A candlestick chart is a popular financial charting tool used to visualize price movements of an asset over time, showcasing open, high, low, and close prices for a specific time period. Each candlestick represents a set time interval (e.g., minutes, hours, days) and is composed of a body (the range between the opening and closing prices) and wicks or shadows (representing the highest and lowest prices during that period). The color of the body typically indicates price movement: a filled or colored body signifies a closing price lower than the opening price (bearish), while an unfilled or lighter body represents a closing price higher than the opening price (bullish). Candlestick patterns can signal potential market reversals or continuations, making them useful for traders in technical analysis.
