Candlestick Patterns: Which Ones Actually Work?
Traders have named these shapes for two and a half centuries, and somewhere along the way naming them started to feel like predicting them. It isn't. Here is what the evidence says, including the awkward bit about the pattern everybody knows.
By Pavel Penev, MScFounder, TradeWize · 10+ years trading the marketsThe short answer
A candlestick pattern is a shape made of one to three candles that traders read as a signal — a doji for indecision, a hammer for a rejected low, an engulfing candle for a change of hands. They are genuinely useful as a description of what just happened. As a prediction of what happens next, the evidence is thin: academic tests found no tradeable edge in US or Japanese stocks across three decades, and even the practitioner who hand-checked more of these than anyone ranks the most famous pattern of the lot 84th out of 103.
A pattern is a sentence made of one to three candles
A single candle tells you four prices: where the session opened, how high it got, how low it got, and where it closed. A candlestick pattern is what you get when you stop reading one candle and start reading a short phrase of them — usually one, two or three in a row — and give that phrase a name.
The names are wonderful. Hammers, shooting stars, gravestones, hanging men, three white soldiers, the abandoned baby. Somewhere in eighteenth-century Japan a rice trader started this, and the vocabulary has been accumulating ever since, mostly unchecked, like a family recipe nobody has tasted in years.
| Pattern | Candles | What it looks like | What traders claim it means |
|---|---|---|---|
| Doji | 1 | Open and close in almost the same place, with wicks both ways. | Indecision — the tug-of-war ended level. |
| Hammer | 1 | A small body at the top, with a long lower wick and almost nothing above. | Sellers pushed it down all session and got rejected. |
| Shooting star | 1 | The hammer upside down: a long upper wick, body pinned near the low. | Buyers ran it up and lost the ground by the close. |
| Marubozu | 1 | All body, no wicks — it opened at the low and closed at the high. | One side owned the entire session. |
| Bullish engulfing | 2 | A down candle, then an up candle whose body swallows it whole. | The buyers took back everything yesterday's sellers won, and more. |
| Morning star | 3 | A big down candle, a small hesitant one below it, then a big up candle. | Selling, then doubt, then buying — a handover across three sessions. |
| Three white soldiers | 3 | Three long up candles in a row, each closing near its high. | A steady, determined advance. |
Learn these seven and you can read most of what anyone means by a candlestick pattern. The rest of the catalogue is largely variations on them.
That is the vocabulary, and it is worth having. A trader who says the daily printed a hammer at support has told you something specific and checkable in six words. The trouble starts at the next sentence, when the shape stops being a description and starts being a forecast.
So do they work? They spot turns. That is not the same thing.
Here is the awkward part, and it is awkward in an interesting direction. The patterns are not nonsense. Thomas Bulkowski has spent years hand-checking candlestick patterns across thousands of charts, and by his measurements most of them are followed by a reversal more often than not — the three white soldiers turns price 82% of the time, the morning star 78%, the bullish engulfing 63%. Those are not coin-flip numbers.
Except a reversal rate is a slippery thing to be impressed by. In a market that drifts upward over time, price goes up after a great many things, including nothing at all. A high reversal rate tells you the pattern is often followed by a turn; it does not tell you the pattern caused the turn, and it certainly does not tell you the turn was big enough to be worth trading. Those are three different claims, and the retail internet tends to collapse them into one.
The left column is uniformly encouraging. The right column — how the move that follows ranks against the other 102 patterns — is a mess. That gap is the whole argument.
Bulkowski himself is refreshingly blunt about this. Of the hammer, probably the single most-taught candle in existence, he notes that it reverses 60% of the time — "not far from random (50%)" — and that once it appears and price breaks out, "the move is unexciting." Of the shooting star: "this candle looks better than it performs," and day traders lean on it more than he thinks they should. This is a man who likes candlesticks.
The famous ones are the worst ones
Rank the patterns by what price does after them and something faintly comic emerges: fame and performance run in opposite directions. The shapes that made it onto every cheat sheet, every YouTube thumbnail and every broker's education tab are clustered in the wrong half of the table.
Bulkowski's overall performance rank across 103 candle patterns. The hammer is 65th. The bullish engulfing — the one every beginner learns second — is 84th.
The bullish engulfing is the one that really ought to give you pause. It turns price upward 63% of the time, which sounds like a strategy. It also ranks 84th of 103, because of what happens after the turn: by Bulkowski's numbers the best average move ten days after an upward breakout is a fall of 1.18%. Not a small gain. A fall. The pattern is frequently right about the direction and reliably useless about the trade, which is a very specific kind of trap — it hands you a win often enough to keep you doing it.
Meanwhile the morning star sits at 12th, comfortably the best of this group, and it is the one pattern here that nobody is selling you a course on. There is no obvious reason for that beyond the fact that "morning star" is harder to draw on a thumbnail than a big green candle eating a red one.
Learn it by doing
Reading about it is one thing — it clicks when you do it. Practise this hands-on in a free, interactive lesson (Stage 13: Active Investing: Should You Even Bother?).
Try the free lesson →“Doji” is a surname, not a verdict
The most-searched candlestick pattern is the doji, and the doji is not really a pattern. It is a family. A doji is any candle that opens and closes at roughly the same price, and depending on where the wicks go and what came before it, the same basic shape gets a different name and a wildly different record.
