The Xetra® T7 Reference Data Interface (T7 RDI) provides reference data for products and instruments that are available for trading on the T7 Exchange’s. The reference data is delivered on a product and instrument level. Every tradable object is referenced by a unique identifier, for this reason the reference data information is absolutely essential for any trading application.

Xetra® T7 RDI publishes reference data information following FIX 5.0 SP2 semantics and are FAST 1.23 encoded. If any messages are lost, complete recovery is possible because every message is published on two identical services (A and B) with different multicast addresses (live-live concept). In the unlikely case that a message is lost on both services, participants can take advantage of the respective snapshot messages and rebuild the order book.

Xetra® T7 RDI does not offer any layout-level backward compatibility feature between two releases, and within the lifetime of a release T7 reserves the right to change the behavior of some fields in the different layouts.
