dark pool & off-exchange short volume — regulatory data, daily aggregate · published T+0 evening AS OF 2026-11-06

Dark pool and off-exchange short volume

Off-exchange short volume is the share of a session's off-exchange volume — the trades executed away from the lit exchanges on ATSs ("dark pools") and by internalizing dealers, reported to FINRA — that was sold short. It comes from FINRA's Reg SHO daily publication: a per-session aggregate published the evening of the trade date, not a live print tape, and its base is the off-exchange tape, not consolidated volume. A high ratio is a positioning magnitude, not a direction.

FINRA Reg SHO daily short-sale volume, 2026-11-06 session — short-vol ratio = shares sold short ÷ shares reported to FINRA facilities (ATS and internalized prints), so the base is off-exchange volume, not consolidated volume. A daily aggregate published the evening of the trade date. Session change column: settled closes as of the 2026-10-29 session — a different session than the short-volume tape.

ATS venues — weekly board

FINRA weekly per-symbol ATS (dark pool) totals for the latest fully published week, with week-over-week change, ranked by ATS share volume among liquid names (same minimum average daily dollar volume as the daily board). FINRA publishes each week on a lag of about two weeks for Tier 1 NMS stocks and about four weeks for other securities. (the same real dollar-volume floor). Weekly data, published on FINRA's own multi-week lag (~2 weeks Tier-1 NMS, ~4 for the rest) — weeks behind the tape by regulation.

FINRA weekly per-symbol ATS ("dark pool") volume, week of 2026-09-28 — the latest fully published week; FINRA releases each week on a lag of about two weeks for Tier 1 NMS stocks and about four weeks for other securities. WoW compares the 2026-09-21 week; % of ATS tape divides each name into the week's whole stored ATS total. Session column: settled closes as of the 2026-10-29 session — a daily vintage, not the ATS week.
