Deribit BTC Index
Currently the Deribit BTC index is made up the latest prices from Bitstamp, Okcoin, Bitfinex, Itbit, Coinbase and Kraken. From those 6 exchanges Deribit retrieves continuously best bid and best ask prices and calculates the mid price. Then the highest and lowest price are taken out. The remaining 4 exchanges are then each for 25% accountable for the BTC price index. So at all times there are a maximum of 4 exchanges making up the BTC price index weighting each 25%.
There is a page dedicated to the price index where you can see at any time which exchanges are actually part of the index at this very moment. (https://www.deribit.com/main#/prinx_chart)
If we don’t receive any signal from an exchange for more than 3 minutes, this exchange will be taken out of the index calculation. If deribit can only receive real time data from 1 or 2 exchanges, these will make the index, though, if ever, this would occur very rarely.
