EBS Market on CME Globex supports credit screened market data. Credit screened market data provides client systems price levels where there is applicable credit. The CME Globex book quantity (270-MDEntryPx) provided in credit screened market data may be a higher value than the tradeable quantity available for firms. Consequently, client systems may not be able to fill all order quantity available in the book updates.
