Policies simply assess the current state of the Melon fund and resolve to a boolean decision, whether the action may be executed or fund manager trading strategy not, returning true for allowed actions and false for disallowed actions. Function removeFromWhitelist(address _who) public auth This function requires that the caller is the owner or the current contract. Order) public orderIdToZeroExOrder A public mapping a ZeroEx order identifier to a ZeroEx Order struct.
Function updateOwnedAssets public This function maintains the ownedAssets array by removing or adding asset addresses as the fund holdings composition changes. For example, the following shows risk dissected into systematic risk and unsystematic risk: We can observe that unsystematic risk can be completely eliminated from the portfolio by sufficiently diversifying or simply having a sufficient number of assets in the portfolio.

Rules coded into smart contracts that are meant to ensure that something cannot not happen in the structure of a Melon fund. Function shutDownFund public, this function sets the sShutDown state variable to true, effectively disabling the fund for all activities except investor redemptions. Function version view returns (address) This view function returns the version component contract address. In calling the revert function, gas is consumed to arrive at the reference state, but any unused gas is returned to the caller as the reference state is discarded. Note on Fee Share Allocation The intended behavior is for the Manager to immediately redeem fee shares as they are created.
This gives the ability to query registered policies for a specific function call. If the state changes do not pass the policy test, the transaction will revert and no state change will be affected. The contract will interact with the various components of the fund to calculate and return the quantity of shares to create. For the arrays, the order of the address or value in the array is semantically significant. The HWM represents the highest share valuation which the Melon fund has historically achieved at a Measurement Period ending time. Once a Policy is registered, the condition defined within the Policy will be the standard against which the policy-registered functions consequential state changes will be tested. Order Member Variables address exchangeAddress - The address of the decentralized exchange smart contact.
