I am a third generation member, and a second generation former Director of the Chicago Board of Trade. My expertise is in Cash Grain Marketing and Grain Hedging. Your expertise is the regulating of Securities and Security Exchanges. Have you now become the experts in Contract Law? This contract dispute belongs in the courts.

Matter of fact it IS in the Courts.

I believe that the CBOT has a valid contract with the CBOE. You may or not believe this contract is valid.
Please let the experts decide
