You can change the chart view from selecting between:&#x20;

* Index Price
* Mark Price
* Predicted Funding Rate

The *mark price* is usually updated in real-time during trading hours and can change frequently, depending on market conditions. It is an important indicator for traders and investors, as it provides an estimate of the fair value of a futures contract or option at a particular point in time.

The *index price* is calculated by taking the weighted average of the prices of all the stocks included in the index. The weight of each stock is determined by its market capitalization, which is the total value of all the outstanding shares of a company.
