To ensure the spot index price accurately reflects the spot market price of each token, we have carefully selected the market prices of 3 or more major exchanges as the weighted index constituents for each token. Measures are introduced to handle abnormal situations.
Spot Index Constituents
Index Update Rules:
If an exchange data source stops updating or is inactive for a long duration, we will temporarily remove it from index calculation until it starts updating data again.
The number of active exchanges (deduced from a):
(1) >=3 exchanges, weighted average index price of these active exchange prices ( If an exchange's price deviates by 3% or more from all exchanges' median, then this exchange's price will be the median * 1.03 or median * 0.97)
(2) =2 exchanges, average of prices
(3) =1 exchange, that exchange price.
For XXX/BTC trading pairs in the index components, it will be multiplied by the Mexo BTC index and calculated.
