Dear Team,
In the Option Chain help api, currently we can just pass the expiry date for the Symbol in timestamp field. So we cannot go to a specific timestamp to fetch the option chain. The only option is to store the live feed of data coming from Option Chain api locally and calculate the required timeframe say 1min or 3min or 5min or ....... But my question is what is the frequency of data update in this api? The "oich" has a value being populated, what is the basis for this calculation?
Thank you.
