Index Price Computation. 1. The latest price and volume of each index constituent is retrieved from selected exchanges in real time. 2. If the relevant exchange is under maintenance, or if any constituent price/volume has no update for a certain time , the constituent data will be temporarily treated as invalid and excluded from index calculation. 3. If the exchange trading pair in the index sample is inconsistent with that of the index, it shall be converted into the corresponding price of the same currency based on BTC/USDT, BTC/USD, USDC/USD, USDT/USD, etc. For example, if a component of the ETH/USD index is ETH/USDT, multiply the component by the price of the USDT/USD index to convert it into the price of the ETH/USD index. 4. Final calculation depends on the number of exchanges with valid data. More details: More than 3 exchanges with valid data: apply equally-weighted price average ..Only 2 exchanges with valid data: apply equally-weighted price average..Only 1 exchange with valid data: its last traded price will be used as the index price directly..
