NegativeVolumeIndex

Summary

Dysart's Negative Volume Index assumes that the smart money is active on days when volume decreases and the not-so-smart money is active on days when volume increases (measured by the Positive Volume Index).

Syntax

public interface NegativeVolumeIndex

Members

Name	Type	Summary
Result	Property	The time series of the Negative Volume Index indicator.

Example 1

private NegativeVolumeIndex _negativeVolume;
[Parameter]
public DataSeries Source { get; set; }
[Output("Main")]
public IndicatorDataSeries Result { get; set; }
protected override void Initialize()
{
   _negativeVolume = Indicators.NegativeVolumeIndex(Source);
}
public override void Calculate(int index)
{
   // Display Result of Indicator
   Result[index] = _negativeVolume.Result[index];
}
