While submitting trades, identifying the parties or entities involved in the trade is essential to Clearing. The clearing account, also referred to as the customer, is one of the most important party roles for trade submission to clearing. Details about retrieving entity information from CME ClearPort are available in the CME ClearPort Entity Reference API.

While submitting trades, identifying the Instrument being traded is critical. CME ClearPort allows trading of outrights and spreads. The submitted trade must contain all the attributes needed to identify a contract. Details on getting Product reference information from CME ClearPort are available in the CME ClearPort Product Reference API.

Submitting Account Aliases

The API allows submission of account aliases into CME ClearPort instead of the Clearing account with all the qualifying Party Roles. It encapsulates the Trading firm, Clearing account number and Clearing Firm, allowing use of an external reference for specifying an account. Allowing aliases to be defined at these levels, the API provides the flexibility for trading firms and platforms to represent the account as they know it. It supports submission of different types of aliases into the API. Currently a Trading firm or a platform may define unique aliases for clearing accounts in CME ClearPort.

Additionally, CME Group automatically assigns a unique alias to each existing account, as well as any newly created accounts. CME Group publishes these account aliases via the ClearPort API for Entity Reference Data. Trading firms and platforms can submit trades using this CME alias in lieu of specifying a clearing account number, trading firm, and clearing firm. If the trading firm or platform uses the CME Group alias to submit a trade, the resulting acknowledgment likewise uses this alias in lieu of a clearing account number, trading firm, and clearing firm.

The following forms of aliases are supported:

Trading Firm Assigned Alias

A Trading firm or an Asset manager can assign an alias to the Clearing Account. The source attribute identifies whether the alias being sent is a custom alias. The trading firm is identified in the Sub tag.

Platform Assigned Alias

CME ClearPort also supports submission of a platform assigned alias. The source identifies whether the alias being sent is a custom alias. The platform is identified in the Sub tag. 

CME Assigned Alias

CME ClearPort also supports submission of a CME assigned alias. The source identifies whether the alias being sent is a custom alias. The platform is identified in the Sub tag. 

Submitting Legal Entity Identifier (LEI)

Each counterparty to a swap subject to the jurisdiction of the CFTC must be identified in all recordkeeping and swap data reporting under Part 45 by using a single legal entity identifier, known as LEI.

Until the FSB endorses the recommendations, the CFTC is referring to the identifier to be used in reporting under the CFTC rule as the CFTC Interim Compliant Identifier (CICI).

The ClearPort API will not make the distinction between LEI and CICI. 

Submitting Reporting Counterparty

The Reporting Counterparty (RCP) is the party to a swap with the responsibility to report a publicly reportable swap transaction as soon as technologically practicable to a Swaps Data Repository (SDR) in accordance with the Dodd-Frank Act. Under this Act, one party must bear responsibility to ensure that the trade is reported.

In their rulemaking, the CFTC has created a hierarchy whereby:

• Swap Dealers (SDs) always report when trading with Major Swap Participants (MSPs) and end users, and

• MSPs always report when trading with end users.

The Reporting counterparty can be specified along with the Customer Account or with the Trading firm. The Reporting counterparty is identified in the Sub tag.

Submitting Other Party Roles

Use the following party roles (R) in the Party block when submitting a dual-sided trade. Refer to the validation rules when submitting Party roles.

Party Role Validations

•  

  • The Customer account information is required.

  • Participants can either submit an account alias or a fully qualified account.

  • If an alias is provided, it has to indicate if the alias is Trading firm assigned, platform assigned, or CME assigned.

  • If the participant submits an account (not alias), the clearing firm will have to be specified.

  • A Broker Firm (Party role 30) is required for brokered trade submissions into the CME ClearPort API. The broker firm must be permissioned to submit trades for the specified accounts or the trade will not be accepted.

  • If a Broker (Party role 30) is specified on the trade, a Broker User (Party role 62) may be required. The Broker User will have to be a valid User ID in ClearPort.

  • Asset Manager Firm (Party role 49) / Trading Firm (Party Role 7) are optional for non-brokered trade submissions. 

  •  

    • If an Asset Manager Firm is assigned to the referenced account(s) then it will be persisted as the buyer/seller principal for the applicable side.

    • If an Asset Manager Firm is not assigned to the referenced account(s) then CME ClearPort will verify that the Account Owner / Trading Firm has active trading rights.  

    •  

      • If active trading rights exist, the Trading Firm will be persisted as the buyer/seller principal for the applicable side. 

    •  

      • If active trading rights do not exist, the trade will be rejected.

  • If an Asset Manager (Party role 49) is specified on the trade, an Asset Manager User (Party role 36) will be required. The Asset Manager User will have to be a valid User ID in ClearPort.

  • If a Broker submits a trade using an account(s) with an Asset Manager assigned, the Asset Manager firm becomes a part of the trade and will appear as Party Role 49 on the applicable side or allocation.

  • A Trader ID (Party Role 36) indicating entering trader, is required for all exchanges except CME and CBOT. In some cases, an Asset Manager User ID may be sepcified in Party Role 36 to satisfy the Trader ID requirement. CME ClearPort will validate the User ID in Party Role 36 to ensure that the Trader ID specified is a valid Trader or Asset Manager for the specified Account.

  • The Trader ID will not be validated if the Source of the Trader ID is a Custom Source (Src="D").

  • The reporting counterparty can be specified as a Sub Tag of a Customer Account or a Sub Tag of the Trading Firm.
