SpotOracle

Git Source

The SpotOracle is supposed to reflect the current market price of a collateral asset. It is used by IonPool to determine the health factor of a vault as a user is opening or closing a position. NOTE: The price data provided by this contract is not used by the liquidation module at all. The spot price will also always be bounded by the collateral's corresponding reserve oracle price to ensure that a user can never open position that is directly liquidatable.
