Definition
A candlestick summarizes an instrument’s opening, high, low, and closing prices for one selected interval using a body and wicks.
In market context
The body shows the distance between open and close, while the wicks extend to the interval’s high and low. Colors commonly distinguish an interval that closed above its open from one that closed below, although chart conventions can vary. A candle condenses historical price behavior; a pattern built from candles remains interpretive and does not establish what the next interval will do.
