Is a position of five E-mini futures contracts financially equivalent to a position of one regular-sized larger futures contract on the same side of the market in the same contract month?
Yes. The daily settlement prices for the E-mini futures contracts are the same as the settlement prices for the corresponding contracts months of the regular-size contracts. Accordingly, a customer who has a long position of five E-mini futures contracts and a short position of one regular-sized futures contract in the same contract month is perfectly hedged. CME Group will impose no initial margin (performance bond) requirements on such a hedged position.

May a customer liquidate E-mini futures positions against offsetting positions in the regular-sized futures contract without making additional trades in the market?
Yes. With the customer's consent, a clearing member may offset and liquidate E-mini futures positions against offsetting regular-sized futures positions held in the same account in a 5:1 ratio of E-mini to regular-sized futures contracts. The positions shall be offset at the previous day's settlement price. The clearing member shall notify CME Clearing of offsetting positions by submitting reports to the clearing house through a special online entry screen designed for that purpose
