In order to filter out already expired options, I was reading the iqfeed guide to options symbols:
https://iqfeed.net/symbolguide/index.cfm?symbolguide=guide&displayaction=support§ion=guide&web=iqfeed&guide=options&web=IQFeed&type=stock From what I understand, the letters before the first digits in the symbols represent the underlying. Then comes the info on the expiration data, with the first two digits representing the year, then 2 digits for the day and a letter for the month code. Then there are digits represnting the strike. So a code like CSCO1220V19 means Cisco October Put at 19.00 Expiring on 10/20/12 But why other symbols, like A11720A27.5, representing Agilent Call 20 expiring on Jan 20 2017 have an extra digit ('1') after the 'A' symbol? It doesn't make any sense. |

The additional 1 in the symbol is to designate it as a non-standard option, due to some sort of corporate Action.

Thanks for your answer.
How do you know when parsing the string, that it is not the first digit of the year? |

You may try parsing the symbol from the back instead of the front this may resolve your issue.
