Fellow Binancians,
Binance constantly reviews its product and service offerings to ensure the best user experience for all users. Effective from 2025-05-05 09:00 (UTC), Binance Futures will make adjustments to mark price calculations by updating the basis of Price 2 from 2.5-minute basis to 1-minute basis, with details as follows:
Futures Contracts
Before the Adjustment
After the Adjustment
USDⓈ-M and COIN-M Perpetual Contracts
Mark Price = Median (Price 1, Price 2, Contract Price) Where Price 2 = Price Index + Moving Average (2.5-Minute Basis)
Note: The Moving Average (2.5-Minute Basis) is calculated as the average of 30 data points over a 2.5-minute period.
The basis is calculated every 5 seconds by taking the average of the bid and ask prices and then subtracting the Price Index.
Mark Price = Median (Price 1, Price 2, Contract Price) Where Price 2 = Price Index + Moving Average (1-Minute Basis)
Note: The Moving Average (1-Minute Basis) is calculated as the average of 60 data points over a 1-minute period.
The basis is calculated every second by taking the average of the bid and ask prices and then subtracting the Price Index.
USDⓈ-M and COIN-M Delivery Contracts
Mark Price = Price Index + Moving Average (2.5-Minute Basis)
Note: Moving Average (2.5-Minute Basis) = Moving Average ((Bid1 + Ask1) / 2 - Price Index), calculated each second in a 2.5-minute interval.
The basis is calculated every 5 seconds by taking the average of the bid and ask prices and then subtracting the Price Index.
Mark Price = Price Index + Moving Average (1-Minute Basis)
Note: Moving Average (1-Minute Basis) = Moving Average ((Bid1 + Ask1) / 2 - Price Index), calculated each second in a 1-minute interval.
The basis is calculated every second by taking the average of the bid and ask prices and then subtracting the Price Index.
