Usage

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.
