• What is a price index?

A PRICE INDEX is a normalized average, typically a weighted average, of price relatives for  a  given class of goods or services in a given region, during a given interval of time.


  • How does CP Processor calculate the price index for popular cryptocurrencies?

The BITCOIN PRICE INDEX – iBTC is calculated based on the Relevant Transactions on all Representative Exchanges. Calculation steps for the iBTC on any given Calculation Day are as follows:


  1. All Relevant Transactions are added to a raw database, recording the trade price and size for each transaction.

Raw data consist of data in this form:

Date Time Type Price Amount ID Exchange
YYYY-MM-DD HH-MM-SS bid/ask string string string string

2. The data is partitioned into 6 equally-sized time intervals of 10 seconds each.

3. For each partition separately, the volume-weighted median trade price is calculated from the trade prices and sizes of all Relevant Transactions, i.e. across all Representative Exchanges. A volume-weighted median differs from a standard median in that a weighting factor, in this case trade size, is factored into the calculation.

4. The iBTC is then given by the equally-weighted average of the volume-weighted medians of all partitions.
