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.
