Candle series is similar to Hilo Open Close series. It is used to represent the Low, High, Open and Closing prices over time. To render a candle series, set series Type as Candle.

Hollow Candle

Candle series allows to visually compare the current price with previous price by customizing its 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. BullFillColor property is used to apply when the current closing value is greater than the previous closing value and BearFillColor will be applied when the current closing value is less than the previous closing value. By default, BullFillColor is green and BearFillColor is red.
