Being fined by the exchange may be higher than your delivery procedures, so you'd better close your position before delivery.

Futures is a standardized contract for the exchange to buy and sell a commodity in the next month.

Futures are characterized by small bets, two-way trading, time limit and actual profit and loss. When the futures contract is due for delivery, otherwise the exchange will force liquidation or physical delivery. The loss is deducted directly from the funds.
