Syntax

Public Function VolumeOscillator(ByRef Data As Database, ByRef Volume As Field, ByVal ShortTerm As Integer, ByVal LongTerm As Integer, ByVal MAType As Integer, ByVal PointsOrPercent As Integer, Optional ByVal FieldAliasName As String = "") As RecordSet

Overview

The Volume Oscillator shows a spread of two different moving averages of volume over a specified period of time.

Interpretation

The Volume Oscillator offers a clear view of whether or not volume is increasing or decreasing.

Note

ShortTerm and LongTerm are both integers specifying the length of time used in the moving average calculations. MAType is an integer specifying the moving average type to be used (Simple = 1, Exponential = 2, TimeSeries = 3, Variable = 4, Triangular = 5, Weighted = 6, VIDYA = 7).
PointsOrPercent is an integer specifying Points output for 1 or Percent output for 2.

Class: Oscillator
