The contract expiration is always the two front months followed by two quarterly months (sometimes one of the two front months is also a quarterly month totaling three quarterly months) for a total of four expirations per product class for most OneChicago single stock and ETF futures. Those products will generally follow the quarterly cycle of March (H), June (M), September (U) and December (Z). The expiries for the longest term contracts range from six to eight months, depending on the time of the year. Certain exceptions may apply — see OneChicago’s SSF Listings for details.
The last day of trading and expiration date for single stock futures and ETF futures will typically be on the third Friday of the month. In the event that the third Friday of the month is not a business day, the last day of trading will be on the business day immediately prior to the third Friday of the month (i.e. Thursday).
The last day of trading for narrow-based indexes, including OneChicago Select Indexes, will typically be on the third Thursday of the expiration month, before expiration/final settlement day, which typically is the third Friday of the expiration month. If the Exchange is not open for trading on that third Friday, expiration/final settlement will be the preceding business day and the final trading day will be the day prior to that.
