Electronic trading across CME Group Inc.'s futures markets resumed late Tuesday after technical problems triggered an hourslong trading halt.

The problem started at 7:39 p.m. Eastern time and trading across all markets on CME's electronic platform was halted about 28 minutes later, according to a CME spokeswoman.

The Chicago-based company is the world's largest exchange operator by market capitalization, offering futures and options contracts for an array of assets, including soybeans, wheat, crude oil and U.S. stocks. Trading on Nymex, Comex and the CBOT were also affected by the glitch.

There were no live quotes for e-mini S&P 500 futures for three hours starting at around 7:40 p.m. Eastern time, according to FactSet. These are the most liquid contracts available for U.S. stocks and are traded virtually around the clock.

CME said all its electronic markets reopened by 10:45 p.m. Eastern time and added that all "day and session orders" with Tuesday's date would be canceled.

The outage is unusual for CME, whose technology is typically reliable, said Nick LaMaina, senior vice president at TradeStation, a Florida-based brokerage that allows individual investors to access CME's markets. On Tuesday evening, TradeStation used a rarely invoked contingency plan to ensure that customers' orders were properly handled despite the outage, Mr. LaMaina added.
