## Williams Accumulation / Distribution

### Description

The Williams Accumulation / Distribution (AD) line is a measure of market momentum. Developed by Larry Williams.

### Usage

    williamsAD(HLC)

### Arguments

`HLC` | Object that is coercible to xts or matrix and contains High-Low-Close prices.

### Details

The Williams AD line differs from OBV and chaikinAD in that it doesn't take volume into account.

### Value

A object of the same class as `HLC` 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.
