What a candlestick shows
Each candlestick represents price activity over one period, such as a minute, hour, or day. The rectangular body spans the opening and closing prices, while the thin lines above and below, called wicks or shadows, mark the highest and lowest prices reached. Together these four values summarize how price moved during that period.
Reading color and shape
By convention, a candle is colored one way when the close is above the open and another way when the close is below it. A long body suggests a wide range between open and close, while long wicks show price reached far from where the period settled. Color schemes vary between platforms.
Patterns and their limits
Traders study sequences of candles, sometimes called patterns, to describe recent behavior such as indecision or strong directional moves. These patterns summarize what already happened and are interpreted differently by different analysts. They do not predict future prices and are best used alongside broader context rather than in isolation.
