NYSE Arca Integrated Feed is a real time data feed that provides a unified view of events, in sequence as they appear on the NYSE Arca matching engine. The data feed includes depth of book (with add, modify, delete orders), trades (with corrections and cancel/errors), order imbalance data, and security status messages. The product is not shaped nor throttled, so this value added data feed requires customers to establish connectivity that is sufficient to support a substantial increase in data content and bandwidth. NYSE Arca Integrated Feed helps customers overcome the challenges of determining event sequences from disparate NYSE Arca data products, increasing transparency of the specific quotes that drive trades.
