I can't. The delivery month refers to the month when the futures expire and the traders deliver or accept the securities according to the contract. Generally speaking, when futures are delivered on a regular stock exchange, individual investors cannot enter the delivery month, only the company account can. The first trading day of the delivery month is designated as the first notification day. Buyers will receive delivery notice at any time. When the buyer receives the notice, he must pay the contract money. Some exchanges allow buyers and sellers to deliver on any day of the delivery month.
