Independent coverage of exchange connectivity, NMS plans, regulatory deadlines, and market data economics — built for the professionals who keep markets running.
Exchange notices get buried in PDFs. Regulatory deadlines slip through the cracks. Fee schedules change without warning. A 1Gbps connection quietly stops supporting multicast and someone's feed goes dark at 9:31am.
Market data infrastructure is the plumbing of financial markets. When it works, nobody notices. When it fails, trading halts, compliance teams scramble, and operations managers spend their weekends on calls with exchange support.
Market Data News exists to surface the changes that matter before they become problems.
Every material change to NYSE, Nasdaq, Cboe, CME, ICE, and 40+ global venues — connectivity updates, protocol migrations, bandwidth requirements, and port changes. Tracked in FeedWatch before they hit your inbox.
All 8 National Market System Plans tracked in one place — CTA, CQ, UTP, OPRA, CAT, LULD, ISRA, and Rule 605. Amendment filings, compliance deadlines, and operational milestones for SIP-dependent firms.
Interactive fee calculators, exchange cost benchmarks, and contract intelligence tools for market data managers. Know what you pay, why you pay it, and what alternatives exist before your next renewal.
SEC, FINRA, and CFTC rulemaking that affects market data infrastructure — from CAT reporting requirements to prediction market regulation. Tracked from proposal through implementation.
FeedWatch is our curated calendar of market data infrastructure deadlines. Every entry is researched from primary sources — exchange notices, SEC filings, and regulatory releases — and rated by severity and operational impact. FeedWatch currently tracks 30 active entries across CME, NYSE, Nasdaq, Cboe, SEC, FINRA, CFTC, and ICE.
Market Data News is an independent publication. We have no affiliation with any exchange, data vendor, or financial institution.
