ALBANY, N.Y. (AP) — An official familiar with the investigation says the New York Attorney General's Office has issued subpoenas to six firms and sent a letter to another for details about split-second stock trading and any unfair advantages.
The official tells The Associated Press the subpoenas went last week to trading firms including Chicago-based Jump Trading LLC and Chopper Trading LLC and Tower Research Capital in New York. The official spoke on condition of anonymity because he wasn't authorized to publicly discuss the subpoenas.
Attorney General Eric Schneiderman has said advantages in computer hardware and placement enable some traders to get millisecond timing advances on trades.
His office, with New York authority to investigate securities fraud, is seeking details about trading strategies and special arrangements with trading venues.
