Funding Fee
The fundingFee
contract provides logic for calculating and settling funding fees, as well as querying the funding rate and pending (pre-settlement) funding fees.
basePool
Funding rates are calculated using basePool
. If for a given market the basePool
is not set (ie. set to 0x000...
), funding fees will not be applied in this market.
The basePool
address can be queried using Config.
Contract
/// #notice Check the settlement event to see amount of funding paid/received. This information may also be available from The Graph.
event FundingFeeSettled(uint256 marketId, address trader, int256 fundingFee);
function getCurrentFundingRate(uint256 marketId) public view returns (int256)
/// @notice Amount of pending fees from the trader's perspective.
/// @return When settled, margin will decrease if fee is positive, increase if fee is negative.
function getPendingFee(
uint256 marketId,
address trader
)
returns (
int256 pendingFee
)
/// @notice Query latest funding rate. Historical funding rates should be queried from The Graph or similiar provider.
function getCurrentFundingRate(
uint256 marketId
)
returns (
int256 fundingRate
)
