The London Stock Exchange has blamed a “technical software issue” for a one-hour delay to the opening of equity trading on Thursday.
The glitch, which has now been resolved, meant the opening auction for the U.K.’s main bourse began at 9 a.m. London time, or 4 a.m. U.S. Eastern Time, rather than the usual 8 a.m.
“London Stock Exchange identified a technical software issue that was preventing some members from entering orders into the pre-open auction system prior to the standard market opening time,” said spokespeople for the exchange’s operator, London Stock Exchange Group , in an emailed statement.
“To preserve the integrity of the market and to ensure orderly trading, London Stock Exchange decided to delay the market open while the matter was investigated and informed market participants accordingly.”
After the software problem was resolved, members were notified at 8:40 a.m. that trading would start at 9 a.m., the spokespeople added, also saying that trading has been “operating normally” since then.
As traders waited for the open, they joked on Twitter that at least they hadn’t lost any money yet...
...and suggested the exchange operator’s shares were due for a selloff:
Shares in LSEG were recently up 0.1% after earlier trading in the red.
