Stochastic Wijmo API Class

Stochastic Class

Represents a Stochastic Oscillator indicator series for the FinancialChart.

Stochastic oscillators are momentum indicators designed to predict price turning points by comparing an asset's closing price to its high-low range.

The Stochastic series can be used for fast (default), slow and full stochastic oscillators. To create a slow or full stochastic oscillator, set the smoothingPeriod to an integer value greater than one; slow stochastic oscillators generally use a fixed smoothingPeriod of three. To create or revert to a fast stochastic oscillator, set the smoothingPeriod to an integer value of one.

Properties

altStyle

altStyle: any

Gets or sets the alternate style for the series.

The alternate style is used for negative values in Bar, Column, and Scatter charts; and for rising values in financial chart types like Candlestick, LineBreak, EquiVolume etc.

The default value for this property is null, which causes the series to use the default style.

axisX

axisX: Axis

Gets or sets the X-axis for the series.

axisY

axisY: Axis

Gets or sets the Y-axis for the series.

binding

binding: string

Gets or sets the name of the property that contains Y values for the series.

bindingX

bindingX: string

Gets or sets the name of the property that contains X values for the series.

chart

Gets the FlexChart object that owns this series.

collectionView

collectionView: ICollectionView

Gets the ICollectionView object that contains the data for this series.

cssClass

cssClass: string

Gets or sets the series CSS class.

dPeriod

dPeriod: number

Gets or sets the period for the %D simple moving average.

hostElement

hostElement: SVGGElement

Gets the series host element.

interpolateNulls

interpolateNulls: boolean

Gets or sets a value that determines whether to interpolate null values in the data.

If true, the series interpolates the value of any missing data based on neighboring points. If false, it leaves a break in lines and areas at the points with null values.

The default value for this property is false.

itemFormatter

itemFormatter: Function

Gets or sets the item formatter function that allows you to customize the appearance of the series.

The property overrides the chart's itemFormatter wijmo.chart.FlexChart.itemFormatter.

itemsSource: any

Gets or sets the array or ICollectionView object that contains the series data.

kPeriod

kPeriod: number

Gets or sets the period for the %K calculation.

legendElement

legendElement: SVGGElement

Gets the series element in the legend.

name

name: string

Gets or sets the series name.

The series name is displayed in the chart legend. Any series without a name does not appear in the legend.

smoothingPeriod

smoothingPeriod: number

Gets or sets the smoothing period for full %K.

style

style: any

Gets or sets the series style.

styles

styles: any

Gets or sets the styles for the %K and %D lines.

The following options are supported:

series.styles = {
  kLine: {
     stroke: 'red',

  },
  dLine: {
     stroke: 'green',
     strokeWidth: 1
  },
}

symbolMarker

symbolMarker: Marker
