On a MEOT event, the only instances where the cancelFlag may be set to ‘true’ is when a trade is cancelled because the trade report is rejected by the TRF/ORF or ADF beginning in Phase 2a, or when the trade is cancelled but the Trade event is not linked to the related trade report due to use of reportingExceptionCode ‘C’ beginning in Phase 2c. For all instances where a trade is reported to and accepted by the TRF/ORF or ADF, and the trade report is linked to a corresponding Trade event, including those that are cancelled or busted in the trade reporting data, the cancelFlag must be set to ‘false’.
