&gt; and the original &quot;flash boys&quot; book make a compelling case<p>Except it didn&#x27;t, it merely showed that the author has no understand of what HFT is.  Flash boys is full of hyperbolic bullshit that may sell books but shows no real understanding of how the market works. He misuses the term front running (which is illegally using knowledge of your clients positions to trade ahead of them) and applies it to being a faster speculator, which is in no way front running.  The guy quite simply doesn&#x27;t know what he&#x27;s talking about.
