The candlestick chart is a style of financial chart describing open, high, low, and close for a given x coordinate (most likely time).
- The boxes represent the spread between the open and close values and the lines represent the spread between the low and high values.
- Sample points where the close value is higher (lower) than the open value are called increasing (decreasing).
- By default, increasing candles are drawn in green whereas decreasing are drawn in red.
