Price Index

For Price Index Computation, spot Prices of various exchanges are taken and weighted average of these spot prices are done
I want to know whether spot price from other exchanges are taken on every tick (i.e. on every trade only) or the real time other exchanges price are taken irrespective of trade is not done in that exchange). Example: Price of Exchange A ,B,C,D,E are considered for computation of Price Index. In case price of Exchange E is not available for 2 second i.e. from 11:09:07-11:09:09, then will Exchange E send spot price during above mention 2 second period

Hi @hemlata-tech , we only have access to public information and regarding Price Index, this is the article that talks about its calculation: What Are Mark Price and Price Index in USDⓈ-Margined Futures | Binance

However I think you’re question is more doubts about what is Spot Price exactly. Spot Price is the current live price of the symbol. If there’s no trade during the referred 2 seconds, the spot price remains the same.
