CME CF Reference Rates are a daily reference rate of the U.S. dollar or Euro price of the associated cryptocurrency. The rates represent the aggregated, executed trade flow of the particular cryptocurrency pair on major spot exchanges. All relevant transactions during a specific one-hour calculation window are added to a joint list, recording the trade price and size for each transaction. This one-hour window is then partitioned into 12 five-minute intervals. For each partition, the volume-weighted median trade price is calculated from the trade prices and sizes of all relevant transactions (i.e., across all constituent exchanges). The reference rate is then given by the equally weighted average of the volume weighted medians of all partitions.

Details of the methodology can be found in the CME CF Cryptocurrency Reference Rates Methodology Guide.
