Dark Pools is a page-turning, fascinating account of how computerized algorithmic high-frequency trading (HFT) and electronic platforms evolved, took over financial markets and turned the NYSE floor into a mere “puppet-show for TV.” Author Scott Patterson, a reporter for theWall Street Journal, is a consummate observer. Dark Pools is a follow-up to his New York Times bestselling, award-winning The Quants (2010). His account of what’s transforming capital markets cross-references Broken Markets by Sal Arnuk and Joseph Saluzzi, which I reviewed for Seeking Alpha.com June 30, 2012.
