Mark Price is designed to provide a stable reference price for unrealized PnL and liquidation calculations.

​
Calculation

The final mark price uses the median of multiple reference prices:
Where:
  • Price 1 is derived from the index price and funding basis.
  • Price 2 is derived from the spot index and a moving-average basis.
Additional safeguards can limit short-lived abnormal deviations before normal mark-price updates resume.

​
Uses

Mark Price is used for:
  • unrealized PnL;
  • position value;
  • liquidation calculations;
  • margin-related calculations.
