What is Mark price
A price averaged across several exchanges used for unrealised PnL and liquidation. It protects you from being liquidated by one stray print.
How it works
Example
The last trade on the exchange printed 62,400, while the mark price is 62,560. Liquidation is checked against 62,560.
Common mistake
Setting a stop on mark price and not understanding why it fired later than the last price.
