To further improve the stability and fairness of index prices, Bitget will optimize the method used to calculate index price weights.
What is changing
Currently, each exchange's weight in the index price is based on its share of the total trading volume across all exchanges over the past 24 hours, with weights updated every four hours. Following the adjustment, the original dynamic weights based on trading volume shares will be replaced with fixed exchange weight coefficients.
Exchange weight = Exchange weight coefficient ÷ Sum of the weight coefficients of all active exchanges
Note: An exchange's weight coefficient may vary by trading pair and will be determined by Bitget based on market conditions.
Following the adjustment, the index price calculation formula will remain unchanged:
Index price = (Exchange A spot price × Exchange A weight) + (Exchange B spot price × Exchange B weight) +... + (Exchange X spot price × Exchange X weight)
Adjustment details
-
This adjustment will be rolled out starting October 26, 2026, and is expected to be fully completed by November 6, 2026;
-
This adjustment only affects how index price weights are calculated. All other index price calculation logic, including outlier exclusion and update frequency, will remain unchanged;
-
Following the adjustment, Bitget will centrally maintain the specific weight coefficients for each exchange. Users can view the latest index constituents and weights on this page: Index price | Bitget unified trading account;
-
This adjustment optimizes the underlying calculation logic. No action is required from users.
