Williams Accumulate Distribute

Steven Achelis, in his book Technical Analysis A-Z, omits volume from the Williams Accumulation Distribution formula and several other websites/ software programs appear to follow this approach. For the benefit of investors accustomed to Achelis’ approach, we have provided both indicators.

Williams Accumulate Distribute, Achelis' version, is not a volume indicator despite the name. It is a cumulative measure of trading range for each period.

Williams Accumulate Distribute is traded on divergences. When price makes a new high and the indicator fails to exceed its previous high, distribution is taking place. When price makes a new low and the WAD fails to make a new low, accumulation is occurring.

The original indicator was created by Larry Williams.
