Shared Communication Links in an Electronic Trading System

Abstract

Certain embodiments provide methods, tangible computer storage medium, and systems of shared communication links in an electronic trading system. An example method includes determining a first network service state of a first communication network established between a first wireless trading device and an exchange and receiving a second network service state of a second communication network established between a second wireless trading device and the exchange. The first wireless trading device receives the second network state from the second wireless device via a shared communication link. The example method also includes determining an active communication network based on a quality-of-service metric calculated between the first communication network and the second communication network by comparing the first network service state and the second network service state. The example method also includes communicating market information related to one or more markets with the exchange utilizing the active communication network and distributing the market information via the shared communication link.
