Dear valued customers,
In order to better protect users’ interest and improve risk management control, we will adjust the price limit rules as follows:
1. Futures price limit rules will be adjusted to:
Within 10 minutes after the order is placed:
Max. bid price = Spot index (1 + 5%);
Min. ask price = Spot index (1 – 5%)
After 10 minutes:
Max. bid price = Min [Max (Index, Index*1.03 + price movement average within the last 10 mins), Index*1.25];
Min. ask price = Max [Min (Index, Index*0.97 + price movement average within the last 10 mins), Index*0.75]
2. Perpetual swap price limit rules will be adjusted to:
Within 10 minutes after the order is placed:
Max. bid price = Spot index (1 + 0.5%);
Min. ask price = Spot index (1 – 0.5%)
After 10 minutes:
Max. bid price = Min [Max (Index, Index*1.01 + price movement average within the last 10 mins), Index*1.02];
Min. ask price = Max [Min (Index, Index*0.99 + price movement average within the last 10 mins), Index*0.98]
Note:
- Index refers to spot price index.
- Price movement average within the last 10 minutes is calculated as follows:
- Using the candlestick chart data of the contract and spot index within the last 10 minutes to calculate the (opening price + closing price)/2 of every minute, then calculate the difference between the contract and the index, then take the average value from the difference between the two within the last 10 minutes.
- The above rules is applicable to all futures and perpetual contracts (including USDT futures and coin-margined futures).
- Opening long or short contracts are also limited by these rules.
- For open long or close long orders: If the order price is higher than the max. bid price, price limit will be triggered;
- For open short and close short orders: If the order price is lower than the min. ask price, price limit will be triggered.
New rules will be implemented by grayscale release, scheduled as follows:
