Dear Eurex Participant,
While our constant effort is to keep the usual high availability rate of the Eurex T7 trading system, we want to support our trading participants to be prepared as best as possible for the rarely occurring incident cases. Therefore, we publish newsflash messages on a regular basis that explain the handling of various special incident cases or provide more general incident handling information.
Today, we provide you with the information needed in case a delay in the matching engine processing takes place.
1. Background information
Large processing delays in the T7 matching engine (caused e.g. by technical problems or unexpected extreme loads) may lead to the build-up of internally queued orders.
To avoid processing of old orders and to quickly recover from this delay situation, the affected products change to an internal “not tradeable” state. This rarely occurring kind of incident is automatically detected and for the relevant products the following actions are taken:
2. Best Practice
If an ETI trading session receives the message “Product_temporarily_not_tradeable”, submission of new orders should be avoided until the “Service Resumed” notification is received, since the new order flow will only exacerbate the solution of the delay problem and the orders will be rejected anyway. Deletion of non-persistent orders and quotes already took place, so any clean-up can be limited to the deletion of persistent orders, if necessary.
3. Focus days in Simulation
This focus day scenario is provided to assist participants in testing the very rare event where massive processing delays occur on a partition. For further details please check the following documents on our website www.eurex.com:
