1. The futures index price is the weighted average value of the underlying asset on major spot exchanges. It reflects the actual market value of the futures and continuously updates with changes in the spot price of the underlying asset.

2. The setting of the index price aims to reduce the risk caused by price fluctuations and market manipulation, providing a more stable reference price. Unlike the last price of an asset, KCEX selects the spot prices of the underlying asset on major exchanges as the source for futures index prices for all futures.

3. If a particular exchange's market data is consistently slow in updating or deviates significantly from other sources, its spot price data will be excluded from the calculation. If the quality of data from the excluded exchange improves, it will be reconsidered for inclusion in the calculation.

4. If the spot price of a particular exchange deviates from the median of all exchanges by more than ±3%, KCEX will activate a price protection mechanism and exclude the spot price of that exchange directly. (In extreme market conditions, the platform may adjust the median deviation coefficient for certain trading pairs or not be bound by this arrangement.)

Calculation Formula

Index Price = Sum of (Weight Percent of Exchange A * Spot Price of the Underlying Asset on Exchange A + Weight Percent of Exchange B * Spot Price of the Underlying Asset on Exchange B + ... + Weight Percent of Exchange N * Spot Price of the Underlying Asset on Exchange N)

Where:

Weight Percent of Exchange i = Weight of Exchange i / Total Weight

Total Weight = Sum of (Weight of Exchange A + Weight of Exchange B + ... + Weight of Exchange N)

Please note that KCEX will periodically update the index constituents and weights. In the event of extreme market conditions or significant price deviations, KCEX may take additional protective measures, including but not limited to changing index constituents and weights without prior notice.
