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
e-market context through conventional Event Processing Systems (EPSs). A new EPS architecture that allows the integration
of several existing EPSs under a unified domain-specific 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.

step is not required when selecting SMARTS since it has the ability to process real-time market data as well.
