@raja1sttarde The exchange re-uses the tokens once expired so you can't store tokens for expired instruments. We will recommend you to fetch instrument list daily or after every expiry date, check instrument file here.
@rakeshr thanks for your reply. I knew the instrument tokens are valid only for the life of the options, ~3month. here it was reassigned within its life cycle. now am i to understand that instrument token is valid only for a day and it can be re-assigned any time, even within its life cycle?
