Perpetual Futures Mark Pricing

The mark price of a Perpetual Future contract can be calculated with the below formula:

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

For example, if Price 1 < Price 2 < Fair Price, then take Price 2 as the Mark Price.

The definitions for Price 1, Price 2 and Fair Price are defined below.


Fair Price

Fair Price = (Fair Impact Bid + Fair Impact Ask) / 2

The Fair Impact Bid is the average price of a $10,000 notional market sell order or *, whichever has a greater value.

The Fair Impact Ask is the average price of a $10,000 notional market buy order or *, whichever has a lower value.


Price 1

Price 1 = Index Price * (1 + Last Funding Rate * Time Until Next Funding)

Time Until Next Funding is the time left in hours until the next funding period. For example, if we measure Price 1, 30 minutes before the next funding period, it would be 0.5.

Below is an example, of how this works out:

Index Price = 2000
Last Funding Rate = 0.005
Time Until Next Funding = 0.5

Price 1 = 2000 * (1 + 0.005 * 0.5) = 2005

Price 2

Price 2 = Price Index + Moving Average (5-minute Basis)

Moving Average (5-minute Basis) = Moving Average (FairPrice - Price Index), which is continuously calculated in a 5-minute interval.
