Deribit acquires via API the latest bid- and ask prices from above mentioned exchanges every 6 seconds.
What if Deribit is not able to receive data via API from an exchange?
In the case that Deribit fails to obtain data from an exchange (perhaps due to suspended trading, market interruptions and DDoS attacks), the price used shall be the last effective price obtained. In the event that Deribit does not obtain any data for longer than 1 minute, the price from the relevant exchange exchange is considered to have no significance, and will have no weight in the deribit price index. As soon as data connection is recovered, the exchange will again be part of the index.
It is also possible that an exchange is to be (temporary) removed from the index. This can happen if the price on the exchange doesn't reflect the market value of bitcoin. This could happen when funds cannot be withdrawn from the relevant exchange, or if there are bankruptcy rumours. If an exchange is to be removed from the index, this will happen only after prior announcement by Deribit.
The final objective is that the deribit index reflects the most accurate price of bitcoin in any moment in the market.
