Deribit Options Data
The dataset contains all bitcoin (BTC) options trades on Deribit from November 29, 2016 to October 5, 2020. I downloaded the data from Deribit's API and specifically used it in my paper Forecasting bitcoin volatility: Evidence from the options market. Please see table below for the definitions of variables.
Unfortunately, Deribit recently changed the way its API responses to public queries so the data cannot be freely updated any more.
