FIX engines alone do not deliver a complete solution. The biggest issue with deploying FIX is completing the integration with your internal systems and testing against counterparties. Recognizing this, EPAM B2BITS has developed a range of testing and monitoring tools to reduce time to operation and cost of deployment, as well as help ensure that your FIX implementation is a high-quality service.

The FIX Automated Certification and Testing Service enables trading parties who use the FIX protocol to substantially reduce the time and cost of compatibility testing. FACTS 2.0 allows sell-side and buy-side firms to quickly and easily detect and solve a full range of problems related to violations of the FIX protocol specification and of application level conventions.

FACTS 2.0 is a script-based testing service that can be customized to mirror the FIX implementation of any sell side or exchange. It tests both session-level and application-level messages. It is interactive and offers an immediate diagnosis of any problems discovered.

FACTS 2.0 also features an administrative suite with comprehensive reports on test results and progress. The logs for any attempt conducted on all tests may be viewed in real time. This provides a complete audit trail of testing activity and results.
