(Adds company's emailed statement saying issue resolved)
By Kanishka Singh
Oct 21 (Reuters) - Exchange operator Euronext said
that there was mix up of buy and sell orders on a number of
trades struck on Tuesday and later told Reuters that the issue
was resolved by Wednesday evening as it battled to handle
trading glitches after a huge outage earlier this week.
"It has been identified that some of the 19/10 trades sent
yesterday to the CCPs (central counterparty clearing house) had
the wrong buy/sell direction", Euronext said earlier on
Wednesday.
"Reverse trades will be sent after trading hours in order to
neutralize the error", it added.
"The issue is now solved", the company said in an emailed
statement late on Wednesday.
A series of glitches on Monday disrupted several of Western
Europe's major stock exchanges and raised concerns about the
risk of one operator hosting so many bourses.
The outage was at least the fifth major one globally this
year and one of the most widespread as exchange operator
Euronext hosts stocks exchanges from Dublin and Amsterdam to
Paris and Lisbon. It operates six major stock markets in Europe.
Trading in those locations came to standstill for more than
three hours on Monday morning due to a technical failure
impacting one of its data management systems. Though it was
resolved in the afternoon, it came back during closing auctions.
The outage was concerning for Euronext which is planning a
major expansion through a 4.3 billion euro ($5.10 billion) deal
to buy Borsa Italiana from London Stock Exchange.
Euronext will operate exchanges with more than 1,800 listed
companies and an aggregate market value of around 4.4 trillion
euros after the Borsa Italiana deal.
