The snowstorm hit Chicago, too, but failed to slow trading in the commodities pits, which at one point this week hit an all-time high.
According to CBOT, daily volume exceeded 7 million contracts on Tuesday, surpassing the previous record established last summer. The trades were conducted via the traditional open outcry system, but CBOT officials noted the exchange also recorded a new daily volume record of more than 6 million contracts on the electronically traded "e-CBOT' system.
New open interest records also were tallied for several financial instruments, and a record 407,000 soybean contracts were active when the market closed on Monday. Open interest represents the number of trading positions that have not been offset and closed by the end of a trading day.
