Price Oscillator

Overview
The Price Oscillator shows a spread of two moving averages.

Interpretation
The Price Oscillator is basically a moving average spread. Buying usually occurs when the oscillator rises, and conversely, selling usually occurs when the oscillator falls.

Note
LongCycle is an integer specifying the number of periods to use in the long moving average calculation, ShortCycle is an integer specifying the number of periods to use in the short moving average calculation, and 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


Syntax

Public function PriceOscillator(ByRef Data As DatabaseByRef Source As Field, ByVal LongCycle As Integer, ByVal ShortCycle As Integer, ByVal MAType As IntegerOptional ByVal FieldAliasName As String = "") As RecordSet

 

Return Type Returns object of type Recordset
Default Field Name(s) PriceOscillator
