The Perpetuals Reference Rate is an index for perpetual contracts based on trade data from Deribit, Binance, and OKX. Inspired by the CME CF Bitcoin Reference Rate (BRRNY) methodology, it aggregates trades into 5-minute intervals, determining a volume-weighted median price for each. The final rate is derived from the average of 12 intervals. The daily model is calculated at 4:00 PM ET.

This is the Point-in-Time (PiT) variant of Perpetuals Reference Rate. PiT metrics are strictly append-only and their history is immutable. The historic data does not necessarily reflect the best current knowledge, but the information at the time when a data point was first computed. PiT metrics are ideal candidates for applications in model backtesting and related quantitative purposes. Read our article on PiT metrics for more information.
