R: Chaikin Accumulation / Distribution

chaikinAD {TTR} | R Documentation

## Chaikin Accumulation / Distribution

### Description

The Chaikin Accumulation / Distribution (AD) line is a measure of the money flowing into or out of a security. It is similar to On Balance Volume (OBV). Developed by Marc Chaikin.

### Usage

    chaikinAD(HLC, volume)

### Arguments

`HLC` | Object that is coercible to xts or matrix and contains High-Low-Close prices.
`volume` | Vector or matrix of volume observations corresponding to the `HLC` object.

### Details

The AD line is similar to OBV; the difference is that OBV sums volume multiplied by +/- 1 if the close is higher/lower than the previous close, while the AD line multiplies volume by the close location value (CLV).

### Value

A object of the same class as `HLC` and `volume` or a vector (if `try.xts` fails) containing the accumulation / distribution values.

### Note

The Accumulation/Distribution Line is interpreted by looking for a divergence in the direction of the indicator relative to price.
