I just opened an account with Interactive Brokers. The 2/11/11 closing price for May 2011 Corn on the CBOT was 717 2/8. IB has it quoted at 7.0875 close. Am I missing something?
Yes, I am sure about the May vs March contract. In fact, CSI data's closing price for May 2011 corn agrees with the CBOT quote. Hence, my concern about Interactive Brokers price discrepancy.
