The symbology for a stock option symbol is the symbol root followed by a space, the expiration date, option type, and strike price.
[Option Root]<space>[YYMMDD Expiration Date][C or P][Strike Price]
For example, the symbol for a MSFT January 2011 27.5 Call is “MSFT 110122C27.5"
In the Symbology expressions given in this section, [x] denotes a parameter that should be replaced with a value. The brackets ([ ]) are not a part of the expression. For example, [Symbol root] should be replaced with a symbol, such as ORCL. Items in italics are optional.
