An e-market can be thought of as a distributed event system where an event is generated every time the market's state changes in response to a number of human or computing agents. The paper describes a practical application of event processing in an emarket context through conventional Event Processing Systems (EPSs). A new EPS architecture that allows the integration of several existing EPSs under a unified domainspecific user interface and execution environment is proposed. We assess the performance of a prototype system for a case study in financial market surveillance and its ability to provide a common interface for two existing EPSs-SMARTS and Coral8. A discussion on the experimental results and the issues arising from the proposed EPS architecture are also provided.
