DEX 23.2

A new FT DEX, version 23.2, is being introduced on 11th July 2016. This should not have very much impact on your testing, as there are no new or amended messages, but two messages are being withdrawn:

FCSQ CCP Security FT Retrieve
FCSP CCP Security FT Response

These messages will also be removed from the Simulator on this date.
Removal of Legacy Overnight Gilt DBV Processing

Euroclear recently announced that the legacy overnight gilt DBV processing service will no longer be available on the CREST system as from Monday, 3 October 2016. However, the legacy overnight equity DBV processing service will continue to be supported after this date.

If you are currently using the legacy overnight gilt DBV functionality (a DBV without a return date), you can replicate this business function by inputting a return date of the next business date in the DBV instruction.

This functionality can be tested in the Simulator prior to client testing with Euroclear.
