Cboe Futures Exchange Announces Block and ECRP Trade API

Cboe Futures Exchange (CFE), a wholly-owned subsidiary of Cboe Global Markets, announced that it will enable the submission and acceptance of Block and Exchange of Contract for Related Position (ECRP) trade notifications via a new API service called Block/ECRP Trade Reporting.

According to the press release, the new API will support all existing trade notification entry, acceptance, and rejection functionality currently available in the Block/ECRP Reporting Tool accessed via the US Customer Web Portal. CFE Authorized Reporters are the only users allowed to submit and accept Block and ECRP trade notifications.

The new API will enable submitters to enter new Block and/or ECRP trade notifications with the same fields available today through the tool on the Web Portal and enable counterparty acceptance or rejection of Block and/or ECRP trade notifications.

In addition, the API will enable delivery of a Reference ID, which will also be emailed to the contra party, in response to a Block or ECRP trade notification submission.

As with the existing Web Portal tool, the new API will not allow submitters of the original trade notification to modify or cancel that submission.

CFE Authorized Reporters may use either the API or the Block/ECRP Trade Reporting Tool to accept the trade notification. Likewise, an Authorized Reporter may use the API to accept a trade notification even if the originating trade notification was submitted through the Block/ECRP Trade Reporting Tool.
