High-profile attorney Michael Lewis filed a class-action lawsuit against 13 stock exchanges over high-frequency trading. The lawyer is of no relation to author Michael Lewis, whose book "Flash Boys" explained high-frequency trading earlier this year.
The case, filed on behalf of Harold Lanier, is filed in U.S. District Court for the Southern District of New York. It charges, among other things, that the exchanges discriminated against some investors by selling "advance access" to market data using private feeds and co-location services.
New York Stock Exchange, BATS Exchange, Nasdaq OMX and Chicago Board Options Exchange declined to comment.
The Guardian first reported the news Friday afternoon.
