Is this correct? My interpretation of the symbol is it's: base symbol=AAPL expiry=2012-01-21, right=call, strike=120.0 More generally, what date does your options coverage (daily granularity) start from? Thanks Andrew

DTN_Stephen -DTN Guru- Posts: 453 Joined: Aug 22, 2014	Posted: Mar 1, 2021 07:48 AM Msg. 3 of 5 The symbol you have listed is an expired option If I am understanding you correctly YES you are receiving data on an expired option. Your interpretation of the symbol is correct. However we do not understand your comment about some 13 years before expiry date since the option is from 2012 and the current year is 2021. Please be aware historical option data prior to 2012 is sporadic. Stephen Shockey Senior Customer Support Representative and Product Support Specialist DTN 800-779-7299 support@iqfeed.net

There was a symbol conversation in 2010; in addition in the past these symbols were recycled. Data going back to 1999 will no longer be available since it is not valid.
