Candlestick

The candlestick is the fundamental visual unit across most modern technical analysis platforms. It originated in Japan centuries ago to track rice prices before gaining worldwide adoption in financial markets. A candlestick consists of two primary components: the body, which represents the range between the opening and closing prices, and the wick or shadow, which marks the highest and lowest prices traded during that period.

If the price closes above the open, the candlestick is bullish and typically colored green or white; if it closes below the open, it is bearish and usually colored red or black. The length of the body reflects the strength of the directional move, while the length of the wicks reflects price volatility and rejection at certain levels.

Candlesticks serve as the building blocks for candlestick patterns—such as the hammer, shooting star, and engulfing patterns—which help traders interpret market psychology and anticipate trend continuations or reversals. Candlesticks can be plotted across any timeframe, from a single minute to an entire month, providing extensive analytical flexibility.

A common mistake is interpreting a single candlestick in isolation from the broader market context, or ignoring the accompanying trading volume. It is best practice to evaluate a candlestick within a series of consecutive candles and align it with key support and resistance levels to achieve a more precise and reliable read.
