WPR: William's %R

Description

William's % R.

Usage

WPR(HLC, n = 14)

Arguments

HLC

Object that is coercible to xts or matrix and contains High-Low-Close prices. If only a univariate series is given, it will be used. See details.

n

Number of periods to use.

Value

A object of the same class as HLC or a vector (if try.xts fails) containing the William's %R values.

Details

If an High-Low-Close series is provided, the indicator is calculated using the high/low values. If a vector is provided, the calculation only uses that series.
