A candlestick is one of the most common ways to look at price. It compresses a lot of information into a small shape, but only if you know what each part represents and how to interpret it with context.
What a candle actually shows
Each candle summarizes open, high, low and close (OHLC) for one interval. The body runs between the open and the close, and the thin lines above and below, the wicks, reach the high and low of that interval.
The colour or fill conventionally distinguishes a close above the open from a close below the open. The meaning is the same either way: the body tells you where price opened and closed relative to each other, and the wicks tell you how far price ranged.
Reading the shape
A long body with short wicks shows price moving decisively in one direction. A short body with long wicks on both sides, sometimes called a doji, shows the close landing near the open, which can signal indecision rather than a confirmed reversal.
A long wick in one direction suggests price was pushed that far and then rejected. A rejection near a level traders are watching can be informative, but the same wick can appear before a continued move in the same direction.
Timeframes change the story
A 15-minute candle and a weekly candle describe very different windows. A pattern that looks strong on a short timeframe may be a small wick on a longer one. Always name the timeframe you are reading before drawing a conclusion.
Using several timeframes is a common approach: a longer view for context and a shorter view for timing. The longer timeframe is generally the one that should carry more weight in the overall read.
Context and limits
Candlesticks describe past price action. They do not forecast the future, and no single pattern is a reliable entry or exit by itself. Volume, the surrounding market structure and your risk plan all matter more than any one shape.
Treat candles as a way to structure observations and to communicate a view, not as a standalone prediction engine.
Frequently asked questions
What do the open, high, low and close of a candle represent?
They are the four prices observed in one interval: the first traded price (open), the highest (high), the lowest (low) and the final traded price (close). The body connects the open and close; the wicks reach the high and low.
Does a specific candlestick pattern guarantee a reversal?
No. Patterns summarize past price action and can describe indecision or rejection, but they are not guarantees. They should be evaluated with volume, surrounding levels and a clear invalidation, and never traded as a standalone signal.
Which timeframe should I look at?
It depends on the context of your decision. A longer timeframe gives more stable structure while a shorter one can help with timing. Using both, with the longer timeframe given more weight, is a common approach.
