Hollow Candles

Candle charts allow to visually compare the current price with previous price by customizing the appearance.

Candles are filled/left as hollow based on the following criteria.

States Description
Filled candle sticks are filled when the close value is lesser than the open value
Unfilled candle sticks are unfilled when the close value is greater than the open value

The color of the candle will be defined by comparing with previous values.

Bear color will be applied when the current closing value is greater than the previous closing value. Bull color will be applied when the current closing value is less than the previous closing value.

By default, bullFillColor is set as red and bearFillColor is set as green.

Solid Candles

enableSolidCandles is used to enable/disable the solid candles. By default is set to be false. The fill color of the candle will be defined by its opening and closing values.

bearFillColor will be applied when the opening value is less than the closing value. bullFillColor will be applied when the opening value is greater than closing value.
