function marketPrice() external view returns (UD60x18);

Returns

takerFee

Calculates the fee for a trade based on the size and premium of the trade

function takerFee(address taker, UD60x18 size, uint256 premium, bool isPremiumNormalized, bool isOrderbook)
    external
    view
    returns (uint256);

Parameters

Returns

_takerFeeLowLevel

Calculates the fee for a trade based on the size and premiumNormalized of the trade.

WARNING: It is recommended to use takerFee instead of this function. This function is a lower level function here to be used when a pool has not yet be deployed, by calling it from the diamond contract directly rather than a pool proxy. If using it from the pool, you should pass the same value as the pool for strike and isCallPool in order to get the accurate takerFee

function _takerFeeLowLevel(
    address taker,
    UD60x18 size,
    UD60x18 premium,
    bool isPremiumNormalized,
    bool isOrderbook,
    UD60x18 strike,
    bool isCallPool
) external view returns (UD60x18);

Parameters

Returns

getPoolSettings

Returns all pool parameters used for deployment

function getPoolSettings()
    external
    view
    returns (address base, address quote, address oracleAdapter, UD60x18 strike, uint256 maturity, bool isCallPool);

Returns

ticks

Returns all ticks in the pool, including net liquidity for each tick

function ticks() external view returns (IPoolInternal.TickWithRates[] memory);

Returns

claim

Updates the claimable fees of a position and transfers the claimed fees to the operator of the position. Then resets the claimable fees to zero.

function claim(Position.Key calldata p) external returns (uint256);

Parameters

Returns

getClaimableFees

Returns total claimable fees for the position

function getClaimableFees(Position.Key calldata p) external view returns (uint256);

Parameters

Returns

writeFrom

function annihilate(UD60x18 size) external;

Parameters

annihilateFor

This function can be called post or prior to expiration.

function annihilateFor(address owner, UD60x18 size) external;

Parameters

Exercises all long options held by caller

function exercise() external returns (uint256 exerciseValue, uint256 exerciseFee);

Returns

exerciseFor

Batch exercises all long options held by each holder, caller is reimbursed with the cost deducted from the proceeds of the exercised options. Only authorized agents may execute this function on behalf of the option holder.

function exerciseFor(address[] calldata holders, uint256 costPerHolder)
    external
    returns (uint256[] memory exerciseValues, uint256[] memory exerciseFees);

function settle() external returns (uint256 collateral);

Returns

settleFor
