Simulate global FIX venues with ease and flexibility

Esprow GSP, or Global Simulators Pack, is a bundle of more than 60 FIX simulators for existing venues and markets.

Each simulator supports the venue's FIX messages, custom tags, and orderbook behavior. They can be deployed on a server and used by multiple users concurrently. They support multiple FIX sessions, concurrently, whether unencrypted or configured with SSL/TLS certificates.

All simulators support standard order-entry functionality through the following messages: NewOrderSingle [D], OrderCancelRequest [F], OrderCancelReplaceRequest [G], OrderStatusRequest [H]. Simulators also check for many common conditions and mistakes, like, for example, session-level validation errors, duplicated ClOrdIDs, and many others. All simulators are pre-configured with special behavior and symbols, like, for example, special symbols that trigger full-fills, partial-fills, or rejections.

Simulators are fully configurable by the user and can be extended with custom behavior and scenarios to fulfill the most disparate testing requirements.
