get https://api.amberdata.com/markets/derivatives/analytics/volatility/open-interest/tradfi
This endpoint returns the end-of-day (EOD) open interest snapshot. Unlike the crypto landscape where open interest is continuously updated, the tradFi environment only updates open interest once per day. This is because the clearing house needs to tally up all the activity for the day, in order to publish outstanding open interest at the end-of-the-day.
