The NYSE is postponing the previously announced industry wide contingency trading test, which was originally planned for August 9, 2008. This was to be a comprehensive test, allowing participants to test all components of continency trading, however we determined that many firms were not yet ready to do this by the original test date. To allow firms more time to prepare, the August 9th contingency exercise will be delayed until October 25th. Details about this test will be sent out about a month prior to the test.

NYSE Business Contingency Update Memo

NYSE Member Firms routing orders via CMS or CCG for NYSE Arca primary securities, ETFs, and NYSE listed Subpenny halted securities will be routed directly to NYSE Arca. This routing rule will also apply to orders entered with NYSE booth “Agency” designations. Booth directed orders will only be accepted into NYSE BBSS for stocks actively trading at the NYSE.

CMS Product Brief

In an effort to provide firms with updated and expanded business recovery capabilities, NYSE Euronext will retire our Contingency Trading Floor and instead will request, that in the event of a BCP scenario, firms redirect their order flow to the NYSE Arca trading platform. All firms that are currently connected directly to NYSE Arca or have access through a current NYSE Arca ETP (Electronic Trading Permit) holder will continue to have access to the NYSE Arca platform.

The implementation of a new Common Customer Gateway (CCG) release will begin rollout this Friday, May 30, 2008 and go live on Wednesday, June 4, 2008.

In the 1st half of 2007 the NYSE implemented systems and infrastructure changes that reduced order flow latency within NYSE Trading Systems from approximately 290 milliseconds to approximately 10 milliseconds. As part of the NYSE’s continuing commitment to reduce latency for all messaging, order flow and executions, the next system enhancement will be the implementation of a Common Customer Gateway (CCG) for interfacing to the NYSE Trading Systems, currently scheduled for the 4th quarter of 2007. This announcement provides an overview of the CCG and of the current rollout schedule, as well as an FAQ covering key aspects of the project.
