Details

Configuration

The client needs to provide clear requirements as to which of the various Market Data Groups they wish to subscribe against. The table EBS on CME Globex Market Data Services Overview should be referenced and provides details such as:

  • Conflation Interval
  • Book Depth (see also PassthruFields, below)
  • Credit Screened, or not
  • Etc

SecurityGroup

The SecurityGroup field is used to identify eFix and Precious Metals instruments. If the SecurityGroup is populated on SecurityStatus messages, it will be expected to be populated in all client MarketDataRequest messages.

eFix

The SecurityGroup field must be populated as per the format "BaseCCY/TermCCY <Benchmark Fixing details>"

Not all combinations of Benchmark/fixing time might be available for all instruments. This will be validated at runtime. 


MarketData subscriptions for eFIX instruments are of limited value, since there is by definition no published book. However the SecurityStatus information does still provide the user with  Important SecurityStatus information.


For products which have an early trade date roll which moves the trade date to the following week, eg, PHP, CME will not publish updated instrument definition until start of the new session on Sunday.

In this case, the LegSettlDate and MaturityDate will be be NULL for these products for the intervening period from the trade date roll to Friday close.


Due to Credit exhaustion, EBS can send a duplicate new price level or a change or a delete event for a price level that did not exist in the book. MarketFactory book manager will handle the unknown updates as described in the table below:

ScenarioEBS MDUpdateAction [to MF]MF MDUpdateAction [to Client]

Unknown Delete
