bodySelling momentum stalled, the small inside bar is the pause before a possible turnA heads-up, not a trigger, weak alone, wants confirmation and a level to mean anything

The two that earn the most attention are the hammer and the bullish engulfing, because both pack a decisive shift into a clear shape. Investopedia's breakdown of the hammer candlestick is a good companion reference. A hammer is a tail of rejected selling, and it only means anything at the bottom of a move where that rejection matters. The engulfing is even more direct: when a green bar fully swallows the prior red one at support, buyers did not just nudge price, they took the whole bar back in one session. That is a stronger statement than a wick. The morning star is the three-bar telling of the same story, selling then a pause then buying, and the same rule applies: it is a setup at the end of a downtrend at a level, and a curiosity anywhere else.

What Are the Bearish Reversal Patterns?

Bearish reversal patterns are the mirror image. They print after an advance and hint that sellers are taking over, and they carry weight only at resistance, in line with a higher-timeframe turn down, with volume behind the rejection. The shapes line up almost one to one with the bullish set: the shooting star mirrors the hammer, the hanging man mirrors the hammer in a different location, the bearish engulfing mirrors the bullish one, and the evening star mirrors the morning star. The table below is the bearish cheat sheet, same structure, same emphasis on context.

Bearish reversal patterns at a glance
location flips half of these
PatternWhat it looks likeWhat it signalsKey context
Shooting starSmall body down low, long upper wick at least twice the body, after an advanceBuyers pushed up and got rejected hard, sellers slammed it back by the closeOnly counts at resistance after an uptrend or rally, a volume spike makes it sharper
Hanging manSame shape as a hammer, small body and long lower wick, but printed after an uptrendSellers showed up intraday even though buyers recovered, an early warning at the topLocation flips the meaning, a hammer at a top is a hanging man, needs next-bar confirmation
Bearish engulfingA red body that fully swallows the prior green body, opening higher and closing below itSellers took complete control in one bar, a decisive shift after the buying before itStrongest at resistance ending an uptrend, on volume bigger than the candles around it
Dark cloud coverGreen candle, then a red candle opening above the high and closing past the green midpointA near-reversal, sellers erased more than half the prior day's gainThe bearish mirror of the piercing line, wants a level and volume behind it
Evening starBig green candle, a small-bodied star, then a big red candle closing lowBuying, then indecision, then sellers taking over, a classic three-bar topBest at the end of a clear uptrend at resistance, the red bar should close weak
Three black crowsThree tall red candles in a row, each opening within the prior body and closing lowerSteady, broad selling pressure, distribution rather than one panic candleMost meaningful off a top or after an uptrend, can be exhausted late in a flush
Bearish haramiA large green candle, then a small red candle contained inside the prior bodyBuying momentum stalled, the small inside bar is the pause before a possible turnA heads-up, not a trigger, weak alone, wants confirmation and a level to mean anything

The hammer and hanging man are the clearest lesson in why location is everything. They are the same candle, a small body with a long lower wick. After a downtrend at support, that wick is a hammer, a buying tail, bullish. After an uptrend at resistance, the identical wick is a hanging man, a warning that sellers showed up, bearish. The shape did not change at all. Only where it printed changed, and the meaning flipped with it. Investopedia's reference on the engulfing pattern makes the same point for the two-bar version. This is why naming the shape is the easy half and reading the context is the half that actually pays, the exact logic behind the broader chart patterns library where the same candle resolves differently depending on the structure it sits inside.

The Same Hammer, Two Locations, Two Grades

A hammer candlestick graded A-grade at support in an uptrend versus the same hammer graded a non-setup in the middle of a flat rangeOn the left, a hammer prints right at a support line at the end of a pullback inside an uptrend and price resumes higher, an A-grade location. On the right, the identical hammer prints in the middle of a flat sideways range at no level, a non-setup, and price keeps chopping.Hammer at support, A setupsupporthammerASame hammer mid-range, no setuprange toprange floorsame shapeC

Read the candle

What Do Doji and Indecision Candles Mean?

A doji forms when the open and close land at almost the same price, leaving a tiny or nonexistent body. It is the chart drawing a standoff: buyers and sellers fought all bar and finished even. By itself a doji is not bullish or bearish, it is a pause, a question mark. What gives it direction is the wicks and the location. The variants below split the doji family by where the long wick sits, because that is what flips a neutral standoff into a directional warning.

