Monitor feed latency, detect gaps, track data delivery across infrastructure, and measure algo response time with nanosecond precision." source: https://www.pico.net/products/corvil-analytics/market-data-analytics/ markdown_url: https://www.pico.net/products/corvil-analytics/market-data-analytics.md --- # Market Data Analytics Real-time market data quality and performance monitoring, ensuring clean, fast feeds and optimal algo response across your entire infrastructure. - Detect feed gaps, stale prices, and missing data across all venues - Monitor latency from exchange publisher through ticker plant to trading application - Measure algo decision latency (tick that triggered order to order submission) - Hundreds of market data protocols supported with monthly updates ## What is market data analytics? Market data analytics monitors the quality, completeness, and timeliness of market data feeds across trading infrastructure in real-time. Powered by Corvil, market data analytics passively captures and analyzes data flows with nanosecond precision, detecting gaps, measuring latency at each hop, and correlating trading decisions to market data ticks, ensuring optimal performance of expensive data feeds. ## Key monitoring questions answered ### Is your feed fast and clean? Ensure incoming data is complete, current, and resilient: detect gaps and monitor publisher latency. ### Does data reach your algo safely? Measure latency across infrastructure and identify congested hops or overloaded middleware. ### How quick is algo response? Track decision latency by matching outgoing orders to ticks that triggered them. ### Full Corvil Analytics platform Comprehensive trading infrastructure analytics beyond market data. ## Common use cases (and what you'll achieve) ### Optimize expensive data feeds - Identify underperforming or problematic feeds - Focus optimization efforts where they matter most ### Respond to changing market conditions - Monitor feed performance in real-time to detect issues - Detect problems before they impact trading decisions ### Reduce MTTR for market data incidents - Pinpoint exact location of gaps, latency spikes, or stale data - Accelerate troubleshooting with precise diagnostics ### Validate ticker plant and middleware performance - Measure latency and throughput at each infrastructure component - Monitor feed handlers, message buses, and network hops ### Correlate trading decisions to market data - Understand algo responsiveness by linking order submissions to triggering ticks - Measure tick-to-trade correlation across your trading environment ## Market Data Analytics FAQs ### Does monitoring impact market data performance? No. Corvil uses passive capture with network taps: there is zero impact on ticker plant performance, latency, or throughput. Monitoring is completely transparent to trading systems. ### How does Corvil measure latency from exchanges? Where exchanges provide timestamps in market data messages, Corvil compares those to local capture timestamps to measure publisher latency. For infrastructure hops, Corvil timestamps at each capture point. ### Can Corvil monitor custom or proprietary market data protocols? Yes. While Corvil supports hundreds of standard protocols out-of-the-box, custom decoders can be developed on-demand for proprietary feeds or middleware. ### What is algo decision latency and why does it matter? Algo decision latency is the time from a market data tick arriving to the algo submitting an order. This measures algo responsiveness, critical for understanding whether you're fast enough to capture opportunities before they disappear. ### How does Corvil help with A vs. B feed arbitration? Corvil monitors both primary (A) and secondary (B) feeds, comparing latency and quality. This shows which feed is faster and whether your arbitration logic is selecting the optimal source. ### Can I use Market Data Analytics without Corvil Analytics for trading? Market Data Analytics is part of the Corvil Analytics platform. It can be deployed standalone for market data monitoring or integrated with broader trading infrastructure analytics. ### What happens when Corvil detects a feed gap or latency spike? Corvil generates real-time alerts to operations teams, enabling proactive response before issues impact trading. Analytics provide diagnostics to accelerate root cause identification. ## Maximize value from your market data investment Talk to a Corvil specialist about monitoring your ticker plant infrastructure, feed handler performance, and algo decision latency across your trading environment.
