TTR (version 0.23-1)

VHF: Vertical Horizontal Filter

Description

The Vertical Horizontal Filter (VHF) attempts to identify starting and ending trends. Developed by Adam White.

Usage

VHF(price, n = 28)

Arguments

price

Object that is coercible to xts or matrix and contains a Close price series, or a High-Low-Close price series.

n

Number of periods to use.

Value

A object of the same class as price or a vector (if try.xts fails) containing the VHF values.

Details

The VHF is calculated by subtracting the n-period lowest low from the n-period highest high and dividing that result by the n-period rolling sum of the close price changes.
