¹ ~1,600 of 6,789 names clear the quality gates; the rest show a dash. ² List or reported prices as of August 2026, subject to change, converted to a monthly figure where a vendor bills on another term: Finviz Elite is ≈$39.50 month to month and ≈$24.96 a month on its annual plan, WhaleWisdom is ≈$90 a quarter, and SPZCO’s own $29.99 is the monthly plan ($299 a year works out lower). Capability reads are our good-faith view, and legacy terminals cover far more in real time. Koyfin, Fiscal.ai, Yahoo®, Finviz, WhaleWisdom and Unusual Whales are their owners’ trademarks; SPZCO is unaffiliated with any of them.
