Special Considerations
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:
- (1) - Underlying symbol
- (2) – 2-digit expiration year
- (3) – 2-digit expiration month
- (4) – 2-digit expiration day
- (5) – "C" for Call or "P" for Put
- (6) – 8-digit strike price
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.
