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.
chaikinAD(HLC, volume)A object of the same class as HLC and volume or a
vector (if try.xts fails) containing the accumulation / distribution
values.
Object that is coercible to xts or matrix and contains High-Low-Close prices.
Vector or matrix of volume observations corresponding to the
HLC object.
Joshua Ulrich
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).
