Spot Price Indexing

Spot Price Indexing is the practice of using a specific basket of spot exchange prices to create a reliable reference price for derivative products. By taking the median or volume-weighted average of prices from multiple reputable spot exchanges, the index provides a more accurate and stable price than any single exchange could.

This index is then used to calculate the mark price and funding rates for derivative contracts. Spot price indexing is a key defense against price manipulation, as it is much harder to manipulate the global average than it is to manipulate a single order book.

It is the foundation of trustworthy price discovery in the derivative market. Developing and maintaining these indices is a critical task for data providers and protocol architects.
