Currently, NYSE is posting market imbalances, indications of interest and trade halt/delay notifications via SIAC/MDX feed. This feed is used to regulate MOC/LOC orders going out to NYSE.

I dont think there are any rules for MOC/LOC orders on other exchanges yet , but its nice to have a message definition for mkt imbalances in FIX.

Does FIX have any plans to accommodate mkt imbalance messages in future versions ? If not , what is the common practice in the industry to “Fixify” mkt imbalance messages ?

Market imbalance information has been a part of FIX for some time.

Tag 269, MDEntryType, has value A = Imbalance which can be used to report the presence and size of an imbalance.

What is the message type to send a response to Mkt Data request ?
Or should I use MsgType=V to send imbalance report ?

You can send MarketDataSnapshotRefresh(W) or MarketDataIncrementalRefresh(X). Both have the MDEntries repeating group, which contains the above mentioned fields.
