Former high-frequency trader Dave Lauer is set to attack the practice at a hearing of the Senate Banking subcommittee today. Lauer will testify that HFT has allowed some firms to trade profitably at the expense of other investors, and that it has put markets at risk of crashing. "We are truly in a crisis," Lauer will say. High-speed trader Chris Concannon will give the other side of the story.
