Index price calculation check
Normally position notional is calculated by multiplying your position size by the asset's mark price. However, when index price diverges from mark price by 10% or more, the position notional is calculated by multiplying position size by the asset's index price. This serves as an additional check before triggering liquidations during severe or anomalous market conditions.
Profit & Loss
PnL is calculated using both Mark Price and 15 minute TWAP of Mark Price; the higher of the two values is used when evaluating liquidations conditions.
