public Color DownCloseColor {get; set;}
Remarks
By default, UpCloseColor is White and DownCloseColor is Red.
Each Candle will be filled with a different color depending on its Open and Close values.
If Open value is greater than Close value, then the selected color will be the UpCloseColor color property.
If Close value is greater or equal than Open value, then the selected color will be the DownCloseColor color property.
Example
You can change both the color values at design or runtime :
[C#]
((Steema.TeeChart.Styles.Calendar)tChart1[5]).UpCloseColor = Color.DarkCyan;
((Steema.TeeChart.Styles.Calendar)tChart1[5]).DownCloseColor = Color.Coral;
That will force to repaint the Chart class containing CandleSeries1.
