Syntax

Public function PrabolicSAR(ByVal Data As Database, ByVal HighPrice As Field, ByVal LowPrice As Field, Optional MinAF As Double, Optional MaxAF As Double, Optional FieldName As String) As RecordSet

Overview

The Parabolic SAR is always in the market (whenever a position is closed, an opposing position is taken).

Interpretation

The Parabolic SAR indicator is most often used to set trailing price stops. A stop and reversal (SAR) occur when the price penetrates a Parabolic SAR level.

Class: Oscillator
