Another stock exchange wants to slow down trading, saying some rapid-fire firms have found a way to exploit slower orders, scaring investors away from its market.
The Chicago Stock Exchange has proposed to implement a speed bump, mimicking an earlier move by IEX, the upstart stock exchange made famous by Michael Lewis in the book "Flash Boys". In June, IEX won approval to impose a speed bump of 350 microseconds, or millionths of a second, a delay that it said is just long enough to protect investors from predatory high-speed trading that can front-run the orders of slower investors.
