Candlestick
A candlestick is a price bar showing the open, high, low, and close for a period, used to read momentum at a glance.
Also known as: candle, candlestick chart
Anatomy of a candlestick
A candlestick represents all the price action within a single period — a day, an hour, a minute. The thick 'body' spans the open and close; the thin 'wicks' (or shadows) above and below mark the high and low. A close above the open is usually drawn green (bullish); a close below it red (bearish).
Candlesticks are the default way crypto charts are drawn because their shape encodes momentum: long bodies show conviction, long wicks show rejection of a price level, and recurring patterns of candles form the basis of much of technical analysis.