Doji and indecision candles
a pause, read with the level
CandleWhat it looks likeWhat it means
Doji (standard)Open and close almost equal, a tiny or nonexistent body with wicks on both sidesA standoff, neither buyers nor sellers won the bar, momentum may be stalling
Gravestone dojiOpen, close, and low near the bottom, one long upper wick, like an inverted TBuyers pushed up and got fully rejected, bearish near a top or resistance
Dragonfly dojiOpen, close, and high near the top, one long lower wick, like an upright TSellers pushed down and got fully reclaimed, bullish near a bottom or support
Long-legged dojiTiny body in the middle of long wicks on both sides, a wide range that went nowhereMaximum indecision and volatility, a coin-flip bar, often a pause before a move
Spinning topA small real body with upper and lower wicks of roughly similar lengthWeak conviction, neither side committed, a softer version of the doji standoff

The gravestone and dragonfly are the doji variants worth knowing cold because they behave like reversal candles when they land in the right spot. A gravestone doji, all upper wick, at resistance after a run, is buyers getting fully rejected, much like a shooting star. A dragonfly doji, all lower wick, at support after a flush, is sellers getting fully reclaimed, much like a hammer. The long-legged doji is the opposite, maximum indecision, a wide bar that traveled in both directions and settled nowhere. Where indecision candles really earn their keep is inside a tightening structure, where a string of small-bodied candles signals a market coiling before it picks a direction, the same read that drives the AI Bollinger Band squeeze setup. A doji at the top of an extended move is a far louder warning than a doji in the middle of a quiet drift, which is, again, context doing all the work.

What Are the Continuation Patterns?

Not every candle is about reversal. Continuation candles say the current trend is still in charge and just pausing. The cleanest is the marubozu, a candle with a full body and little or no wick on either end. A green marubozu means buyers controlled the bar from open to close with no pushback, raw conviction in the trend's direction. A red marubozu is the same for sellers. It is the opposite of a doji: instead of a standoff, one side ran the whole bar.

The rising and falling three methods are the multi-bar versions. A rising three methods is a big green candle, then a few small red candles that pull back without breaking the green candle's range, then another big green candle pushing to new highs. It is a pause inside an uptrend, the trend catching its breath before the next leg. The falling three methods is the bearish mirror in a downtrend. The shape rhymes hard with the price patterns momentum traders already trade: the small pullback candles inside a continuation are the candle-level version of the consolidation in a bull flag pattern, and the breakout candle that resumes the trend is the same event as a flag breakout. The same continuation logic carries the longer cup and handle pattern, where the handle is a controlled pause before price resumes higher. Whether you call it a three methods, a flag, or a handle, the read is identical: the trend paused, conviction returned, and the resumption candle is where the participation shows up.

How Does AI Grade a Candlestick Pattern?

Here is the differentiator, and it is the whole reason this guide is more than a shape chart. Naming a candle is the easy part. A cheat sheet does that, and so does your eye after a week of practice. The hard part, the part bias ruins, is deciding whether the candle in front of you is actually tradeable. That is a context question, not a shape question, and it is exactly what AI grades when you upload a screenshot. It reads the candle shape, then reads where that candle sits relative to the trend and the levels on the chart, then checks whether the volume bars back the move, and folds all of it into one A-to-F setup grade. The output is not that is a hammer. It is that is a B-plus hammer at support with confirming volume, or that is a C-grade hammer floating mid-range with nothing behind it.

The three context checks are the same ones a careful trader runs by hand. First, location in the trend: a bullish reversal candle after a clean downtrend or pullback is worth something, the identical candle mid-chop is not. Second, the level: a candle printing right at a tested support or resistance line carries weight a candle in open space does not, which is why the support and resistance levels on the chart are half the grade. Third, volume: an engulfing bar on volume bigger than the candles around it has real participation behind it, the same engulfing on quiet volume is a shrug, the read covered in depth in the AI volume analysis guide. Stack those three and you get a grade instead of a guess. The shape is one input. The grade is the verdict.

The honest limits matter as much as the read, because a tool that oversells itself is worse than no tool. The grade is read off one static screenshot, so it does not predict the next candle, it reads the one in front of it. It does not see live order flow, time and sales, or Level 2, because none of that lives in a still image, and a pattern is never a guarantee no matter how clean it looks. What it does well is the thing you are biased on: telling you the hammer you already decided to buy is sitting in the wrong location with no volume, so it is a C, not the A you wanted. If you want the shape-recognition side specifically, the AI candlestick pattern detector post covers how the detection works, and this grading layer is what sits on top of it. For the broader case that a candle should never be read in isolation, the same discipline runs through any AI chart analysis of a full setup, and you can see a neutral walkthrough of where candlestick reading fits on the candlestick pattern analysis page.

What Are the Most Common Mistakes?

Almost every candlestick mistake is a version of reading the shape without the context. Here are the ones that cost the most, and the read that fixes each.

