Volume Oscillator Formula (Chart Controls)

  • Artigo

The volume oscillator formula measures the difference between a short period moving average of volume and a long period moving average of volume. A positive value indicates a strong trend, and a negative value indicates a weak trend.

Formula Details

Syntax

Chart.DataManipulator.FinancialFormula(
    FinancialFormula.VolumeOscillator,
    "PeriodShort,PeriodLong,UsePercentage",
    "Volume",
    "VO")

Parameters

This formula takes three optional parameters.

  • PeriodShort
    Period for calculating the short period moving average. The default value is 5.
  • PeriodLong
    Period for calculating the long period moving average. The default value is 10.
  • UsePercentage
    Whether to output the difference in percentage. When set to false, the formula outputs the difference as a point. The default value is true.

Input Values

This formula takes one input Y value.

  • Volume
    Volume for which the volume oscillator indicator is calculated.

Output Value

This formula outputs one Y value.

  • VO
    Volume oscillator indicator.

Remarks

The Line chart type is a convenient chart type to display the formula output.

Example

The following example takes input from Series1's Y value for volume (Series1:Y) and outputs the volume oscillator indicator on Series2 (Series2:Y). It uses a short period of 10 days and a long period of 30 days.

Chart1.DataManipulator.FinancialFormula (FinancialFormula.VolumeOscillator, "10,30,true", "Series1:Y", "Series3:Y")

Chart1.DataManipulator.FinancialFormula (FinancialFormula.VolumeOscillator, "10,30,true", "Series1:Y", "Series3:Y");
