High-Frequency Trading Happy Hour, featured in The Wall Street Journal, has congregated high-frequency (and some low-frequency too) traders, quants, managers, investors and key decision makers for evenings of networking and cocktail for the last 15 months, starting in New York, and continuing in Mumbai, Hong Kong, and Singapore. As reported by Securities Technology Monitor, Chicago's Financial District is a hotbed of high-speed trading; the founders of Getco used to work in Chicago's futures and options pits. And, guess which set of markets functioned properly all day long on May 6, reported no erroneous activity and busted no trades? CME Group, parent of the Chicago Mercantile Exchange, the New York Mercantile Exchange, the Board of Trade of the City of Chicago and the Commodity Exchange, known as Comex.
