In response to a number of queries which have been raised by Members following the hardware relate service disruption of the Eurex® system on October 11, 2011, Eurex would again like to bring the differences associated with the processing of non-persistent orders and quotes versus persistent orders and the socalled “Market Reallocation Events” to Members’ attention. These changes were initially introduced as part of the matcher improvement concept with Eurex Release 12.0.
Unlike persistent orders, where unreliable order response information is sent out after the transaction has been completed, i.e. persisted within the Eurex® host infrastructure, unreliable order response information for non-persistent orders and quotes will be sent out immediately after the order/quote has been processed by the core matching process, but before the transaction has finally been persisted.
Market Reallocation Event messages are generated and automatically sent out after a technical interruption on the Eurex back-end as soon as the Eurex® system has recovered from the technical issue. These messages provide Members with the information that all non-persistent orders or quotes stored in the order
book of a specific product have been automatically deleted and that the preliminary execution status of recently entered non-persistent orders or quotes may differ from the final execution status.
In extremely rare situations however, a technical interruption may mean that no Market Reallocation Event messages are provided at all and that gaps in reliable confirmations may occur. The circular provides Members with comprehensive information concerning the differences associated with the processing of non-persistent orders and quotes versus persistent orders in different scenarios and the associated best practices for handling Market Reallocation Events, the detection of technical interruptions
and gap detection.
