When the ChartType property is set to Candle, you can use the following properties to indicate a rising or falling stock price:

• FillFalling
• FillTransparent

To show falling prices

Set the FillFalling property to True. The color of the fill is determined by the value of the ChartDataSeries.LineStyle.

To show raising prices

Set the FillTransparent property to True. This will make the body of the open candles transparent or hollow. If you would like to specify a color for the raising values, then set the FillTransparent property to False and specify a color for the SymbolStyle property. Note that is is recommended to use a different color so there is one color for the line style and a different color for the symbol style.
