Stamps are an object and a valuable security. Stamps are postage certificates issued by postal authorities for posting and pasting mail. Stamps are a form for the sender to pay for postal services.

Futures is a way of trading. Futures are mainly not commodities, but standardized tradable contracts with certain mass products such as cotton, soybeans and oil and financial assets such as stocks and bonds as the targets. Therefore, the subject matter can be commodities (such as gold, crude oil and agricultural products) or financial instruments. It can also be stamps.

The biggest difference between spot trading and futures trading lies in the difference of trading objects and the limitation of commodity delivery time. The target of futures trading is a contract to be delivered in a given month in the future, and the contract has a fixed expiration time, that is, the last trading day. The price of futures trading reflects the expectation of future price, and the price is spot price+time cost. However, the subject matter of spot transaction and spot deferred transaction is spot physical object, and there is no limit on delivery time. Traders can declare delivery at any time according to their own needs. The spot transaction price is the current price.

At present, the electronic stamp tray of the exchange belongs to spot trading, which is similar to that of stocks, but it is essentially different from stocks. The electronic stamp tray has physical stamps in the stock exchange, and buyers can ask for physical stamps at any time, while stocks are bought in kind and there is no way to extract them.
