Access is controlled contractually (registered US broker-dealer subscribers only) and at the network layer (private cross-connects into Equinix NY4). Identity on the wire is carried by FIX session and order-level identifiers rather than a bearer credential.' schemes: - name: subscriber-eligibility type: contractual applies_to: IntelligentCross FIX Order Entry API description: IntelligentCross only permits registered US broker-dealers to be subscribers.
