An institutional dark pool intelligence engine that decodes hidden order flow across 40+ ATS venues in real-time. Surface-level retail data shows one story — MK Flow reveals the massive accumulation and distribution happening underneath, giving you the asymmetric edge that separates informed capital from noise. Track block trades exceeding $1M, detect unusual options sweeps, and identify the footprints of smart money before the crowd catches on. The platform aggregates data from FINRA-reported ATS venues, options exchanges, and block crossing networks into a unified signal dashboard.
