All 26 of the common patterns, drawn from their actual open, high, low and close values rather than from memory. Each one says what the shape is, and what the session behind it did.
What a candle actually records
Every candle is four numbers from one period: the price it opened at, the highest and lowest it traded, and the price it closed at. The body spans open to close, and the wicks reach out to the extremes. That is the whole encoding — a candle carries no information about what happened in what order inside the period, which is why a hammer and a session that fell steadily and rebounded in the last minute look identical.
Patterns are just named combinations of those four numbers across one to five periods. The names are Japanese in origin, from rice traders in the eighteenth century, and were brought into English-language technical analysis largely through Steve Nison's work in the 1990s. Nothing about the naming makes any of them predictive; it makes them a shared vocabulary for shapes people were already looking at.
Context is what names the pattern
Four of the patterns on this page are the same drawing as another one. Hammer and hanging man are identical; so are inverted hammer and shooting star. What separates each pair is the move it interrupts — the shape is evidence about one session, and the trend around it is what gives that evidence a direction.
This is also why a cheat sheet, this one included, can only take you so far. Matching a shape is the easy half. The judgement is in whether the level it formed at has mattered before, whether the volume behind it was unusual, and whether the move it is supposedly reversing was long enough for a reversal to be a meaningful idea.
How much weight the shapes carry
Less than most introductions suggest. Published tests of candlestick patterns have produced mixed and often weak results, and they are sensitive to how the pattern is defined — how small a body counts as "small", how long a wick has to be, whether a near-gap counts as a gap. Change those thresholds and the same dataset gives a different answer, which is a strong hint that the effect being measured is not large.
The defensible use is descriptive. A long lower wick genuinely does record that price traded much lower during the period and did not stay there. That fact is worth having, whether or not the pattern it belongs to has a name, and it stays true regardless of what the next period does.
Reading the groups
The four groups on this page describe what a shape records, not what it forecasts. Reversal patterns are sessions where a prevailing move met resistance from the other side. Indecision patterns are sessions that finished where they started. Continuation patterns are pauses that stayed inside the range of the move they interrupted. A pattern landing in the "bullish" group is a statement about which side won that session, and nothing more than that.
