Equity Calendar Spreads on CME Globex  
As previously announced, the trading convention for equity futures calendar spreads on the CME Globex platform will match the current equity convention, and is the opposite of the e-cbot convention. On CME Globex, the trading convention is that a bid equals sell leg 1 (near month) and buy leg 2 (deferred month), resulting in a positive spread price. The legacy e-cbot convention is that a bid equals buy leg 1 (near month) and sell leg 2 (deferred month), resulting in a negative spread price.
