Off-exchange context
Dark pools are one half of off-exchange trading. In the week of Sep 14 to 18, 2026, FINRA reported 263.2M ONDS shares traded off the exchanges in total: 32.1M through dark pools and 231.1M through the non-ATS channel (internalizers and wholesale market makers reporting straight to FINRA). Dark pools carried 12% of that off-exchange total. This is a share of FINRA-reported off-exchange volume, not of total market volume; the FINRA weekly file does not include exchange volume.
How to read this
Dark pools are private alternative trading systems that match institutional orders without displaying them to the public first. The weekly FINRA file shows how many ONDS shares and trades each dark pool reported, aggregated for the whole week. It carries no prices, no trade sizes, and no direction, so it cannot say whether the volume was buying or selling. Use it to see where hidden liquidity concentrated, and pair it with the live chart for price context.

Why is this data weeks old?
FINRA publishes dark pool volume weekly, on a delay. The week of Sep 14 to 18, 2026 was first published Oct 19, 2026, and nothing fresher exists until FINRA publishes the next week. We state the lag plainly instead of dressing delayed data up as live.
Does heavy dark pool volume mean big investors are buying?
No. Dark pool volume is hidden liquidity: it says where institutions chose to trade away from the lit exchanges, nothing about direction. FINRA reports share counts and trade counts, not prices, sizes, or sides. A week of heavy dark pool volume can accompany accumulation, distribution, or two-sided market making.
