| Type | Description |
|---|---|
| ReductionStockOptions | A ReductionStockOptions object that contains the price reduction indication settings. |
Remarks
The ReductionOptions property provides access to the settings that define how a price reduction is indicated within a series of the stock and candle stick types. The settings which are available via the ReductionOptions property allow you to define a particular price value (open, close, high or low) which the analysis of the price action is performed by, specify a color to indicate the price reduction and control whether price reductions are indicated within a series.
Example
This example demonstrates how to create a ChartControl with a series of the CandleStickSeriesView type, and add this chart to a form at runtime. Before proceeding with this example, create a Windows Forms Application in Visual Studio, and add all required assemblies to the References list of your project.
Then, add the following code to the Form.Load event handler.
Note that you can exclude non-working days (weekends and holidays) from an axis range via the DateTimeScaleOptions.WorkdaysOnly and DateTimeScaleOptions.WorkdaysOptions properties. Refer to Indicators for information on the financial indicators available for XtraCharts.
