Syntax

Public function TRIX(ByRef Data As Database, ByRef Source As Field, ByVal Periods As Integer, Optional ByVal FieldAliasName As String = "") As RecordSet

Overview

TRIX is a momentum oscillator that shows the rate of change of an exponentially averaged closing price.

Interpretation

The most common interpretation of the TRIX oscillator is to buy when the oscillator rises and sell when the oscillator falls. 3, 8 and 14-period moving averages are often used to smooth the TRIX oscillator.

Class: Oscillator
