There are many stock options contract missing in the expired instrument section, first I got the list the of available expired and available options contract of a stock, but when I tried to fetch the data of those options contracts, many options contract json file came empty, and especially for the expiries like 2025-03-27 and 2024-12-26, not a single stock options contract’s data was fetched, all json returned empty, and then I tested this pattern with top 25 nifty stock options , but all stock’s options data was not available for these expiries, and those expiries whose data is available in those expiries too, there were 5-10 contracts missing here and there
why is this happening how to fix this?
please fix this
