The near-end transaction occurs before the delivery date and the far-end transaction occurs after the delivery date. Delivery is the settlement of funds between investors and securities companies in the settlement process. Generally, in order to ensure smooth delivery, users are required to keep enough margin in their trading accounts.

The delivery date is the date when the currency should be delivered when buying or selling foreign exchange. Buyers of foreign exchange should deliver their own currency, and sellers of foreign exchange should deliver the sold foreign currency.

The qualified delivery date must be the business day of the country where the currency is delivered. Even if both parties to the transaction are holidays, as long as the country issuing the delivery currency is a business day, it is still a qualified delivery day.

The delivery date can be divided into:

(1) Cash delivery date usually refers to two business days after the trading day;

(2) The delivery date of the futures exchange usually refers to the delivery date of the spot exchange plus the delivery date calculated by several months. If this delivery date is unqualified, it will be postponed. If it is postponed until next month, it is not a routine postponement, but the other way around.
