Spot transaction is a type of transaction that completes delivery immediately or within a very short period of time after the transaction is established. This kind of transaction has the longest history and is the most basic way, suitable for small batches and other uncertain commodity circulation. Due to the extremely short spot transaction time, "face-to-face transactions, both silver and goods", the transfer of rights between the parties and the displacement of the exchange objects are generally carried out simultaneously, so the price signal is not easy to be distorted, and competition is not easy to cause false demand.

In futures trading, a certain date is agreed upon when the transaction is established before delivery. It is suitable for transactions in commodities, securities, foreign exchange, etc.
