What is Index price

A weighted average of an asset's price across several spot exchanges; the futures mark price derives from it, so one venue's bad price cannot move liquidations.

How it works

Example

Three spot exchanges show 62,000, 62,100 and 62,300 with weights of 50, 30 and 20%. The index: 31,000 + 18,630 + 12,460 = 62,090.

Common mistake

Comparing the futures chart with some other spot chart and calling the gap manipulation: the futures contract has its own price, and the index is just the spot average.