  • No location
    Trading a hammer or engulfing in the middle of a range because the shape was textbook. A reversal candle with nothing to reverse is just a candle. The pattern only counts at a level, in line with a trend.
  • Ignoring volume
    Acting on a pretty engulfing bar that printed on quiet volume. Without participation behind it, a decisive-looking candle is a few orders, not a real shift. Want the volume bigger than the bars around it.
  • One candle, no confirm
    Jumping on a single inverted hammer or harami that explicitly wants the next bar to confirm. The weaker patterns are heads-ups, not triggers. Let the following candle agree before you commit.
  • Memorizing forty names
    Drowning in obscure three-candle patterns instead of mastering the handful that actually show up. Hammer, engulfing, star, doji, marubozu cover most real charts. The rare ones are a distraction.
  • Same shape, wrong location
    Forgetting that a hammer at a top is a hanging man and a doji means little in a drift. The shape is constant, the meaning is not. Read where it printed before you read what it is.

The fix for all five is the same habit: read the location and the volume before you read the name. A trader who looks at the trend and the level first, then asks what the candle is, takes far fewer of the pretty-shape-wrong-place trades that drain accounts. That habit is the core of the broader momentum trading strategy, where the entry candle only matters because of the structure it broke out of, and it is what a setup grade is built to enforce so your bias does not get a vote.

The point of grading the candle, not just naming it

You are not trying to predict the next bar from a shape. You are checking whether the candle in front of you printed in a location, with volume, that makes it worth trading. Let the AI read the trend, the level, and the volume around the candle and fold them into one grade, then take the setup only when the context backs the shape instead of fighting it. A textbook hammer in the middle of nowhere is a chart you scroll past, not a trade.

Frequently Asked Questions

Are candlestick patterns reliable?

Only in context, and anyone who tells you a candle is reliable on its own is selling you something. The exact same hammer is a strong signal at support in an uptrend and a meaningless wick in the middle of a choppy range. What makes a pattern reliable is everything around it: where it sits in the trend, whether it printed at a level that matters, and whether volume backs the move. A candlestick is a hint about who won the fight inside one bar, not a prediction of the next bar. Treat it as one input you weigh against structure and volume, and the hit rate gets a lot more honest. Treat it as a guarantee and you will get trapped, because the prettiest textbook candle in the wrong location is still a losing trade.

Which candlestick pattern is the most reliable?

If you forced a single answer, an engulfing candle or a hammer printed at a clear level with volume behind it is about as good as it gets, because those combine a decisive shift inside the bar with a location that other traders are watching. But that is the honest catch: none of them works alone. The reliability comes from the engulfing happening at support after a clean downtrend, on a volume bar bigger than the candles around it, not from the shape itself. A standalone engulfing in the middle of nowhere is no better than a coin flip. So the most reliable pattern is really the most reliable context, a strong reversal candle at a level, in line with the higher-timeframe trend, with participation.

How many candlestick patterns do I actually need to know?

Far fewer than the giant cheat sheets suggest. For day and swing trading you can cover most of what shows up with a short list: hammer and shooting star for single-bar reversals, bullish and bearish engulfing for two-bar shifts, morning star and evening star for the three-bar versions, the doji family for indecision, and marubozu for raw conviction. That handful covers the bulk of tradeable setups. Memorizing forty obscure three-candle names with Japanese titles is a distraction, because the rare ones barely show up and the common ones do the work. Learn the small set cold, learn to read them in context, and you have covered ninety percent of the real charts you will trade.

Do candlestick patterns work on every timeframe?

The shapes appear on every timeframe, but they are not equally meaningful. A hammer on a 1-minute chart is a much weaker signal than the same hammer on a daily, because one minute of price action involves far fewer participants and far more noise. The higher the timeframe, the more decisions are baked into the candle, so the pattern carries more weight. On fast intraday charts you get more patterns and more fakeouts, which is exactly why context matters more, not less. A candle on a 5-minute chart is worth taking seriously when it lines up with a level and the higher-timeframe trend, and worth ignoring when it is just one noisy bar in the chop.

Can AI tell me whether a candlestick pattern is tradeable?

That is the useful version of what AI does here, yes. It reads the candle shapes that are visible on the screenshot you upload, including hammers, engulfing bars, dojis, and stars, then grades them in context: where the candle sits relative to the trend, whether it printed at a support or resistance level, and whether the volume bars back the move. It folds that into an A-to-F setup grade instead of just naming the shape. The honest limits matter too. It reads one static picture, so it does not predict the next candle, does not see live order flow, time and sales, or Level 2, and a pattern is never a guarantee. What it does well is the part you are biased on: telling you that the hammer you like is sitting in the middle of a range with no volume, so it is a C, not the A you wanted it to be.
