PFE (Function)

$image\trumpet2.gif$ Disclaimer

The PFE (Polarized Fractal Efficiency) function calculates an efficiency of price movement between two price points by comparing the straight-line distance between the two price points to the actual distance that price traveled between the two price points. The calculations are based on the Pythagorean theorem. See referenced article below for more information.

Syntax

PFE(Price, Length, UseAdjustedBaseLength)

Returns (Double)

A numeric value for the fractal efficiency of the price movement between the two price points Length bars apart.

points

Parameters

Name	Type	Description
Price	NumericSeries	Set the price to use in calculations.
Length	Numeric	Sets the number of bars over which the efficiency is calculated.
UseAdjustedBaseLength	TrueFalse	True when the number of bars over which the price change occurred is the value of the Length input minus one; False when the number of bars over which the price change occurred is the value of the Length input
