[//]:content-type-MARKDOWN-DONOT-DELETE To make sure the Mark Price of perpetual futures always indicates the fair price of the underlying asset in the changing market conditions, Gate.io will adjust the calculations of Mark Price to a more robust and sound mechanism. The adjustment will be implemented phase by phase, with a transitioning phase of several weeks before it is fully implemented to all perpetual futures markets. In the upcoming weeks, perpetual futures’ markets where Mark Prices deviate from the settlement prices significantly will be transitioning to the new Mark Price first. The date of full implementation will be announced in a follow-up announcement later. Below is the new Mark Price calculation rules: Mark Price=Mid (Price 1, Price2, Last Price) * Price1 =Index Price x（1 + Funding Basis） ** Funding Basis = Funding Rate x（Time Til Next Fuding / Funding Interval） * Price 2 = Index Price + 30 Minutes Moving Average ** Moving Average = MA [（Bid 1 + Ask 1）/ 2 − Index Price] Existing Mark Price Calculation： Mark Price = Index Price x (1 + Funding Basis） * Funding Basis = Funding Rate x（Time Til Next Fuding / Funding Interval） If you are a perpetual contract trader, please adjust your trading strategy accordingly.
