How to Read Candlestick Charts: What Each Part Actually Means

Candlesticks record what buyers and sellers did during a period. Reading them is reading the balance of pressure.

A candlestick represents four prices: the open, the high, the low, and the close during a chosen period. That one candle summarises everything that happened between buyers and sellers in that time.

The anatomy of a candle

Body: the rectangle between the open and close. A green (or white) body means price closed higher than it opened. A red (or black) body means price closed lower.

Upper wick (shadow): the thin line above the body. It shows how high price moved before being pushed back down.

Lower wick: the thin line below the body. It shows how low price moved before being pushed back up.

The length of each part carries information.

What a long upper wick means

Price moved significantly higher during the period but sellers pushed it back down before close. The higher the close relative to the total range, the stronger the buyers still were at the end. The lower the close, the more completely sellers rejected the move.

A long upper wick near a resistance level, where the candle closes back near its lows, is often read as rejection — sellers were strong enough to push price all the way back.

What a long lower wick means

The opposite: buyers stepped in strongly after a move down. The further price closed above the low, the more decisively buyers responded.

A long lower wick at a support level is often read as a demand response — buyers absorbed the selling and pushed back.

Common single-candle patterns

Doji: open and close are almost identical. The candle is mostly wick. It signals indecision — neither side dominated the period.

Hammer: small body at the top of a long lower wick. Buyers rejected a sharp move down. Watched for at the bottom of downtrends.

Shooting star: small body at the bottom of a long upper wick. Sellers rejected a sharp move up. Watched for at the top of uptrends.

Marubozu: full body candle with no wicks, or minimal ones. One side dominated completely for the entire period. In a strong trend, these confirm momentum.

Common two and three-candle patterns

Engulfing: a candle whose body completely covers the previous candle's body. A bullish engulfing at a support zone often signals a reversal attempt. A bearish engulfing at resistance often signals the same in the other direction. Reliability increases when the engulfed candle is small and the engulfing candle is large.

Morning star: three candles — a large bearish candle, a small indecision candle (often a doji), then a large bullish candle. Signals a potential reversal from a downtrend.

Evening star: the reverse — bullish, indecision, bearish — at the top of an uptrend.

What candlesticks do not tell you

Candlestick patterns are not predictions. They describe what has happened, and some configurations appear more often before certain moves than others. But the same hammer candle at a support zone produces a reversal sometimes and a continued decline other times.

The pattern provides a location and a context. It needs a reason to act on — the level at which it appears, the overall trend, and whether the setup matches the conditions your method requires.

A chart full of labelled candle patterns without context is a collection of names, not a trading system.

Using candlesticks practically

Focus on the wick location relative to the body, not the pattern name. A candle that closes in the upper third of its range is a different message from one that closes in the lower third, regardless of whether it technically qualifies as any named pattern.

At support: do buyers push back strongly (long lower wick, high close)?

At resistance: do sellers push back strongly (long upper wick, low close)?

Those two questions answer most of what candlestick analysis is trying to ask.
