The futures bill should be calculated as follows:
Position profit and loss = closing price-opening price
Whether it is profit or loss depends on your buying price or selling price. If you buy when you open a position and the closing price is higher than the opening price, then you are profitable. If you sell when you open a position and the closing price is higher than the opening price, then you are losing money.
On the other hand, if you buy when you open a position and the closing price is lower than the opening price, then you are losing money; If you sell when you open a position and the closing price is lower than the opening price, then you are making a profit.
