Tools for scanning dark-pool and equity-block prints

Dark-pool scanning software lists off-exchange or privately negotiated equity prints (and related block / ADF activity) that vendors surface beside or inside an options-flow dashboard. Feeds often include size, price level, delay footnotes, and filters by ticker or notional.

This is market activity software. A large dark-pool print is not a recommendation. Vendors market “smart money” and institutional zones; we do not. Copying a print is not a strategy, and this directory does not claim that dark-pool scanning improves returns.

Use this job if you want a tape of dark-pool / block activity to investigate on a chart or next to unusual-options flow. Do not use it as a substitute for understanding the structure you would actually trade.

How to use this list

Pick by fit: dark pool included on the base paid seat versus Pro-only, free or trial on-ramp, monthly dollars you can confirm on the vendor page. A listing is a job match, not a ranking. Prices below come from each tool’s verified offers on the FTT review. Confirm on the vendor site before you pay. Tools with empty affiliate_url keep an official CTA on the review page.

The grid at the bottom of this page is the catalog membership for this job. The numbered section is the live reviews whose product story honestly names dark-pool prints, levels, or equity-block / dark-pool data.

Tools for this job

1. Unusual Whales

Full-tape style unusual options flow on US-listed underlyings; paid dashboard cards list daily options and dark-pool downloads (official landing copy: dark-pool data is included in the base paid plan — confirm on current pricing cards).

US options order-flow dashboard with pricing-card labels for dark pool levels, prints, and notable flow on the same Standard seat as dealer-exposure tools. Verified offers: Standard Monthly $74.99; Standard Annual $62.50/mo billed annually; published 7-day trial. Fits traders who want dark-pool views next to flow and exposure panels.
