Instrument lookup by id for expired instruments.

prp edited January 2021 in General
How do I find the symbol, strike price, expiry date, option type of expired contracts based on their instrument ID?

If it helps, I have the timestamp of time when the quotes were obtained.

    The instrument token is unique only for the current day. It can be reused by the exchange once an instrument expires. It is recommended to store a combination of exchange and tradingsymbol as the key.

    You can get to know strike, option type from the tradingsymbol but you may have to store expiry date seperately.
