Dark Pools is the pacy, revealing, and profoundly chilling tale of how global markets have been hijacked by trading robots - many so self-directed that humans can't predict what they'll do next. It's the story of the blisteringly intelligent computer programmers behind the rise of these 'bots'. And it's a timely warning that as artificial intelligence gradually takes over, we could be on the verge of global meltdown. "Scott Patterson has the ability to see things you and I don't notice. " (Nassim Nicholas Taleb, New York Times bestselling author of Antifragile, Fooled by Randomness and The Black Swan).
