Originally released in 2008, MarketDataPeaks was the first public website to provide a real-time visualization of aggregated market data message rates across United States exchanges. It is widely used by fintech professionals to inform operational awareness and capacity planning decisions. MarketDataPeaks was significantly enhanced in 2018 to build upon a decade of technological advancements and to improve the accuracy and precision of rate measurements. Data rate measurements are performed by next-generation Exegy appliances that feature hardware-based timestamping, clock synchronization, and rate measurements. The Exegy appliances are located in the Equinix NY4 colocation facility.
In addition to more accurate measurements, the new MarketDataPeaks provides measurements of micro-bursts of market data - the amount of data arriving in a one millisecond interval. Note that the burst rates reported by MarketDataPeaks are normalized to "per second" values for easy comparison with the standard rate measurements - the amount of data arriving in a one second interval. The burst rates measured by MarketDataPeaks can be ten times larger (or more) than data rates measured in a one second interval. This information is essential when designing systems that process real-time market data feeds without data loss and with minimal variance in processing latency.
The new MarketDataPeaks also provides a broader set of metrics including packet rates, in addition to message rates, for more accurate network capacity planning purposes. Messages per second primarily determines the number of events per second that market data consumers must process. Packets per second helps determine the capacity required by network devices such as switches and the interface cards used by servers.
The public MarketDataPeaks site provides message rates, message burst rates, packet rates, and packet burst rates for two sets of US market data feeds - the Securities Information Process (SIP) feeds and the proprietary (direct) feeds from the major equities and commodities exchanges. After registering with the site, users gain access to fine-grained control over the real-time displays with the ability to view metrics on an individual feed basis, as well as select any permutation of data feeds within each set. In additional to graphical plots of today's market data rates, MarketDataPeaks provides historical peak rate information in tables.
