FINRA off-exchange short volume for ONE ticker, ranked against that ticker's own recent history — pass ticker for any name we carry, or omit it for the whole published set alongside index-mover earnings, the VIX term structure and options volume. A ticker we do not carry is REFUSED BY NAME with the covered list, never answered with another instrument's number. ⚠ READ SHORT VOLUME AS ONE-SIDEDNESS, NOT AS A BEARISH VOTE: most off-exchange short prints are market makers hedging, so a high reading says the tape was one-sided, not that anyone is positioned for a fall. The rank is a percentile over that ticker's last 120 sessions; under 20 samples it reports rank: null rather than a number computed off five points. Free, and updated through the session.
