IBM, software firm to take Linux-based system to Street

IBM Corp. (IBM) plans to announce Tuesday that the electronic trading service
that supplies brokers with data from the New York and American stock
exchanges is shifting its key applications to Linux.

The big move is being made by the Securities Industry Automation Corp., or
SIAC, and a related unit, Sector Inc.

SIAC runs the NYSE’s and Amex’s computer trading and messaging systems. It
supplies brokers and member firms with constant streams of data on buy and sell
transactions. The system handles about 4 to 5 billion trades daily from the
exchanges.”
