What is the mark price?

A fair reference price used for unrealized PnL and liquidations, resistant to spikes on a single exchange.

The last trade price can jump for a moment because of one large order. To avoid unfair liquidations, exchanges calculate a mark price that combines the oracle price from major exchanges with the price on their own order book.

The mark price is used for unrealized PnL, margin requirements and liquidations.
