What is an Index Price?
The Index Price is a weighted average of spot prices of a cryptocurrency from major exchanges. It updates every 5 seconds to reflect the fair value of the cryptocurrency.
CoinEx Index Price Calculation
CoinEx calculates the Index Price using weighted prices from various major cryptocurrency exchanges and employs an exception handling mechanism to keep the Index Price within an acceptable range during drastic fluctuations on any exchange.
The main reference exchanges include Binance, OKX, Bybit, KuCoin, and Gate.io.
For example, if the index price for a cryptocurrency is derived from exchanges A, B, C, and D, and exchange A stops sending trading data for over 15 minutes, CoinEx will automatically activate a protection mechanism. This removes exchange A from the calculation and evenly redistributes the weights of the remaining three exchanges until A resumes operations. If exchange B also encounters this issue, CoinEx will similarly remove B and redistribute the weights between exchanges C and D.
