The delivery period is three to five trading days after the last trading day. The last delivery date is the last delivery date. The last delivery date is the last delivery date.
At present, natural person (individual) investors do futures and are not allowed to make physical delivery. So you don't have to wait until the last trading day, and you are forced by the exchange just after entering the delivery month. The price of the exchange may not be ideal, so it is better to close the position in advance and make your own decision. )
If it is an institution or a legal person, it will face delivery on the last trading day without opening the position. If you don't deliver the goods, it is a breach of contract.
Generally speaking, there are two possibilities for compulsory liquidation. The first is that the contract expires. If you don't have a registered legal person, you will be forced to close your position if your position doesn't reach the delivery quantity. The other is that your account is short of funds, futures are settled daily, and the daily profit and loss settlement system has no debt. At the time of daily settlement, when the funds in your account can't make up for the losses of the day, you will be forced to close your position.
