          NYFIX AFFIRMS PREVIOUSLY ANNOUNCED DELAY IN FILING QUARTERLY
           REPORT ON FORM 10-Q AND EXPECTATION OF FILING IN A FEW DAYS

STAMFORD, CT, May 26, 2004: NYFIX, Inc. (NASDAQ:  NYFXE), a leader in technology
solutions for the financial  marketplace,  today affirmed,  as it had previously
announced  on May 17, 2004,  that there will be a delay in filing its  quarterly
report on Form 10-Q for the quarter  ending March 31, 2004,  originally  due May
10, 2004. However, as also previously announced, the Company expects to file its
Form 10-Q and its  Annual  Report on Form 10-K for the year ended  December  31,
2003 in the next few days.

As previously  announced,  the Company has appealed a notification  by Nasdaq of
noncompliance  with Nasdaq's  listing  requirements  because the Company had not
timely  filed its 2003 Form 10-K.  Nasdaq  notified  the Company on May 19, 2004
that the  Company  is not in  compliance  with the Nasdaq  listing  requirements
(Marketplace Rule 4310(c)(14)) because the Company had not timely filed its Form
10-Q and will consider such noncompliance in rendering its decision. The Company
has  requested  an  extension  to May  30,  2004  to  meet  the  Nasdaq  listing
requirements and is awaiting a decision on its request.

Upon  completion of the  Company's  filings,  the Company  expects it will be in
compliance  with its SEC reporting  obligations,  at which time the Company will
request that Nasdaq dismiss the pending delisting action against the Company and
permit the  Company's  common  stock to resume  trading  on the Nasdaq  National
Market System under the symbol NYFX.
