T7 Release 7.1: Mandatory changes to reference data interfaces, Readiness Statement

Release date: 09 May 2019

040/2019 T7 Release 7.1: Mandatory changes to reference data interfaces, Readiness Statement

With this circular, we would like to draw your attention to a mandatory update regarding T7 Release 7.1. This circular is sent to Xetra and Eurex participants and therefore includes examples for both trading venues Xetra and Eurex.


With T7 Release 7.0, Xetra published Price Step Tables (aka Tick Rule Tables) via RDI/RDF only for on-book trading.


With T7 Release 7.1, Xetra RDI/RDF introduces Price Step Tables also for TES transactions.


With the current implementation, all Price Step Tables are published in the product snapshot. Each instrument snapshot/incremental references its TES Price Step Tables, if deviating from the on-book trading.


The issue with this mechanism is that applications cannot determine the usage of a specific Price Step Table until the application has received the instrument incremental (snapshot).


In order to ensure that all Price Step Tables with the full scope are available at the start of trading with T7 Release 7.1, mandatory changes to reference data interfaces have been made.


In addition, this circular announces the publication of the Readiness Statement for T7 Release 7.1. All Members are kindly requested to submit the Readiness Statement until 17 May 2019 at the latest.
