   NYFIX TO DELAY FILING OF ITS 2004 ANNUAL REPORT ON FORM 10-K AND MANAGEMENT
                           REPORT ON INTERNAL CONTROL

STAMFORD, CT, MARCH 30, 2005: NYFIX, INC. (NASDAQ: NYFX), A LEADER IN TECHNOLOGY
SOLUTIONS for the financial marketplace,  today announced that it will delay the
filing of its 2004 Annual  Report on Form 10-K for the year ended  December  31,
2004  currently  due March  31,  2005.  The  delay is a result of the  Company's
previously  announced  discussions  with the Securities and Exchange  Commission
regarding its accounting for previously issued stock options.  As a result,  the
Company also announced that it will delay the filing of its Management Report on
Internal Control as required by the  Sarbanes-Oxley Act of 2002. The Company had
anticipated  filing its  Management  Report on Internal  Control by the extended
filing  deadline of April 30, 2005.  However,  due to the delay in the filing of
its  Form  10-K,  it no  longer  qualifies  for  the  automatic  forty-five  day
extension.

As previously  announced,  the Company expects to restate its audited  financial
statements  for the years ended  December 31, 2003 and 2002 included in its 2004
Annual  Report on Form 10-K and is  evaluating  whether it needs to restate  its
unaudited  results for each of the first three  quarters of 2004. The Company is
also reviewing the impact of such accounting changes on the Company's historical
accounting  of its deferred tax assets.  Inasmuch as the  adjustments  primarily
relate to non-cash items, the resulting restatement will have no material effect
on the Company's current cash position or cash flows from operations.

The Company  intends to  exercise  its best  efforts to resolve the  outstanding
items and file its 2004 Annual Report on Form 10-K and its Management  Report on
Internal Control as soon as possible.
