DVI: DV Intermediate Oscillator

Description

The DV Intermediate oscillator (DVI) is a very smooth momentum oscillator that can also be used as a trend indicator. Created by David Varadi.

Usage

DVI(price, n=252, wts=c(0.8,0.2), smooth=3,
      magnitude=c(5,100,5), stretch=c(10,100,2))

Arguments

price

Price series that is coercible to xts or matrix.

n

Number of periods for the percent rank.

wts

The weight given to the smoothed returns (magnitude) component and the up/down days (stretch) component, respectively.

smooth

The number of periods to smooth price.

magnitude

A set of 3 periods used to smooth magnitude.

stretch

A set of 3 periods used to smooth stretch.

Value

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

Details

The DVI combines smoothed returns over different time windows and the relative number of up versus down days (stretch) over different time windows.
