As previously announced in the NYSE Trader Update of September 8, 2009, NYSE Amex is preparing to trade NASDAQ Listed Equities and selected ETFs on an Unlisted Trading Privilege basis starting on a date to be announced early in the first quarter of 2010.
The below Trading Technology Memo highlights the corresponding Post Trade changes in support of this effort. NASDAQ Listed Securities trading on a UTP basis will be intermingled with NYSE and NYSE Amex listed securities in the post trade comparison and after hours output. A new value will be added to the OCS uncompared file, SOS unaffirmed file and Merged Order Log files to denote a NASDAQ listed security. Recipients will be provided with the opportunity to receive test output at a time to be announced in the near future.
