Price Glossary

The Foil protocol and app reference many different types of prices.

  • Resource Price: The price actually paid for the underlying resource at a given time. For example, if a block on Ethereum mainnet has a base fee per gas of 10 gwei, this would be the resource price for the timestamp on that block. This is represented by a green line in the Foil app.
  • Index Price: The average resource price over a given period. This doesn’t exist before the start time of the period and is effectively a Settlement Price estimate while the period is in progress. This is represented by a dashed blue line in the Foil app.
  • Market Price: The price that someone can buy or sell in the Foil protocol. This is represented by red and green candlesticks in the Foil app.
  • Settlement Price: The Index Price at the end of a period. After the period ends, market participants exit their positions at this price.
  • Trailing Average Resource Price: The average resource price over a previous duration. This may be useful to see what a Settlement Price would be for a hypothetical period that ended at a given time. This is represented by a solid blue line in the Foil app.
