This page describes exception workflows associated with dual sided submitted for clearing. These are the alternate uses cases where a trade submitted for clearing can be rejected by CME ClearPort or can be cancelled before it is cleared or voided after it is cleared. The variation in workflows based on the transport used for submitting these trades is also described here.

This scenario illustrates submitting a dual-sided trade to CME ClearPort using MQ as a transport to be cleared at CME DCO.

The steps include:

CME ClearPort validates the trade for product, account, credit and other trade information.
If the trade failed any validations, the submitter receives a negative Acknowledgement and the trade is sent to Clearing.

Trade Submission using HTTP - Trade Rejected

This scenario illustrates submitting a dual-sided trade to CME ClearPort using http as a transport to be cleared at CME DCO. The steps include:

CME ClearPort validates the trade for product, account and other trade information.
If the trade passes preliminary validation, the submitter receives a positive Acknowledgement and the trade is sent to Clearing.
CME ClearPort then validates the trade for credit. This is an asynchronous process. The trade fails the CME hosted risk check.
The submitter may send a request for status of the trade.
CME ClearPort reports the rejected status to the submitter.
