It was confirmed that a system failure occurred in U.S. stock transaction services at some securities firms last night.
According to the financial investment industry on the 9th, at night on the 8th, an order receipt error occurred in the mobile trading systems (MTS) of five securities firms—Meritz Securities, NH Investment & Securities, DAISHIN SECURITIES, Kakao Pay Securities, and Toss Securities.
This system failure is known to have been caused by a system failure at a local U.S. broker.
Toss Securities said in a notice, "From 10:30 p.m. to 10:47 p.m. on the 8th, some orders were not received properly," and added, "Fills for some unfilled orders, as well as modification and cancellation orders, are not being processed normally."
Meritz Securities also experienced a phenomenon in which orders were not received for 8 minutes starting at 10:40 p.m. Meritz Securities said, "All systems are now back to normal," and explained, "Transactions are proceeding smoothly." NH Investment & Securities also said, "Immediately after recognizing the error, we switched brokers to ensure there were no disruptions to new orders."
