When value of A/D goes up it means that financial instrument is accumulated. In case when value of A/D is falling it means that financial instrument is distributed.

Buying and selling signals could be generated using divergence: if price of security is falling, but value of A/D is rising (positive divergence) we could expect that soon prices will start to grow. Similar applies to up trend (when price is rising and A/D is falling, soon trend will change).
