There are two provisions for the storage of natural rubber in the previous delivery rules: \x0d\ 1. Natural rubber should be put into storage before June of the following year at the latest; \x0d\ 2。 The natural rubber in the warehouse should be delivered before the last delivery month of the year after production at the latest, otherwise it will be turned into spot. The words \x0d\ are a bit awkward. In order to solve this problem, for example, if the glue obtained in September is produced this year, it can continue to be put into storage until it is delivered and sold in 65438+ 10 next year (the actual situation is unlikely); If the glue obtained in September was produced last year, it cannot be put into storage again. \x0d\ Futures delivery refers to the process that when a futures contract expires, both parties to the transaction end the expired open contract through the transfer of the ownership of the goods contained in the futures contract. There are two delivery methods: cash delivery and physical delivery: cash delivery refers to the expiration date of the contract, which calculates the profit and loss of the difference between the buying and selling price and the settlement price on the expiration date, and settles the profit and loss to the corresponding party respectively, and the period does not involve the physical delivery of the target; Physical delivery refers to the expiration date of the contract, when the seller delivers the corresponding goods to the delivery warehouse designated by the exchange according to the quality and quantity, and the buyer delivers the corresponding money to the exchange to fulfill the futures contract. General financial securities futures contracts are mainly cash transactions, and commodity futures contracts are mainly physical delivery.
