Market Recovery (UDP) Feed A is used to disseminate CME Group market data snapshots for all books having activity since the beginning of the week. Market Recovery (UDP) Feed B functions as a backup in the event that Feed A becomes inoperable. Market Recovery (UDP) Feed A and Market Recovery (UDP) Feed B should not be used for arbitration.

Each packet on this feed can contain more than one Snapshot message; each message represents a market state snapshot of a given instrument. Snapshots are replayed at a constant flow of configurable packets per second.
