Williams Accumulation / Distribution is a momentum indicator that analyses divergences between the price of a security and its volume flow. It aims to identify whether investors are selling (distributing), or if they are buying (accumulating).

When the Williams Accumulation / Distribution line fails to achieve a new high but the price still manages to do so then distribution is occurring. However, when the Williams Accumulation / Distribution line doesn’t reach a new low and the price does, this means that accumulation is taking place.
