EP019 – FIA Extensions PartyRole Extension

This proposal adds PartyRole enumerations for Trader Pneumonic, Site Location ID and Session ID. The information is needed on cleared trade confirmations so that clearing firms can identify the original routing session, source location and executing trader information associated with a trade.

The problem is that session-level identifiers such as SenderCompID, SenderLocID and SenderSubID need to survive beyond the original electronic-order session and be passed through clearing. The proposal addresses this by representing those business identities in the reusable Parties component rather than relying solely on session-header fields.
