        NYFIX TO DELAY FILING OF ITS 2003 ANNUAL REPORT ON FORM 10-K AND
          RESTATE FINANCIAL RESULTS RELATING TO ITS INVESTMENT IN AND
                         ACQUISITION OF NYFIX MILLENNIUM


STAMFORD, CT, MARCH 30, 2004: NYFIX, INC. (NASDAQ: NYFX), a leader in technology
solutions for the financial marketplace, today announced that it will delay the
filing of its 2003 Annual Report on Form 10-K for the year ended December 31,
2003 currently due March 30, 2004. The delay is a result of the Company's
ongoing discussions with the staff of the SEC's Division of Corporation Finance
regarding the Company's accounting for its investment in and acquisition of its
80%-owned subsidiary, NYFIX Millennium, L.L.C. ("NYFIX Millennium"). As
previously announced, the discussions are part of the comment process in
connection with the SEC's review of a registration statement on Form S-3 filed
by the Company in 2003.

Based on its discussions with the SEC staff, the Company will restate its
audited results for the years ended December 31, 1999 through 2002 to change the
manner in which it accounted for the 1999 original investment in, and 2002
acquisition of an additional interest of, NYFIX Millennium. The Company is
continuing these discussions with the SEC staff relating to the complex
accounting treatment applicable to its investment in and acquisition of NYFIX
Millennium and the allocation of losses incurred by NYFIX Millennium to the
Company.

The Company is unable, at this time, to determine the full extent of changes
that will be necessary. Inasmuch as all the changes relate to non-cash items,
the Company believes that any changes to the historical accounting for its
investment in and acquisition of NYFIX Millennium will have no effect on its
current cash position or future cash flows from operations.
