Market Data Protocols And Reporting Standards

Market data protocol and reporting standard terms describe the formats, feeds, tags, and reporting workflows used to move trading, market, and disclosure data between systems. This branch covers FIX, high-speed data feeds, real-time information, real-time reporting, and XBRL.

Use these pages when a quote, execution message, filing tag, data export, reporting feed, or compliance record depends on the format or timing of the data.

What This Branch Covers

Decision Lens

Start with the data record. Determine whether the issue is message syntax, field mapping, latency, source venue, report tag, timestamp, entitlement, or downstream system use. A format standard helps only if the fields are complete, current, and mapped to the correct finance event.

Evaluation Checklist

• Identify the protocol, feed vendor, system, instrument, field, timestamp, report period, and receiving application.
• Separate source data from transformed data, calculated fields, reporting tags, alerts, and dashboard summaries.
• Check message rejects, stale fields, mapping errors, delayed feeds, entitlement limits, and version changes.
• Reconcile material reports to source messages, exchange records, issuer filings, broker records, or regulator records where available.
• Treat accounting, securities reporting, trading, regulatory, legal, and investment conclusions as professional-advice areas.

Common Mistakes

• Assuming real-time data is complete, executable, or error-free.
• Treating a standardized message as proof that the underlying trade or report is correct.
• Comparing feeds without checking timestamp precision, venue coverage, and entitlement rules.
• Reviewing XBRL data without checking tags, taxonomy version, and source filing context.
