Computer-trading worries grow as NYSE builds new datacenter

With all of the scrutiny that high-frequency trading is now under in the media and in Congress, the New York Stock Exchange is probably none too thrilled that the Wall Street Journal has uncovered fresh details of NYSE’s giant new datacenter, which the exchange is building in a former New Jersey quarry. The new datacenter will significantly advance the amount of computer-automated trading that already dominates global markets, housing as it will “several football fields of cutting-edge computing equipment for hedge funds and other firms that engage in high-frequency trading,” according to the WSJ. So if you were recently shocked to learn that an estimated 70 percent of stock trading is just computers trading against one another, get ready for that number to go even higher.
