Are there any new methods on pulling expired options data?

Not initially. However, I attempted to modify the underlying script shown in your article to make it compatible with options queries, but found that the underlying procedure fails. Unlike expired futures RIC codes, which are accessible from a standard search Definition query, the expired options RIC codes are not.

Using the library written by one of your devs above, you can confirm this. Compare the results of

browser.execute("AAPL",
                filter = """RCSAssetCategoryLeaf eq 'Equity Cash Option' and
                         ExpiryDate ge 2025-01-01 and 
                         ExpiryDate le 2026-01-01""")

against

browser.execute("AAPL",
                filter = """RCSAssetCategoryLeaf eq 'Equity Cash Option' and
                         ExpiryDate ge 2024-01-01 and 
                         ExpiryDate le 2025-01-01""")

You will observe that the former procures results while the latter does not. Keep in mind that the library I reference uses similar underlying filter syntax, which you can observe in the _build_filter_criteria method from the FuturesRICs class shown in your attached article.

What are your thoughts?

Exactly, they are not in the search database. However, if you run

ld.get_history("NDXa172091900.U^A20")

there is information. So they are in your pricing database, but typical search functions do not apply. In my original question, I just wanted to know if any new efforts have been put towards more efficiently finding this sort of expired information. I wonder if there is some sort of underlying key that you keep under the hood which tracks these expired RIC codes.

Thank you, that will be greatly appreciated.

Thank you for the news on your expired futures function; that will come in useful for me later. Regarding the article you sent me, it can certainly be expanded to explore a larger range of possible strike prices like the original article. Nevertheless, within what period of time do you anticipate rolling out the new feature for accessing this expired options data?
