TD Ameritrade Holding, parent of the biggest discount brokerage firm by trade executions, said it has resolved "widespread" problems experienced when trying to execute orders, including those that it has accepted, company officials said on Friday morning.
Via email, TD Ameritrade wrote, "This morning we experienced an issue with an order router supporting one of our trading platforms. The issue was related to a software update that we made overnight. Client orders were routing to the street, but we experienced slowness in our messaging from the street and back to clients. The issue was resolved at approximately 10 a.m. ET. "
The company is not yet aware of the cause of the problem, said Chris Gulick, who works in the Omaha, Nebraska-based company's office of the president.
"We are having some order issues and are working to resolve," trading product head Nicole Sherrod wrote earlier on Twitter. "I know this is a critical day and all hands are on deck."
TD Ameritrade also responded to its customer complaints via its Twitter account.
The company's stock was up about 0.6 percent in mid-morning trading but had traded higher earlier.
Gulick said the issue appears to be affecting orders designated for a variety of marketplaces. Asked if all orders received this morning or waiting to be executed are affected, he said the problem is "widespread" and began around the time of the market opening at 9:30 am ET.
The issues come two days after the New York Stock Exchange had to halt trading for more than four hours after experiencing what it said was a glitch during a routine software update. Also, the Wall Street Journal site went down for about an hour, and United Airlines had to ground its planes due to a computer problem.
