BollingerBandsIndicator is used to define the prevailing high and low values in the data.

To set up the indicator you can set its CategoryBinding, ValueBinding and ItemsSource properties. Additionally, you can control the period (in days) over which the indicator will be applied. To do this set the Period property.

To set the number of standard deviations used to calculate the indicator values you can use the StandardDeviations property. And the stroke of the lower band is set via LowerBandStroke property.

Example 1: Defining BollingerBandsIndicator

      <telerik:BollingerBandsIndicator Period="5"  
                                       ItemsSource="{Binding Data}"/> 

Figure 1: BollingerBandsIndicator

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.
