Eurex Clearing Readiness Newsflash | C7 Release 12.1: Simulation focus days for Trading Unit > 9999,9999 via corporate action
With this Newsflash, Eurex Clearing informs Clearing Members, ISA Direct Clearing Members, Disclosed Direct Clients and vendors about dedicated focus days during the C7 Release 12.1 simulation related to corporate actions requiring a Trading Unit > 9999,9999.
Background
With C7 Release 12.1, it will be possible to define higher values for the Trading Unit at contract level when triggered via the capital adjustment process.
Currently, the Trading Unit is restricted to values up to 9999,9999. With the Release, the Trading Unit will be extended to decimal (10,4), corresponding to a maximum value of 999999,9999.
To support Member readiness and testing of this enhancement, to ensure your organization is fully prepared for the upcoming enhancement, we are providing dedicated focus days in the C7 Release 12.1 simulation.
