NYSE Arca suffered a technical glitch Monday morning that forced a 15-minute trading halt on the largest U.S. trading venue for exchange-traded funds.
The all-electronic exchange, part of the New York Stock Exchange ICE, -0.05% is home to $2.2 trillion in exchange-traded products, 92% of U.S.-listed funds, according to its website.
The problem related to a software update that rolled out during the weekend, said Kristen Kaus, a NYSE spokeswoman.

A problem was first identified shortly before the market opened, and NYSE Arca sent a systems alert at 9:08 a.m. ET. Another alert at 10:27 a.m. said customers were receiving unsolicited trade cancellations. At 10:46 a.m., NYSE Arca sent an alert halting trading from 10:50 a.m. to 11:15 a.m.
