A single candlestick already tells you a story — where price opened, where it closed, and how far it traveled in between. How to Read a Price Chart covers that basic anatomy. This lesson goes one level deeper: specific, named shapes that traders watch for because they tend to mark the moment one side of the market — buyers or sellers — loses control. Learn to read a handful of these well, and you'll notice them on almost every chart you open.
Anatomy of a Candlestick, Revisited
Every candlestick encodes four prices for its period: open, high, low, close. The body is the thick rectangle between the open and close — it shows which side won that period. The wicks (or shadows) are the thin lines above and below the body, marking the highest and lowest price reached before the candle closed. Color tells you direction at a glance: a candle that closes above where it opened is bullish (usually green), one that closes below is bearish (usually red).
For pattern-reading specifically, two things matter more than the raw color:
- Body size relative to the wick — a long body means one side was in firm control the whole period; a small body inside long wicks means both sides pushed and neither held.
- Where the body sits inside the candle's full range — a body near the top with a long lower wick means sellers pushed price down and then lost it back to buyers before the close. That single fact is the entire logic behind several of the patterns below.
Doji: The Sign of Indecision
A Doji forms when the open and close are nearly identical, leaving a body so thin it looks like a cross or a plus sign. Price may have swung several pips in both directions during the period, but by the close, neither buyers nor sellers had actually won.
On its own, a Doji doesn't say "reversal" or "continuation" — it says pause. Context decides which of those it turns into. A Doji appearing in the middle of a quiet, choppy range is meaningless; that's what indecision looks like all day in a range. The same Doji appearing after a long, one-directional run — five or six candles pushing hard in the same direction — is far more interesting, because it's the first candle in that run where the dominant side failed to make further progress. That's often the earliest visible sign that a trend is losing momentum, even before any reversal candle confirms it.
Hammer and Shooting Star
A Hammer has a small body sitting near the top of its range, with a lower wick at least twice the length of the body and little or no upper wick. Read as a story: sellers pushed price sharply lower during the period, then buyers stepped in hard enough to drag it almost all the way back to where it opened. That rejection, appearing after a downtrend, is read as a bullish reversal signal — sellers tried to extend the move and were overpowered.
The mirror image, a Shooting Star, has a small body near the bottom of its range with a long upper wick — buyers pushed price up, sellers rejected it, and it closed back near the open. Appearing after an uptrend, it's read as a bearish reversal signal for the same reason in reverse. Both patterns are about the same idea: a long wick is a record of a failed attempt, and the failure is what makes it meaningful.
One detail worth remembering: a Hammer's color is almost secondary to its shape. A hammer with a small red body still counts, because what matters is the rejection recorded by the long wick, not whether the tiny body closed a few pips above or below the open.
Bullish and Bearish Engulfing
Where a Doji and a Hammer are single-candle patterns, Engulfing patterns need two. A Bullish Engulfing pattern is a red candle followed by a green candle whose body fully covers — engulfs — the body of the candle before it: the second candle opens below (or at) the first candle's close and closes above the first candle's open. It shows buying pressure that didn't just stop the decline but reversed it decisively within a single period.
A Bearish Engulfing pattern is the same idea flipped: a green candle followed by a red candle whose body fully swallows it, opening above (or at) the prior close and closing below the prior open. It records sellers taking full control after a period of buying.
Engulfing patterns tend to read as more decisive than a Hammer or Doji precisely because they involve two full periods of trading rather than one — the reversal isn't just a wick, it's an entire candle's worth of momentum reversing direction. That's why many traders treat a clean Engulfing pattern as a stronger signal than a single-candle pattern in the same location.
Context Matters More Than the Candle Itself
None of these patterns work reliably in isolation, and that single point matters more than memorizing their shapes. A Hammer that forms in random space in the middle of a range is just noise — plenty of candles have long lower wicks for no meaningful reason. The same exact Hammer forming right at a support level that has held price up three times before is a genuinely different signal: the pattern is the confirmation, and the level is the reason a reversal is plausible there in the first place.
The same logic applies to trend. A Bearish Engulfing candle after a strong, established uptrend (see Trend vs Range) means there's an actual move to reverse — buyers who had been in control for many candles just lost a whole period to sellers. A Bearish Engulfing candle inside a directionless chop doesn't mean much, because there was no clear trend for it to reverse. As a rule of thumb: the more established the prior move and the closer the pattern sits to a level that's already proven itself, the more weight the pattern deserves. When a candlestick pattern lines up with a larger chart pattern like a Double Top or the neckline of a Head and Shoulders, that agreement across timeframes and pattern types is a stronger signal than either one alone.
Common Mistakes
- Trading every Doji or Hammer that appears. These patterns show up constantly on lower timeframes; most of them occur nowhere near a meaningful level and should simply be ignored, not traded.
- Ignoring the broader trend. A bullish reversal pattern fighting a strong downtrend is a low-probability trade regardless of how textbook it looks — see Trend vs Range for how to judge whether a trend is actually strong enough to respect.
- Acting before the candle closes. A Hammer's long lower wick can vanish in the final minutes of the period if price rallies and then fades again — the pattern is only valid once the candle has actually closed with that shape intact.
- Treating a pattern as a target, not just an entry signal. A candlestick pattern tells you a reversal might be starting; it says nothing about how far the move will go. Pair it with a plan — where the Stop Loss goes if the pattern fails, and where the Take Profit sits — rather than trading the shape alone.
- Skipping higher timeframes. A Hammer on a 1-minute chart reflects a few minutes of order flow and can be produced by a single large order; the same shape on a 4-hour or daily chart reflects far more real trading activity and tends to be considerably more reliable.
Candlestick patterns are a fast, visual way to read who's winning a fight over price — but they're a tool for confirmation, not a stand-alone system. Combine them with the levels and trend context covered in Support and Resistance and Trend vs Range, and once you're comfortable spotting these single- and two-candle shapes, Chart Patterns covers the larger, multi-candle formations that build on the same logic.
