Top 25 of the 291 tracked names with FINRA dark pool volume this week (stock seed + active movers universe), not the whole market. FINRA reports share counts, trade counts, and a weekly dollar notional per ticker; still no per-trade prices, sizes, or sides. The dark share is the dark pool slice of the ticker's FINRA-reported off-exchange volume, not of total market volume.
How to read this
How to read this record
This page is a frozen record of one FINRA trading week, rendered from the committed weekly pack. The live weekly view (per pool, per ticker, ticker lookup) lives on the dark pool tracker, and every tracked ticker has a weekly dark pool page with its 8-week trend.
Dark pool (ATS) volume is one slice of off-exchange trading: the FINRA weekly file also carries the non-ATS channel where internalizers report. A date with no record was never captured; the record set is exactly the committed pack set.
