MDP 3.0 - Cleared Volume
Cleared Volume data blocks contain the number of contracts that have been through the clearing process for an active instrument for the previous trading day. Tag 5796-TradingReferenceDate indicates the Cleared Volume trading session date, which is the previous trading day. Tag 279-MDUpdateAction will be set to 0 = New and tag 269-MDEntryType will be set to B = Trade Volume. Tag 271-MDEntrySize will contain the Cleared Volume.
Cleared Volume is updated once per day throughout the trading week. Client systems can leverage the Security Definition (tag 35-MsgType=d) message to recover the last published cleared volume for an instrument. On Sunday start, the Security Definition (tag 35-MsgType=d) Message is published initially to the Instrument Definition feeds and the Market Data Incremental Refresh feeds without tag 5791-ClearedVolume. Once Cleared Volume is sent in the Market Data Incremental Refresh message, the value of Cleared Volume from tag 271-MDEntrySize is placed on the Security Definition (tag 35-MsgType=d) Message in tag 5791-ClearedVolume and maintained on the Instrument Definition feed. As cleared volume updates are disseminated, once per day, on the Market Data Incremental Refresh feed, the value of tag 5791-ClearedVolume is updated.
If Cleared Volume is 0, tag 5791-ClearedVolume=0.
