High-speed trading woes for Deutsche Bank?

• Already troubled by lawsuits and official investigations, Deutsche Bank (NYSE:DB) is facing another challenge - it's about to be sued in British court for using high-speed trading software.
• That lawsuit asserts the lender used a platform known as Autobahn to take advantage of millisecond changes in exchange rates to give clients worse prices than they were entitled to.
• Deutsche Bank has denied the claims, saying "we disagree with the allegations and will be defending ourselves in court."
