Saturday Maintenance Window Processing Overview

The following section outlines Saturday maintenance processing for 24/7 trading.

Saturday Shutdown and Startup

Shutdown

At the beginning of the maintenance period, client systems will receive a MDP 3.0 - Security Status. Then CME Globex will send the iLink messages to iLink Execution Report - Elimination orders. Next, client systems will experience MDP multicast, TCP iLink and Drop Copy disconnections. At this point, clients should reset their books. CME Group recommends that clients and vendors restart their applications at this time and go through their own restart processes.

Startup

iLink order entry, Drop Copy and market data sequence numbers reset to 1 during the Saturday startup cycle. Client systems will re-establish connectivity to the MDP multicast groups and receive the following startup messaging:

The MDP 3.0 - Market Data Snapshot (tag 35-MsgType=W) messages on the Market Recovery feed are deleted for the impacted 24/7 channel. Tag 83-RptSeq for Market by Price (MBP) book updates resets to 1 for each instrument repeating group.
CME Globex disseminates incremental real-time market data for that channel and client systems can process the data. A MDP 3.0 - Market Data Incremental Refresh (tag 35-MsgType=X) message will be sent with an empty End of Event indicator if no other information is available. If session statistics are available, they will be republished via the normal Incremental Refresh messaging:
1. Current session trade volume
2. Price levels in the order books
3. Highest and lowest trade
MDP 3.0 - Security Status messages containing market states (per instrument group) will be sent for the 24/7 channel. Then any instrument states that are different from the instrument group state are sent (e.g., Forbidden/Halted instruments).

Pre-registered administrative information will be removed during the Saturday maintenance window. Clients must re-submit their iLink Party Details Definition Request following the pre-open on Saturday.

24/7 Maintenance and Trading Schedule Examples

This section provides examples for 24/7 trading.
