A US federal court in Chicago dismissed a lawsuit previously brought by a purported class of public investors who claimed that, beginning in 2005, the Chicago Board of Trade and the Chicago Mercantile Exchange disadvantaged their trading by allowing certain high-frequency traders “to profit from peeking at everyone else’s orders and price data and to act on this price and order information.” The court dismissed the lawsuit claiming that, in many cases, there was no private right of action for allegations made by plaintiffs, or they did not plead their cause of action with sufficient detail.

In August 2015, a federal court in New York City dismissed five lawsuits against multiple stock exchanges, Barclays PLC and Barclays Capital Inc., that all echoed claims made in Michael Lewis’s 2014 book Flash Boys: A Wall Street Revolt that high-frequency traders have gained an unfair advantage trading stocks.
