1. To put it more bluntly, futures trading deals with bills of lading that have paid part of the margin, and the margin ratio here is the margin ratio. If you take this bill of lading to the delivery warehouse of the exchange after the expiration, you have to pay the part of the payment except the deposit (of course, there are some miscellaneous expenses such as delivery fee, packaging fee and so on. ).

2. If you have 10000 yuan now, how many corn bills of lading you can buy depends on the price of the corn bill of lading when you buy it. If it is 1000 yuan, you can buy 10 copies. But this "bill of lading" is not a paper contract in reality, but a record recorded in your electronic account.

3. Buying or selling corn depends on whether you buy a "bill of lading" or sell a "bill of lading", which is different in your electronic account record. No matter buying or selling, you must pay a certain deposit first, which is the "performance bond".

4. If you sell corn, you should pay the spot corn after the expiration. If you can't take out the corn, the deposit you paid will be deducted, and you may have to pay other fines. You will be blacklisted and no one will do business with you in the future.

The contract you got is really like a piece of paper, and you can't see any value. But if you spend 1000 yuan (deposit) to buy a contract with a face value of 10000 yuan, and someone wants to sell the contract with the same face value of 9500 yuan in the market, no one will want the contract in your hand (unless you are willing to sell it at a price lower than 9500 yuan). The same principle applies to fading.

And if the price of corn goes up and someone is willing to buy your contract with 1200 yuan, you will earn 200 yuan.
