Every options contract has a unique symbol that identifies it. This symbol is made up of several different pieces of information, including the underlying asset, the expiration date, the strike price, and the type of option. For example, let's say you're looking at the options contract for ABC Company with an expiration date of June 1 and a strike price of $50. The 'ABC' part of the symbol tells you the underlying asset, in this case, ABC Company stock. The '06' tells you the month of expiration, in this case, June. And finally, the '50' tells you the strike price. There are also two different types of options - calls and puts - which are indicated by either a 'C' or a 'P' at the end of the symbol. Thus, a call option for ABC Company with an expiration date of June 1 and a strike price of $50 would have the symbol 'ABC10061C50'.
