What we can actually buy now is called spot, for example, you want to buy primary soybeans. This is the unit in the transaction. Now you buy the spot, now it's soybeans, 80 cents a catty, 1.6 1 catty, and then you can give the money to the other party, and the other party can send you the goods. Your transaction is completed, which is called spot transaction, but the expectation of the future has not been realized, which spans time. The two sides determine the price and terms of the transaction according to a certain point in the future, and then cash it.
For example, soybeans are now 80 cents a catty, and I think soybeans may rise to one yuan or even more expensive in the future. Then I signed such a futures agreement with a dealer, and I chose to deliver primary soybeans at the price of 90 cents in the next six months. Of course, I can exercise this right or not, because I can buy call options or put options, but there is a commission rate. You have to spend money if you don't exercise.
In the next six months, he will go from 80 cents to 1.2 yuan, so I will buy it at 90 cents and then sell it to others. At that time, it will not be the spot of futures LeTV. If I directly change a catty of soybeans into thirty cents, will I make money? On the other hand, it is also possible that it will become 60 cents instead of 1.2 yuan in the future. If I still buy it at ninety cents, all the losses will be mine.
