There are all manner of odd themes in the book. That Brad Katsuyama got paid exorbitant amounts of money to execute trades poorly for large institutions is presented as a virtue, even though his bonus came specifically from those large institutions profits we are so outraged that HFT is trading against.

My favourite one is a section where Lewis starts naming HFT algos and they invariably have names like Dagger, Viper, etc. yet he never seems to point out the HFT Brad Katsuyama created was named Thor.
