This screen finds stocks whose On-Balance Volume has been in a falling trend over the last 26 days, a medium-term sign of distribution. On-Balance Volume, created by Joe Granville, adds the day's volume on up days and subtracts it on down days, building a running total that shows whether volume is flowing into or out of a stock; Granville held that volume precedes price. Falling OBV confirms a declining price, and falling OBV with a flat price can signal a coming breakdown.
