willad

Williams Accumulation/Distribution line

Syntax

wadl = willad(highp, lowp, closep)
wadl = willad([highp lowp closep])
wadlts = willad(tsobj)
wadlts = willad(tsobj, ParameterName, ParameterValue, ...)

Arguments

highp

High price (vector)

lowp

Low price (vector)

closep

Closing price (vector)

tsobj

Time series object

Description

wadl = willad(highp, lowp, closep) computes the Williams Accumulation/Distribution line for a set of stock price data. The prices needed for this function are the high (highp), low (lowp), and closing (closep) prices. All three are required.

wadl = willad([highp lowp closep]) accepts a three-column matrix of prices as input. The first column contains the high prices, the second contains the low prices, and the third contains the closing prices.

wadlts = willad(tsobj) computes the Williams Accumulation/Distribution line for a set of stock price data contained in the financial time series object tsobj. The object must contain the high, low, and closing prices needed for this function. The function assumes that the series are named High, Low, and Close. All three are required. wadlts is a financial time series object with the same dates as tsobj and a single data series named WillAD.

wadlts = willad(tsobj, 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 strings that represent the valid parameter names.
