Party Details List Request
The new Party Details List Request message (tag 35-MsgType=CF) is used to request all of the Party Details Definition information for a particular Firm ID.
- Party Details List Request message should be sent only to the Service Gateway.
- Party Details List Request message can be used to request all Party Details Definitions for a firm or specific Party Details Definitions belonging to that firm
- Customers can submit a Party Details List Request message and receive the Party Details List Report message (tag 35-MsgType=CG) detailing active Party Detail Definitions.
- The Party Details List Request message should be used in these circumstances:
- To confirm submission of Party Details Definition messages sent earlier to the Service Gateway. This can be done:
- Sunday at the beginning of the week before the start of trading but after Party Details Definition messages have been sent earlier in the day
- Before the start of each trading session
- After the close of each trading session
- Anytime there is a need to confirm which Party Details Definitions have been registered with CME
- To confirm submission of Party Details Definition messages sent earlier to the Service Gateway. This can be done:
- There are two types of the Party Details List request:
- by Executing Firm - Request all Party Details for a single firm using tag 1657- NoRequestingPartyIDs repeating group
- by PartyID - Request specific Party Details using tag 453-NoPartyIDs repeating group
Noteinfo |

Customers can submit a Party Details List Request message either by Executing Firm or PartyID. Both types cannot be presented in the same Party Details List request message. |

Drop Copy message payloads will have full details of both administrative and business information regardless if the party details were pre-registered or sent prior to the business message, e.g. New Order Single, Order Cancel Replace Request, etc. |
Each Party Details List RequestID will be unique per firm. If a firm is hosted on more than one session, the same Party Details List Request ID can be used across all sessions.
For Example: Executing Executing Firm="123" is hosted both Session ID = "ABC" and Session ID = "XYZ". PartyDetailsListRequestID = "1001", created by session ABC, can be used on both sessions.
