1. Mark Price:
The mark price is another important factor in derivative trading. It is used as a reference for triggering forced liquidation and also for calculating leverage and unrealized profit and loss. The purpose of the mark price is to ensure fair forced liquidations and prevent market manipulation.
2. Index Price:
Index price trading, or simply index price, refers to the average spot price of a token across several major exchanges. Typically, the index price of a currency may vary between exchanges, depending on which platforms are considered as "major exchanges." Only data from these exchanges will be taken into account.
3. Last Price:
The last price is the price of the most recent trade in the derivative contract and is updated in real-time. The mark price is used to calculate unrealized profit and loss, while the latest price is used to determine realized profit and loss.
※ Due to this nature and calculation method, the latest price may differ from the mark price.
