Abstract: Schemes for simulating a financial market are described herein. In one embodiment, a system for simulating a financial market can comprise simulated market data and non-simulated market data associated with at least one tradable security, at least one server in communication with the data, and at least one agent in communication with the at least one server. The server can be configured to process trade requests associated with the tradable securities. The agent can be configured to provide a trade request associated with a selected one of the tradable securities. The trade request can be based on applying at least one rule to the non-simulated market data and the simulated market data associated with the selected tradable security.
