Abstract: Methods, systems, and computer-readable media for providing a rule based exchange simulator are presented. A plurality of rules may be received at an exchange simulator that define how orders should be processed at the exchange simulator. The received rules may be stored, for instance, at a rules engine. For example, rules may comprise a fill rule, a cancel rule, a reject rule, a no acknowledgment rule, and a market data rule. An order that comprises a stock exchange order may be received at the exchange simulator. For example, an order may comprise a buy or sell order for a particular instrument, such as a stock, and may comprise a particular quantity. Based on the one or more rules stored in the rules engine, the received order may be fully filled, partially filled, or not filled.

Abstract: Embodiments of the invention are directed to systems, methods, and computer program products for configuring and managing multiple gateway connections in a network. The system is configured to receive, using an Enterprise Messaging System (EMS) gateway, an order from one or more clients using a distributed network of servers, wherein the order comprises a Financial Information eXchange (FIX) protocol, wherein the FIX protocol comprises one or more fields, wherein each of the one or more fields comprises a tag value indicating a meaning of the field; validate the order received from the one or more clients using a central FIX engine validator; transform the order received from the one or more clients into one or more corresponding actions to be executed with the financial market; and transmit, using a FIX gateway connection, the transformed order to the financial market; and execute the corresponding action with the financial market.
