The Accumulation Distribution indicator was created by Marc Chaikin and is similar to the On Balance Volume indicator. The main difference between these two indicators is that in the Accumulation Distribution indicator the markets closing price relative to the range is multipled by the volume. Marc Chaikin used this indictor in his Chaikin Oscillator indicator, which calculates the momentum of the accumulation distribution line by using the MACD formula. The one down side to this indictor is that it does not seem to be as strong as on balance volume.
