(The above data and indicators may be adjusted in real time based on market conditions without prior notice.)
1. Assume for BTCUSDT perpetual futures, the non-basis price limit range is ±4%, the hard price limit range is ±6%, and the basis price limit range is ±2%.
Within 10 minutes of the BTCUSDT perpetual futures launch (non-basis price limits):
Highest bid price = min [Spot index * (1 + 6%), Spot index * (1 + 4%)]
Lowest ask price = max [Spot index * (1 - 6%), Spot index * (1 - 4%)]
10 minutes after the BTCUSDT perpetual futures launch (basis price limits):
Highest bid price = min [(Basis average of the past 10 minutes + Spot index) * (1 + 2%), Spot index * (1 + 6%)]
Lowest ask price = max [(Basis average of the past 10 minutes + Spot index) * (1 - 2%) , Spot index * (1 - 6%)]
2. Assume for BTCUSDT quarterly futures, the non-basis price limit range is ±4%, the hard price limit range is ±15%, and the basis price limit range is ±3%.
Within 10 minutes of the BTCUSDT quarterly futures launch (non-basis price limits):
Highest bid price = min [Spot index * (1 + 15%), Spot index * (1 + 4%)]
Lowest ask price = max [Spot index * (1 - 15%), Spot index * (1 - 4%)]
10 minutes after the BTCUSDT quarterly futures launch (basis price limits):
Highest bid price = min [(Basis average of the past 10 minutes + Spot index) * (1 + 3%), Spot index * (1 + 15%)]
Lowest ask price = max [(Basis average of the past 10 minutes + Spot index) * (1 - 3%) , Spot index * (1 - 15%)]
The above price limit rules apply to both opening and closing positions. If users open long or close short, a hard price limit will be triggered when the order price is higher than the highest bid price; if users open short or close long, a hard price limit will be triggered when the order price is lower than the lowest ask price.
Price Limits Before the Delivery
For USDT-margined weekly futures contracts, there is a special price limit of ±1% in the 10 minutes before settlement.
If the BTCUSDT weekly futures contract has a hard limit of ±6%, then in the final 10 minutes before delivery,
the specific price limits are:
Highest bid price = min [Spot index * (1 + 1%), Spot index * (1 + 6%)]
Lowest ask price = max [Spot index * (1 - 1%), Spot index * (1 - 6%)]
