Use the HeartbeatMessage only if you need to keep a firewall open - as it will incur some performance penalty as a response will block your connection.
For these matched bets, you will receive on the Order Stream both a uo for the affected bet and the relevant updates to mb or ml reducing the matched volume at the original matched price and adding volume at the new reduced price.
