TD Ameritrade Says Thinkorswim Integration Causing ‘Issues’

TD Ameritrade Holding Corp. (AMTD) said some of its clients are experiencing issues with electronic trades after the company integrated its Thinkorswim options broker this past weekend.

“In general the integration has gone well, with all clients able to place trades on our platforms,” Kim Hillyer, a spokeswoman for TD Ameritrade, wrote in an e-mail to Bloomberg News. “However, we are experiencing some issues, impacting a subset of clients and their ability to place trades electronically.”

Hillyer said she couldn’t give further details about the issues. She said Omaha, Nebraska-based TD Ameritrade identified the problem and is “actively working to resolve it.”

The online broker brought more than 250,000 Thinkorswim accounts to the TD Ameritrade platform in the final integration last weekend, according to Hillyer. TD Ameritrade bought options brokerage Thinkorswim Group Inc. for $749 million in 2009 to expand beyond equities.
