FIXSIM

If you provide a FIX Protocol interface to your customers, you understand the costs of testing/certifying each client and application vendor.  When your FIX specification changes or a new client is on-boarded, ensuring the client can properly implement your FIX specification prevents production level surprises.  Traditionally this is handled one client at a time using a conference line to walk through the test cases.

For example, if you provide a FIX specification for your Algorithmic Trading interface you might have dozens of clients and each one of those clients might use a different EMS/OMS.   The trading application may be a vendor or an in-house built system.  Certifying all those clients manually requires scheduling a call, manually walking through the messages being sent/received and validating the results.   With FIXSIM as a solution, your clients can run certification tests asynchronously in FIXSIM.   As a provider of the interface, you have access to reports to see all of your clients progress (pass/fail) across all the test cases and review the messages.

Using FIXSIM greatly reduces the need for manual handling of certifications, allow your support team to focus on other projects.
