Whoa, A Glitch In The HFT

From the creator of Citadel's HFT desk for options: "You have multiple HFT trading firms and sometimes their agendas are complementary and sometimes they’re not. There could be a time where these HFT programs unintentionally collaborate and you have a two- or three-minute period where the markets are going crazy. Then other traders respond to it and it simply gets out of control."