From the morning doji star at 25th to the gapping-up doji at 92th. Calling a candle "a doji" narrows things down about as much as calling someone "a Smith."
So when a chart prints a doji and somebody tells you the market is indecisive — fine, that is a fair description of a session that went nowhere. But the leap from there to what happens tomorrow depends entirely on which doji, after what, at which level. The name on its own is doing almost no work.
Your turn: find the pattern, then look at what happened next
Three charts. Each one has a named pattern hiding in it. Find it, tap it, and then — the part every cheat sheet leaves out — watch what price actually did over the following ten sessions.

If round two annoyed you, good. That is the bullish engulfing doing exactly what its rank says it does: turning, convincingly, and then handing the whole move back while you are still congratulating yourself.
What happened when researchers actually checked
Bulkowski's database is one careful practitioner's measurements. The academic record is separate, larger, and less kind.
In 2006, Marshall, Young and Rose tested candlestick strategies on Dow Jones component stocks over 1992 to 2002, using a bootstrap that generates random open, high, low and close prices to see whether the patterns beat chance. They did not. In 2008 the same lead author ran it on the largest 100 stocks on the Tokyo Stock Exchange — the market that invented the technique — across thirty years, 1975 to 2004. No evidence of value over the full period, none in any of three ten-year sub-periods, and none in bull markets or bear markets taken separately. That is a fairly comprehensive absence.
A 2017 study of Thailand's SET50 found the same thing in politer language: the mean returns of most candlestick reversal patterns were not statistically different from zero. Its one bright spot was the opening white marubozu, which managed between 0.13% and 0.71% — alongside a standard deviation of 8.04%, which is a way of saying the signal was a rounding error attached to a lot of noise.
It is not unanimous, and it would be dishonest to pretend it is. Lu, Shiu and Liu, publishing in 2012, tested two-day patterns on the components of Taiwan's Top 50 fund from 2002 to 2008 and found three bullish reversal patterns genuinely profitable — and they did the work, with out-of-sample testing and a bootstrap of their own. One credible positive result in one market over six years is not nothing. It is also not the foundation the cheat sheets imply.
What a candlestick pattern is actually for
None of this makes the shapes worthless. It makes them a vocabulary rather than a crystal ball, and a vocabulary is a genuinely useful thing to own. A hammer tells you sellers pushed price down through the session and lost the ground by the close. That happened. It is on the chart. Reading it costs you nothing.
What the evidence keeps suggesting is that the shape is the least important part of the setup. The same hammer is a different proposition at the bottom of a long decline, into a level price has turned at three times before, than it is in the middle of a quiet range — and it is the level, the trend and the context doing the work in that sentence, not the candle. That is why our guide to swing highs and lows spends its time on where price keeps stopping rather than on what the candles look like when it stops there.
So: learn the names, because they are the language everyone else is speaking. Use them to describe. Be extremely suspicious of anyone who uses them to forecast, and especially suspicious of a cheat sheet that lists forty patterns and a success rate for each one without telling you where the numbers came from. Now you know roughly what those numbers look like when somebody checks.
What is a doji candle?
A doji is a candle whose open and close land at almost the same price, leaving a tiny body with wicks on both sides. It describes a session where buyers and sellers finished level. There are around nine named doji variants, and their performance records differ enormously, so the label on its own says little about what comes next.
What does a doji mean in trading?
It means indecision — the session went up, went down, and closed roughly where it opened. After a long run in one direction that can be an early hint the move is tiring. On its own, in the middle of a range, it usually means nothing at all. Context decides.
Do candlestick patterns actually work?
They identify reversals more often than a coin flip by most practitioner measurements, but academic tests have generally failed to find a tradeable edge. Studies of Dow stocks (1992–2002), Tokyo's largest 100 stocks (1975–2004) and Thailand's SET50 (2006–2016) all found no reliable excess return. One 2012 study of Taiwanese stocks did find three bullish two-day patterns profitable, so the picture is not unanimous.
What is a bullish engulfing pattern?
Two candles: a down candle, followed by an up candle whose body completely swallows it — opening below the previous close and closing above the previous open. It is read as buyers taking back everything the sellers won. It turns price upward about 63% of the time, but ranks 84th of 103 patterns for the size of the move that follows.
What is the difference between a hammer and a shooting star?
They are the same shape upside down. A hammer has a small body at the top of its range with a long lower wick, and is read as a rejected low. A shooting star has a small body at the bottom with a long upper wick, and is read as a rejected high. Both reverse price around 59–60% of the time, which their own cataloguer describes as close to random.
Which candlestick pattern is the most reliable?
By Bulkowski's overall performance ranking, the morning star is the strongest of the well-known patterns at 12th of 103, well ahead of the far more famous hammer (65th) and bullish engulfing (84th). Reliability here means the size and consistency of the move afterwards, not simply how often the direction changes.
What is the difference between candlestick patterns and chart patterns?
Candlestick patterns are tiny — one to three candles, read over a few sessions. Chart patterns like head and shoulders, triangles and flags are built from many candles over weeks or months, and are described by the structure of their highs and lows rather than the shape of individual bars. They are different tools working on different timescales.
How many candlestick patterns are there?
There is no fixed number, because new names get coined and old ones get subdivided. Bulkowski's catalogue ranks 103 of them. In practice around seven shapes — doji, hammer, shooting star, marubozu, engulfing, morning star and three white soldiers — cover the overwhelming majority of what traders actually reference.
