Got some time to kill this weekend. I've been working in HFT for the last 7 years. Futures, FX, some equities, mainly market-making. I've always been curious about supposed front-running allegations and other myths that are assumed/spread by people outside the industry. So... I'm not here to debate subjective opinions about HFT. What I'm willing to do is answer any concrete questions about the industry that I can (and admit when I can't), within reason of confidentiality and competitive advantage of course. Maybe I'm opening up a can of worms, or maybe no one cares to even respond/ask. We'll see.
