ta.sar()

Overview

Parabolic SAR (parabolic stop and reverse) is a method devised by J. Welles Wilder, Jr., to find potential reversals in the market price direction of traded goods.

Syntax

ta.sar(start, inc, max) → series float

Parameters

Name	Type	Description
start	simple int/float	Start.

Returns

Parabolic SAR.
