The candlestick patterns that matter and how to read them

Every candle on a chart is the record of one fight between buyers and sellers — who opened the session, how far they pushed price, and who had the last word at the close. A single candle rarely tells the whole story, yet a handful of specific shapes keep repeating across markets, because they describe the same human reflexes again and again: greed, fear and hesitation. Below I gather the patterns worth recognising first, and show how to read them without slipping into wishful thinking.

What the shape of a candle actually tells you

Before the names, we need a shared language. Every candle carries four numbers: the open, the high, the low and the close. The body is the distance between open and close, while the shadows (wicks) are the thin lines reaching to the extremes of the session. A bullish candle closes above its open, a bearish one below. That is the whole mechanism — everything else is interpretation.

The most important rule is simple: a long body means conviction, a long shadow means rejection. A strong green body with no upper shadow says buyers controlled the session from start to finish. A long lower shadow on a small body says something else entirely — price fell deep, but someone pushed it back up before the close. Once you learn to read that relationship between body and wicks, most patterns become obvious. If you want to settle the basics first, start with the piece on which candlestick patterns are worth knowing first.

Rejection candles: when one side runs out of strength

The first group is made of single candles that signal the current move has hit a wall. The hammer appears after a fall: it has a small body near the top and a long lower shadow, usually two to three times the length of the body. It tells the story of a session in which sellers drove price low, only for buyers to lift it back before the close. Its mirror at the top is the shooting star — the same shape turned upside down, with a long upper shadow that betrays the exhaustion of buyers. I unpack the logic and the traps of the hammer separately in the piece on the hammer pattern.

The doji belongs to the same family — a candle whose open and close land in almost the same place, so the body is as thin as a line. The doji predicts no direction; it only says both sides fought to a draw and that the prevailing confidence has weakened. After a long trend, that draw is often the first hint that something is changing. Its close cousin, the spinning top, with a small body and shadows on both sides, carries a similar message of indecision — I cover both at length in the piece on the doji and market indecision.

Takeover patterns: when the other side steps in hard

The second group is made of two- and three-candle formations in which the initiative clearly changes hands. The clearest is the engulfing pattern: the second candle has a body so large that it completely engulfs the body of the one before. A bullish engulfing after a fall — a green body swallowing the earlier red one — says buyers erased the whole of the previous session in a single move. A bearish engulfing at the top carries the opposite message. According to Thomas Bulkowski's data, the bullish engulfing acts as a bullish reversal 63 percent of the time, which makes it a solid if not infallible signal. I work through the full pattern in the piece on the bullish and bearish engulfing.

The stars are more elaborate. The morning star is made of three candles: a strong bearish one, then a small candle or doji that signals hesitation, and finally a strong bullish one that completes the turn upward. The evening star is its exact reflection at the top. The three white soldiers, in turn, are three consecutive strong bullish candles forming an even staircase — a calm, consistent return of demand. On the selling side they are answered by the three black crows. These multi-candle formations tend to be more reliable than single signals precisely because they tell a story spread across several sessions; I develop them in the pieces on the morning star and the three white soldiers.

Hesitation patterns: harami and half retracements

The third group does not shout reversal — it whispers loss of momentum. The harami is the opposite of the engulfing: after a large candle comes a small one that fits entirely inside the previous body. It signals that the current move suddenly lost its energy and the market caught its breath — often a prelude to consolidation or a turn, though only the next candle settles the direction. I describe this formation, together with its bullish and bearish versions, in the piece on the harami pattern.

The same category holds the half-retracement formations: the piercing pattern on the buyers' side and the dark cloud cover on the sellers' side. In both, the second candle pushes roughly halfway into the previous body — a weaker signal than a full engulfing, because the takeover of initiative is only partial. They are worth knowing, but treat them as a hint that needs confirmation rather than a standalone reason to enter.

"The shape of a single candle is like a snapshot of market sentiment — it shows who really controlled the session when the close came in." — Steve Nison, Japanese Candlestick Charting Techniques, New York Institute of Finance, 2001.

Why no candle is a signal on its own

This is the most important paragraph in the whole text. Statistics like "63 percent" or "78 percent" come from studies of millions of candles and describe how a pattern performs under ideal conditions — not a guarantee for any single trade. The same engulfing pattern in the middle of a chaotic consolidation means something completely different from the same shape at a major resistance level on the daily chart. Candles do not work in a vacuum; they work in context.

That is why experienced readers do not ask "which pattern is this", but "where did this pattern appear". A rejection candle right at a level of support or resistance, aligned with the trend on the higher timeframe and confirmed by the next session, weighs many times more than the same candle in a random spot. The more independent reasons converge on one point, the stronger the signal — and the less guessing involved. I explain how to mark those levels in the piece on how to draw support and resistance.

Let us walk through a hypothetical, purely illustrative example. Imagine that on EUR/USD price has been falling for several days and reaches a clear support level that already held twice before. A hammer appears there with a long lower shadow, and the next candle is strongly bullish and closes above the hammer's body. You then have three aligned reasons: rejection of the level, a known support level, and confirmation from the next candle. That is a completely different situation from a lone hammer hanging in the middle of a downtrend with nothing to lean on. The numbers and levels here are illustrative — they show the way of thinking, not a recommendation.

What to do tomorrow

1. Train your eye on historical charts. Open any currency pair on the daily timeframe, scroll back a few months and find one example each of a hammer, an engulfing and a morning star — then check what happened next, so you can see when the pattern worked and when it failed.
2. Learn to separate the body from the shadow. For each candle you find, say out loud whether it speaks of conviction (a long body) or rejection (a long shadow), because that distinction is the foundation of reading every formation and protects you from mistaking a weak signal for a strong one.
3. Write down your own context rule. Commit it to paper that you react to no single candle until it appears at a meaningful support or resistance level, in line with the higher-timeframe trend and confirmed by the next session — one rule that removes most rushed entries.
4. Practise everything on a demo account for a week. Catch formations live, note for each one where it appeared and which other reasons support it, and record the results in a journal — only repeatability on demo earns you the right to trade the same setups with real money.
