(Bloomberg) — TD Ameritrade Holding Corp.s Thinkorswim options brokerage experienced a technical malfunction Friday that snarled key aspects of the service.
Customers took to Twitter to complain that, among other problems, transactions didnt seem to be going through. TD Ameritrade acknowledged it was having trouble informing clients that trades were completed. Kim Hillyer, a spokeswoman for TD Ameritrade, said the companys Thinkorswim service malfunctioned and the incident was resolved at about 10 a.m. New York time.
This morning we experienced an issue with an order router supporting one of our trading platforms, Hillyer said in an e- mail. 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.
