Timpani is a proof of concept for the use of FIX semantics with web technologies.
This project is a prototype. Participation in the project is encouraged by FIX Trading Community members as well as from any interested GitHub users.
The demonstrated FIX semantics is in the realm of reference data about securities available to trade. A web client sends a query in the form of a FIX Security Definition Request message. The server responds with one or more Security Definition messages.
Messages between web client and server are conveyed by a WebSocket transport. The protocol enhances HTTP to leave the TCP connection open after the initial response is delivered. Then messages can be fed to the client asynchronously. This is useful for security definitions since result sets can be huge -- better to pipeline delivery of results rather than collecting it for one synchronous dump. Furthermore, some markets create new instruments intra-day. Asynchronous transport supports unsolicited push to the client.
WebSocket protocol is supported by all popular browers. In this project, the server implementation is provided by Jetty.
For this implementation, security definitions are stored in MongoDB, a popular, open-source package. It stores records as BSON documents. BSON is an performance-enhanced JSON equivalent.
