The transition period duration is subject to price volatility and availability of stable index price.

What Is the Last Price Protected Mechanism?

Under the Last Price Protected Mechanism, the mark price is calculated based on the average latest transaction price of a perpetual contract within a certain limit.

Mark Price Methodology During the LPP Period:

Mark Price = Average of last 10 seconds’ trade prices, calculated every second.If there are less than 21 transaction prices in the 10 seconds interval, the system will check the number of transaction prices in the past 100 seconds. If there are more than 21, the average will be based on the transaction prices in the past 100 seconds; otherwise, it will be based on the last 100 transaction prices of the aforementioned contract.

A ±1% of price cap will be imposed on the mark price where the price change is limited within ±1% range every second interval. 

Mark Price After the LPP Period Ends:

When the LPP period of the aforementioned contract ends, the Mark Price will be calculated using the following formula:

Mark Price = Median (Price 1, Price 2, Contract Price)
