The disclosed embodiments relate to communication of financial messages from an exchange to market participants whereby messages, or at least a portion of the content thereof, indicative of changes in the market, due to one or more trades between two or more market participants, are structured so as to reduce redundant data therein and prioritize the transmission of that portion of the message which summarizes the event and result thereof. Further, these event reporting messages may further consolidate, or otherwise be combined with, the corresponding directed reporting messages communicated to the particular market participants participating in the reported trade while preserving the anonymity of those market participants to which messages are particularly directed.
