willpctr

Syntax

wpctr = willpctr(highp,lowp,closep,nperiods)
wpctr = willpctr([highp, lowp, closep],nperiods)
wpctrts = willpctr(tsobj)
wpctrts = willpctr(tsobj,nperiods)
wpctrts = willpctr(tsobj,nperiods,'ParameterName',ParameterValue,... )

Arguments

highp

High price (vector)

lowp

Low price (vector)

closep

Closing price (vector)

nperiods

Number of periods (scalar). Default = 14.

tsobj

Financial time series object

Description

wpctr = willpctr(highp,lowp,closep,nperiods) calculates the Williams %R values for the given set of stock prices for a specified number of periods nperiods. The stock prices needed are the high (highp), low (lowp), and closing (closep) prices. wpctr is a vector that represents the Williams %R values from the stock data.

wpctr = willpctr([highp, lowp, closep],nperiods) accepts the price input as a three-column matrix representing the high, low, and closing prices, in that order.

wpctrts = willpctr(tsobj) calculates the Williams %R values for the financial time series object tsobj. The object must contain at least three data series named High (high prices), Low (low prices), and Close (closing prices). wpctrts is a financial time series object with the same dates as tsobj and a single data series named WillPctR.

wpctrts = willpctr(tsobj,nperiods) calculates the Williams %R values for the financial time series object tsobj for nperiods periods.

wpctrts = willpctr(tsobj,nperiods,'ParameterName',ParameterValue, ...) accepts parameter name/parameter value pairs as input. These pairs specify the name(s) for the required data series if it is different from the expected default name(s). Valid parameter names are

  • HighName: high prices series name

  • LowName: low prices series name

  • CloseName: closing prices series name

Parameter values are the character vectors that represent the valid parameter names.

This example shows how to compute the Williams %R values for Disney stock and plot the results.

load disney.mat
dis_Wpctr = willpctr(dis);
plot(dis_Wpctr)
legend('off');
title('Williams %R for Disney')
