Daily short volume is transaction flow reported through FINRA facilities. It does not measure open short positions and is not consolidated exchange-wide volume.

Dark pool / off-exchange

FINRA OTC transparency weekly totals: shares reported by ATSs (dark pools) and off-exchange wholesalers.

Week ofATS (dark pool)Wholesalers% of VolumeTop venues

ATS and wholesaler prints happen away from the public exchanges, where a broker matches the order internally or inside a dark pool. These volumes carry no buy or sell direction and are not short volume. FINRA publishes weekly, 3 to 5 weeks in arrears.
