"Thanks for following up with me. You guys do a great job in tech support." - Comment from Phelps

"If you are serious about your trading I would not rely on IB data for serious daytrading. Took me a while to justify the cost of IQ Feed and in the end, it's just a 2 point stop on ES. Better safe than sorry" - Comment from Public Forum

"I've been using IQFeed 4 in a multi-threaded situation for the last week or two on 2600 symbols or so with 100 simultaneous daily charts, and I have had 100% responsiveness." - Comment from Scott

"Just a quick one to say I'm very impressed so far :) The documentation for developers is excellent and I've quickly managed to get an app written to do historical downloads. The system is very robust and pretty quick considering the extent of data that's available. The support guys have been very helpful too, in combination with the forums it's been plain sailing so far!" - Comment from Adam

Author	Topic: Expired Equity/Index Options (9 messages, Page 1 of 1)

However, we don't provide any sort of symbol lookup for you to determine what the valid strike prices were at any point in history. Also, you would only be able to feasibly build the symbols that have existed since the OSI changed symbology a while back.

We won't have tick data available for anything that expired more than 120 days ago (since we limit tick data to the most recent 120 days).
jcrivello -Interested User- Posts: 12 Joined: Sep 7, 2011	Posted: Sep 22, 2011 11:40 AM Msg. 6 of 9 Do you have any suggestions on how I might lookup or generate a list of expired option contracts for an underlying then? I also tried using the SBF/Symbols By Filter command to lookup the symbols, but it looks like that API (also) only returns non-expired contracts. I could take a guess at the expiration date based on the OCC options expiration calendar, but then I would have to permute through ALL the likely strike prices to find the valid symbols. This isn't a great option because it would be slow, and I imagine your operations staff wouldn't appreciate my executing a bruteforce search for symbols in this manner. Sounds like Telvent stores a ton of useful expired minute/daily data and even recently expired tick data, but it is looking almost impossible to access it without being able to look up the symbols first!
