Dear Sirs: Concerning CBOE proposed rule change, it is a violation of CBOT members rights to use CBOE markets. This is a case of the CBOE thinking they can take away something from CBOT members who have used their time and money to found the CBOE. To think they can just walk away from the CBOT just by changing a rule is ridiculous. Thank you for your consideration in this matter.
