TrueRangeIndicator measures the daily range with addition to any gap from the closing price of the preceding day.

To set up the indicator you can set its CategoryBinding, HighBinding, LowBinding, CloseBinding, and ItemsSource properties.

Example 1: Defining TrueRangeIndicator

    <telerik:TrueRangeIndicator CategoryBinding="Date"  
                                ItemsSource="{Binding Data}"/> 

Figure 1: TrueRangeIndicator

Figure 1 shows 2 instances of RadCartesianChart. The top one shows only the candlestick series that displays the original data. The chart on the bottom shows the indicator.

The indicator can be set up the same way as a normal chart series. This is why you can populate it using the same approach as shown in the Data Bind to Data-Object article. You can set the corresponding value binding properties - for example, ValueBinding, CategoryBinding, HighBinding, CloseBinding, etc, and also the ItemsSource.
