I read the book the week it came out and it felt like watching a gripping thriller. I think the reaction/ debate to his book was a (welcomed) distraction for the Wall Street bankers. His book left much unanswered, inevitably, but I fail to see any progress/ change since he published it. His debate on Bloomberg with William O'Brien (BATS Global Markets Presidents) was legendary and great viewing. But ultimately Brad Katsuyama came out as the hero of the book and it would be interesting to know how the IEX Group are doing now... I hear there are plans to make it in to a movie? Perhaps I will be able to watch it as a gripping thriller...
