Report: NYSE ETF trading venue hit by software glitch

NYSE Arca suffered a 15-minute trading outage Dec. 19 resulting from a weekend software update, The Wall Street Journal reported, citing New York Stock Exchange spokeswoman Kristen Kaus.

The exchange for exchange-traded funds in the U.S., which is part of Intercontinental Exchange Inc.'s NYSE, sent a systems alert at 9:08 a.m. ET on Dec. 19 after identifying the issue. Subsequently a follow-up alert was sent at 9:23 a.m. E.T. saying the issue was resolved.

However, later, NYSE Arca alerted the market that customers were receiving unsolicited cancellations, and it halted trading from 10:50 a.m. to 11:05 a.m. E.T. Trading resumed at 11:06 a.m. after the weekend software update was rolled back, the Journal reported.

Kaus reportedly said there was minimal market disruption and no broken trades resulted from the glitch.
