To be used if the margin currency is an ERC20 token rather than ETH.

Parameters:

• erc20Address: address of the ERC20 token used to pay the fee.

• amount: number of tokens to transfer. An approval for at least this amount must exist.

computeRegularFee(uint256 startTime, uint256 endTime, struct FixedPoint.Unsigned pfc) → struct FixedPoint.Unsigned regularFee, struct FixedPoint.Unsigned latePenalty (external)

Computes the regular oracle fees that a contract should pay for a period.

Parameters:

• startTime: defines the beginning time from which the fee is paid.

• endTime: end time until which the fee is paid.

• pfc: "profit from corruption", or the maximum amount of margin currency that a token sponsor could extract from the contract through corrupting the price feed in their favor.
