The COMEX has both futures and options trading.
The symbol template for futures is Smy where S is the symbol, m is the month code, and y is the last digit of the year.
The symbol template for options on futures is -Smsss where S is the symbol, m is the month code, and sss is a three-digit strike price.
There are also "Weekly Options" which use the template -Swsss where S is the symbol, w is the weekday code, and sss is a three-digit strike price.
Note: Options on futures require a "negative sign" or "dash" (-) before the symbol.
Spot prices for Gold and Silver are also available from Handy/Harmon. You must enter the symbol in Exchange:Symbol format, such as:
