Candles
Candlestick
A candlestick is a single bar that shows open, high, low, and close for a time period so you can read price movement at a glance.
A candlestick is the basic building block of modern price charts. Each candle compresses four pieces of information for one chosen time period—open, high, low, and close—into a visual shape that is faster to scan than a table of numbers. The rectangular body shows the distance between open and close. The thin lines above and below, often called wicks or shadows, show how far price traveled beyond that body during the same period. When the close is above the open, many platforms color the body green or hollow; when the close is below the open, they color it red or filled. The coloring is a convention, not a rule of nature, and you should always confirm which scheme your chart uses.
Timeframe matters as much as the candle itself. A five-minute candle and a daily candle use the same OHLC structure, but they describe very different stories. A single loud daily candle can represent hundreds of noisy intraday candles. Beginners often overreact to tiny timeframe candles that reverse within minutes. ChartsQuest emphasizes reading candles in context: location relative to support and resistance, the surrounding trend, and whether volume or participation looks unusual. An isolated candle rarely proves a lasting turn.
Candlesticks became popular in Western markets after traders studied Japanese charting traditions, but their educational value does not depend on history. They help you compare conviction (large bodies) with indecision (small bodies and long wicks). A long upper wick after a rally can mean buyers pushed price up and sellers pushed it back. A long lower wick after a selloff can mean sellers drove price down and buyers absorbed the move. Neither outcome guarantees what happens next. Candles describe what already happened; they do not forecast with certainty.
Risk framing is essential. Treating every colorful candle as a signal invites overtrading. Many candles are ordinary noise. Before you treat a shape as meaningful, ask what would invalidate the idea, where a logical stop would sit relative to the candle's extreme, and whether the lesson on the chart is about recognition rather than prediction. Educational chart reading starts with accurate observation: identify OHLC, note body and wick proportions, and place the candle inside the larger structure of swing highs, swing lows, and ranges.
Example
On a daily chart of a major index, a green candle opens near yesterday's close, trades higher for most of the session, and closes near the high with a short upper wick. The body is tall relative to the prior five days, showing buyers controlled the session from open to close. That does not mean the next day must continue higher; it only documents that day's auction. If the following session gaps down and closes below this candle's midpoint, the prior bullish appearance is already under challenge.
What it is not
A candlestick is not a prediction engine, a buy/sell instruction, or proof that a pattern will complete. It is a compact record of one period's open, high, low, and close.
Frequently asked questions
What do the body and wicks of a candlestick show?
The body shows the distance between open and close. The upper wick shows how far price traded above the body; the lower wick shows how far it traded below. Together they summarize the period's auction.
Does a green candle mean price will keep rising?
No. Color only compares close to open for that period. A green candle can appear in a downtrend, inside a range, or right before a reversal. Context and invalidation matter more than color.
Why do timeframe choices change how candles look?
Shorter timeframes create more candles and more noise; longer timeframes merge many small moves into fewer, broader candles. The same market can look calm on a weekly chart and chaotic on a one-minute chart.
Are candlesticks better than line charts for learning?
Candlesticks show more information per bar than a close-only line. Line charts can still help you see big-picture trend. Many learners use both: candles for structure detail and a smoothed view for orientation.
Termes associés
OHLC
OHLC stands for open, high, low, and close—the four prices that summarize how a market traded during a chosen time period.
Doji
A doji is a candle whose open and close are nearly equal, producing a tiny body that often signals indecision rather than a clear directional win for buyers or sellers.
Hammer
A hammer is a candle with a small body near the top of its range and a long lower wick, often watched after a decline as a possible sign that sellers were rejected.
