CME profit falls as trading volume declines

``CME--the world's biggest futures exchange operator in terms of contracts traded--posted a 12% decrease in trading volume to an average of 12.6 million contracts a day. Interest rate volume, meanwhile, fell 2.3% to a daily average of 6.7 million contracts. "Historically low levels of volatility impacted the overall market during the second quarter, although the effect on CME was lessened by the diversity of our product lines," CME Group Executive Chairman and President Terry Duffy said in a news release.''
