Options on Commodity Futures Calendar Spreads These products are options on the price differential between two contract months, rather than on the underlying asset itself. Therefore, they offer alternative hedging capabilities compared to standard options, and can provide a more precise hedge against adverse movements in price spreads in the grain and oilseed markets. Calendar spread options are sensitive only to the value and volatility of the spread itself, rather than the price of the underlying commodity. They are more efficient than combining options on 2 different months in an effort to replicate the spread, and provide a better risk management device for hedgers and market participants exposed to calendar spread risks. Options on Commodity Futures Calendar Spreads
These options will be listed with the futures calendar spread as the indicated underlying. In line with the current listing of Eurodollar calendar spread options, there will not be a synthetic future listed. These options will support zero and negative strike prices.

Events & Announcements |
The file will contain CME Globex production instrument data and daily settlement prices. It is provided as a convenience to users who have specific or unique Security Definition processing requirements. This file is static and will be refreshed at the end of each trading day. It is not your primary source for instrument information. Best practices require that CME Globex users obtain all Security Definition information from the Incremental Data channel or the Instrument Definition loop channel to ensure that intra-day instrument additions are captured. Once a trading day has started, the following intra-day changes are not reflected in the FIX/FAST Security Definition file:
CME Group strongly recommends the FIX/FAST Security Definition file only be used in addition to, or as a backup for, standard Security Definition message processing. More information on the CME Group FTP site and the Security Definition Information file is available in the CME Globex Holiday Trading Hours Update
