Imperative Execution is a New York financial technology company and the parent of IntelligentCross, an SEC-registered US equities Alternative Trading System (ATS) that applies machine learning to order matching and price discovery. IntelligentCross operates a non-displayed Midpoint book and ASPEN, a full limit order book with optional displayed capability that is split into three independent books by fee model (Fee/Fee, Maker/Taker, Taker/Maker), all under MPID INCR, with primary matching engines in the Equinix NY4 data center in Secaucus, New Jersey. Registered broker-dealer subscribers reach the venue for order entry over FIX 4.2 across Pico cross-connects, and the venue publishes its own IQX market data feed - a binary, multicast-UDP full depth-of-book and execution feed whose message specification, recovery/rerequest specification, daily symbol mapping file and sample PCAP captures are all published openly.
