Syntax

Public function ChaikinVolatility(ByRef Data As Database, ByRef OHLCV As RecordSet, ByVal Periods As Integer, ByVal ROC As Integer, ByVal MAType As Integer, Optional ByVal FieldAliasName As String = "") As RecordSet

Overview

The Chaikin Volatility Oscillator is a moving average derivative of the Accumulation/Distribution index.

Interpretation

The Chaikin Volatility Oscillator adjusts with respect to volatility, independent of long-term price action.

Note

ROC is an integer specifying the Rate Of Change to use in the Chaikin 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).

Class: Oscillator
