Index Calculation Rules
1、USDT margin contract uses the corresponding underlying USDT index.
USDT margin contracts use the corresponding underlying USDT index. To ensure that the spot index price reasonably reflects the fair spot market price of each currency, we will select currency pairs from more than 5 mainstream exchanges for each contract currency as the index weight component, and design exception handling logic to ensure a single transaction When the price deviates significantly, the index fluctuates within the normal range.
2、Calculation logic of spot index price:
a、Real-time access to the latest transaction price and volume of all index component exchange coin pairs of the currency.
b、Exchanges that have not been updated during system maintenance or the latest transaction price and volume within a period of time (each currency will be configured with a different time threshold) are invalidated and will not participate in the calculation this time.
c、The currency pair whose denomination currency is BTC is multiplied by the SuperEx BTC/USDT index and converted into USDT price.
d、Judging the current remaining valid exchange data:
3 or more platforms, effective exchange data by equal importance.
2 platforms, effective exchange data by equal importance.
1 platform, directly take the price of the remaining effective exchange as the index price;
