Description of the Invention (1) Technical Field The present invention relates to a commodity contract trading system using a computer network and a method for performing parental transactions on the system. In particular, the system and method of commodity contract trading for primary products whose quality is affected by external factors such as weather and origin. Background Art It is known that when a agricultural product is traded in a product, it is typically represented by 1) spot transactions, 2) transactions based on term contracts (commodity term transactions), and 3) futures transactions. The general spot transaction is the actual purchase and sale of goods in a spot market such as a wholesale market, and the ownership of the goods is transferred from the seller to the buyer. The term transaction is a sale and purchase transaction at a specific time in the future at a price negotiated by the buyer and the seller in advance. Futures trading is a buying and selling behavior promised by both the buyer and the seller at a specific time in the future at a price agreed at the current point in time. Contract trading also has the same characteristics as the futures trading, according to the time of signing the contract and the time of performing the contract. These two forms of trading are very similar to futures and futures, but they are very different in terms of system. Compared with futures trading, futures trading is one in which transactions can be carried out safely and effectively, and has various organizational systems not available in futures trading. Such an organization system includes, for example, a commodity exchange. The following is a description of the differences between contract trading and futures trading systems. In terms of transaction form: The contract contract is aimed at each other's parent's exchange. 'Shell ___ ___ τΛι This paper size applies the Chinese National Standard (CNS) Α4 specification (210 > < 297 mm) (Please read the precautions on the back before (Fill this page) Order printed by the Intellectual Property Bureau of the Ministry of Economic Affairs and Consumer Cooperatives 514815 A7 B7 V. Description of the invention (2) (Please read the precautions on the back before filling this page) The transaction decided by the consent of both the seller and the seller ; Futures trading is the existence of an exchange (or an accounting agency) in group trading, and it can guarantee the performance of the contract. In addition, for commodities that are traded: Futures trading is a decision based on the consent of the buyer and seller in mutual transactions; futures trading is the standardization of quality, specifications, and pricing. Then, regarding the settlement method: the term contract transaction is settlement based on delivery; in contrast, the futures transaction can be settled by the difference, and the contract can be easily terminated. In terms of transaction protection, the term contract transaction is based on the counterparty's credit; while the futures transaction is based on the advance collection of the security deposit and the re-evaluation of the price. Online-Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs In the spot transactions, due to the effects of weather changes, the supply and demand are unbalanced, so the risk of high price changes is its disadvantage. In contrast, in contractual transactions, the risk of price changes is low because the parties to the contract can freely set contractual conditions. On the other hand, the low liquidity of transactions in the market as an evaluation of ease of trading is its disadvantage. As mentioned above, futures trading is highly liquid because it standardizes the quality, specifications, and pricing of commodities and trades through exchanges. In other words, with the evolution of spot trading, contract trading, and futures trading, the liquidity of transactions has increased to form a system that is easy to carry out large-scale transactions. On the other hand, the standardization of trading commodities is the uniformity of quality specifications and Standardization is further required. Compared with spot trading, futures trading has lower risk of price changes, and trading liquidity is lower than futures trading, so in fact such transactions are not often implemented. In terms of agricultural products trading, futures trading of soybeans and corn is conducted through the Tokyo Grain Exchange. However, the so-called primary products of agricultural and aquatic products, such as fruits and vegetables, meat, fresh fish due to weather and _-5- This paper size applies to China National Standard (CNS) A4 specifications (210X29? Mm) 514815 A7 B7 V. Description of the invention (3) External factors such as the place of origin will have a large impact on quality, difficulties in quality management, consistency of quality, and standard words have their own difficulties. The quality of each product is different and has its own uniqueness. These commodities have always been traded mainly through the wholesale market. This is because when buying and selling fruits and vegetables, you must actually concentrate them and use your eyes to determine the quality, which means that the fruits and vegetables have the risk of quality changes. Therefore, fruits and vegetables in the futures and contract markets are completely untraded. However, as mentioned above, in the spot trading market, there is a risk of price changes caused by uneven supply and demand. Producers and consumers also conduct personal transactions of fruits and vegetables through computer networks such as the Internet, but as in the above markets, liquidity is low and credit risk is high. Farmers, buyers of agricultural products, local wholesale markets, agricultural material manufacturers, etc. also use the Internet to set up websites that can access information, but in the end they only provide exchange of information and not a place for transactions. In the circulation market of fruits and vegetables, in order to facilitate the large-scale transactions of most market participants, the futures trading system conducted on the grain exchange is better used. However, the quality of fruits and vegetables is not uniform. Not suitable for futures trading. Therefore, the object of the present invention is to provide a system and method for trading commodities on a contract basis, which can use the advantages of the futures trading system, reduce the risk of credit transactions during trading and provide goods, and can respond to risks of quality changes such as fruits and vegetables.
