WVAD
The Williams Variable Accumulation Distribution (WVAD), developed by Larry Williams, is a volume-weighted price momentum indicator. It measures the buying and selling pressure by calculating the relationship between the number of points the market has moved from the open to close relative to the period’s entire range.
