VHF: Vertical Horizontal Filter

Description Usage Arguments Details Value Note Author(s) References See Also Examples

Description

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

Usage

1
  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.

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.

Value

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

Note

If Close prices are given, the function calculates the max/min using only those prices (the default). If HLC prices are given, the function calculates the max/min using the high/low prices (added for flexibility).
