The first question is that the earliest futures exchange was born in the Tangdao Rice Club in Osaka, Japan, and the commodities traded were rice. 17 10 years later, Japanese businessmen can buy and sell "future rice", also known as rice rolls. You can buy unproductive rice through money, or you can sell unproductive rice for money. People's trading behavior is realized through the delivery of treasury, not in kind.
Physical transactions are spot sales. The buying and selling of futures trading is the buying and selling of futures contracts. When you buy (or sell) goods for a period of time, you aim to sign a contract.
For example, the current price of Zheng sugar is 5000 yuan/ton. If you are optimistic about 1 1, you can buy a 5000-yuan contract that expires at 2010+0/and wait for the price to rise.
Second, the problem of avoiding risks in futures trading. Compared with stock trading, the leverage ratio of futures trading is higher, generally around 10%. In other words, you can pay 10% for 100% trading. In addition, it is aimed at spot merchants. When you are ready to buy or sell the spot in your hand, you can open a contract in the futures market that is opposite to the spot trading direction to preserve the value. I wonder what the landlord is referring to.
