Choosing between consolidated tape and direct exchange feeds requires evaluating trade-offs in latency, cost, and data depth. Consolidated tape offers broader market coverage at lower cost, while direct exchange feeds provide lower latency and deeper depth of book data for high-frequency trading needs.

Depth of book in market data infrastructure refers to the full hierarchy of pending buy and sell orders beyond the top bid and ask prices. It provides multiple price tiers, enabling firms to assess true market liquidity and design distribution architecture that supports varying data feed levels.

Managing exchange data licensing involves navigating complex vendor offerings and entitlement requirements to ensure compliance. Firms must track user entitlements, monitor distribution patterns, and select vendors that align with their specific market data types and budget constraints.

Stale quotes or missing ticks in market data feeds typically result from network latency, distribution architecture bottlenecks, or vendor data quality issues. Diagnosing these problems requires analyzing feed latency, verifying direct feed connectivity, and implementing robust data quality assurance strategies.

Designing real-time and delayed data feeds distribution requires mapping out infrastructure that balances latency requirements with cost. Firms must select appropriate market data vendors, configure depth of book levels, and implement distribution patterns that route exchange data efficiently to trading systems.

Resolving market data quality issues does not always require direct feeds, but they offer superior reliability compared to consolidated tape. Diagnosing stale quotes or missing ticks involves evaluating current vendor offerings, checking entitlement configurations, and potentially upgrading to direct exchange feeds for critical trading systems.
