The Everstrike Index Price is an artifical price that Everstrike derives from an average of real time prices from a collection of Spot exchanges. The purpose of the Everstrike Index Price is to aid in the calculation of the Everstrike Mark Price (explained in the previous section). The Spot exchanges that contribute to the average can be seen below. To prevent price manipulation, 75% of the prices are treated as outliers, and removed from the average. The Index Price is updated at a fixed interval - currently every second.

An Index Price is calculated for each derivatives contract on Everstrike. For perpetual options, the Everstrike Index Price is the Intrinsic Value of the option (based on the Everstrike Index Price of the perpetual futures contract for the option's Underlier). If the intrinsic value of the option is zero, the Everstrike Index Price will default to 0.05% of the Everstrike Index Price of the futures contract of the Underlier.
