Cash Market Readiness Newsflash | Updated ETI Version (8.0.1) in production and publication of updated T7 Release 8.0 EMDI and EOBI documentationCash Market Readiness Newsflash I

Dear Cash Market Members,

With this Newsflash, we would like to provide you with following updates:

1. Updated ETI Version (8.0.1) in production on Monday, 17 February 2020

As of Monday, 17 February 2020 onwards, the version number of the ETI interface in the T7 production environments will be updated from 8.0 to 8.0.1.

The updated version number will be visible to client applications in the fields “DefaultCstmApplVerID” (1408) and “DefaultCstmApplVerSubID” (28763) of the ETI Logon Response.

Client application software which explicitly checks for a specific ETI version returned in the Logon Response message needs to be prepared to accept 8.0.1 in production from 17 February 2020 onwards.

As of 17 February 2020, the fields“DefaultCstmApplVerID” (1408) and “DefaultCstmApplVerSubID” (28763) in the ETI Logon Response will be populated as follows:

 DefaultCstmApplVerID  DefaultCstmApplVerSubID
Derivatives markets / Eurex 8.0.1       D0003
Cash markets / Xetra  8.0.1   C0004

The Logon Response containing the new version number can be tested in the T7 Simulation, as the updated version of the ETI software is already in the T7 8.0 Pre-Production and in the T7 8.0 Simulation environment since 31 January 2020.

The exact details of the changes for Cash Markets / Xetra which have been implemented with the updated version of the interface (V8.0.1,) and which are relevant only for the Börse Frankfurt migration, can be found in the change log of the updated document “T7 Enhanced Trading Interface - Cash Message Reference v.8.0.1-C0004” (published on 15 January 2020 along with new layouts) on the Xetra website www.xetra.com under the following link:

For Derivatives markets / Eurex there is no change at all in the ETI interface (no new interface layouts will be published), as it remains on “D0003”.

Full backwards compatibility for both cash and derivatives markets, ETI clients implementing interface version v8.0 is provided, and therefore no further action for these clients is required.

2. Publication of updated T7 Release 8.0 EMDI and EOBI documentation

The updated documents “T7 Market and Reference Data Interfaces - Manual v8.0.3”, “T7 Enhanced Order Book Interface - Manual v8.0.3” and both XML Representations (EMDI, EOBI) have been published on the Xetra website www.xetra.com under the following link:

Please note that the XML Representations received a new version number to match the documentation, but do not contain any relevant changes to the XML structures.

The main changes are as follows:

  • EMDI: Updated section about trade reversal, as neither “Exchange Last” nor the “Closing Price” will be updated any more because of a trade reversal.
  • EOBI: Changed description for TrdRegTSExecutionTime (21001) from Trade Reversal message, as neither “Exchange Last” nor the “Closing Price” will be updated any more because of a trade reversal.

Please see the „Change Log” in both documents for a full list of changes.

3. Publication of updated T7 Release 8.0 Börse Frankfurt documentation

Please be informed that the following T7 Release 8.0 documents referring to Trading Interfaces have been updated: 

  • T7 FIX Gateway Manual v.8.0.1
  • T7 FIX Gateway Fiximate v.8.0.1
  • T7 FIX Gateway FplRepository v.8..0.1

and can be found on the website www.xetra.com under following link:

The changes are:

(1)    The description for the field SettlCurrFxRate (155) has been enhanced with the following text:

The exchange rate as a multiplicative factor, converting the settlement amount given in instrument currency into the settlement amount given in settlement currency. The multiplicative factor is calculated as settlement currency exchange rate to euro, divided by instrument currency exchange rate to euro.

(2)    New Valid-Value for the Mass-Cancellation events

MassActionReason (28721) = 118 (Instrument knock out has been reverted)
