It depends on how you do it. If you use their formula, just apply it as is (the value formula). I don't use that...I have enough formulas to remember. What I do is calculate the price of the new contract after 30 days passed. Then the value of the contract is simply the difference between the original price (at initiation) minus the new price (the one you calculated after 30 days). That amount needs to be discounted to today (day 30) using the rate of the subject currency.
