Expiration Dates

Two quarterly expirations and two serial months of OneChicago's security futures products will trade at all times, for a total of four expirations per product class. OneChicago's products will follow the quarterly cycle of March (H), June (M), September (U), and December (Z). The serial months traded will be the two nearest months that are not quarterly expirations.

The last day of trading and expiration date for a given contract 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).
