Futures contracts expire, so a trader who wants to keep a position must close the expiring contract and open the next one: the roll. For Corn (ZC) the current front contract is ZCZ26, with a last trading day of 14 Dec 2026 and a first notice day of 30 Nov 2026. The next contract is ZCH27.
The exchange rule we apply for ZC: Last trade: business day before the 15th calendar day of the contract month. First notice: last business day of the month before. ZC is physically delivered: holding a position into the delivery period can create an obligation to make or take delivery, which is why speculative traders normally close or roll before the first notice day or last trading day.
The suggested roll date of 25 Nov 2026 is a convention, not an exchange rule. It is set a little before the first notice or last trading day, because liquidity moves to the next contract and many brokers require positions to be closed or rolled before then. Dates are calculated from the exchange's rules and its holiday calendar. The exchange calendar is the authority.
Roll convention: Suggested roll: 2 business days before the earlier of first notice day and last trade. A convention, not an exchange rule; brokers may require earlier exit. Exchange calendar: https://www.cmegroup.com/markets/agriculture/grains/corn.calendar.html
