What is the difference between an index price, a fair price, and a most recent transaction price?

Three-Priced Definition
Index MEXC assigns varying weights to the spot prices from at least three separate exchanges, resulting in a weighted average price.

MEXC's Fair Price is the Index price multiplied by the capital cost base rate. The fair price marking method is designed to keep highly leveraged products from being liquidated prematurely. The fair price is primarily used to assess unrealized loss and position liquidation, implying that liquidation or automatic deleveraging is based on the fair price rather than the most recent transaction price.

Calculation of a Reasonable Price

Funding Rate * (Time Until Funding / Funding Interval) = Funding Basis

Index Price * (1+Funding Basis) = Fair Price

The most recent transaction price in MEXC Futures is the current market traded price.
