Astral Index Price is a type of index price formed based on a weighted average strategy. It aims to avoid extreme market conditions caused by individual exchange price deviations and reduce the possibility of generating a large number of liquidation orders or facing liquidation risks for the platform. By assigning weights to prices from different exchanges based on their trading volumes, exchanges with higher trading volumes have a greater impact on the index price.
The specific weighted average strategy is as follows:
-
For each exchange, obtain the crypto price and corresponding trading volume of the data pair (e.g., BTC/USDT).
-
Quantify and assign weights to different exchanges based on factors such as liquidity, trading volume, and robustness of constituent exchanges. Exchanges with higher trading volumes have higher weights.
-
Calculate the weighted average of prices from all exchanges by multiplying each exchange's price with its corresponding weight.
-
The Astral weighted average index price is the result of the weighted average price.
