|symbols||a single symbol or list of comma-delimited symbols (required)|
For option symbols, the symbology needs to follow that of the OCC. This format is up to 21 characters that represents the contract specifications of a particular option. The following components are used in constructing the symbol:
Notice the strike price is represented in 8 digits no matter what the number of digits of the actual strike price. The strike price is carried to 3 decimal places, but no decimal is used within the symbol. For example, the $200 strike for the IBM option above is represented as "00200000". Also, note the two "0's padded on the front to complete the 8-digit total.
