Simulate FIX protocol message exchange.
What is a FIX Simulator?
A FIX simulator is a tool used for testing FIX Protocol integrations. The FIX protocol is a community driven standard that outlines the message format and procedures for exchanging financial information. A FIX Simulator can provide acceptance of a FIX connection (act as a FIX Acceptor) or initiate a connection (act as a FIX Initiator).
A FIX simulator is required to act as “the other side of the trade”. For instance, if you are an asset manager, you will need a FIX simulator to act as a broker/dealer or exchange to simulate order execution. Conversely, if you are a broker/dealer, you need a FIX simulator to behave as a client connecting and submitting orders to you.
How FIXSIM is different
FIXSIM is a web-based solution that can either act as a FIX initiator or acceptor (or both!). With no software to download and simple month to month plans, get immediate access to a testing endpoint for your needs.
We support equities, futures/options, foreign exchange, fixed income, and other asset classes with ANY version of FIX. From our web portal, quickly build out any FIX session and connect your application.
With our web-based portal, easily configure and monitor FIX message traffic. See orders and execution messages and control how orders are executed.
See direct FIX message traffic and view messages in raw FIX format as well as translated tag numbers and values.
Our trade blotter views provide you with a trader's viewpoint on active orders. See order quantities, average prices, and execution values. Take action on orders in the blotter with actions like: Partially fill, cancel, correct prices, and more right from the web portal.
Having an automated solution to FIX testing provides assurance you maintain compliance with FIX integrations. Build, design, and fun repeatable FIX test cases with FIXSIM.
Use our web portal to build rules and actions to respond to messages. For example, if an order is received in FIXSIM for IBM, acknowledge the order, partial fill, and cancel the remaining quantity. Configure your FIXSIM sessions to your testing scripts to provider user free automation.
We offer our Web API to directly control FIXSIM via RESTful calls (e.g. Curl). Using Swagger/OpenAPI, our API is fully documented and can easily generate a client in any language (C#, Java, Ruby, more). This provides you with the full power of FIXSIM to be controlled by your application.
