NSXS operates as a wholly owned outbound order routing broker-dealer and exchange facility of the National Stock Exchange.

The deal will enable NSXS to boost operational efficiencies and address specific cross-market routing strategies.

Morgan Stanley, which has developed a complex clearing technology for cross-market trading, is planning to launch it during the first quarter of 2013.

It also provides support to broker-dealers with an array of services such as international operations for 24 hour coverage across all time zones and markets.

Headquartered in Jersey City, the National Stock Exchange (NSX) provides trading in all US exchange-listed equities and exchange traded funds (ETFs) on its NSX BLADE trading platform.
