Detailed Description
in order to make the technical means, creation features, achievement objectives and effects of the present invention easy to understand, the following embodiments are specifically set forth for the system of trading the bulk chemical commodities based on the difference between the acquisition and the sale price in combination with the accompanying drawings.
as shown in fig. 1, a bulk chemical commodity futures trading system 100 based on a stock spread comprises: financial module 10, field management module 20, transaction module 30, settlement module 40.
The financial module 10 is used for depositing and managing funds transferred by a transaction subject, paying the amount of a transaction order, making a cash withdrawal, etc. The transaction body establishes a transaction account of the individual before depositing the money to the financial module 10, and then deposits the money to the transaction account of the individual. In this embodiment, the financial module 10 is a mockson, and the user needs to open the mockson to establish a personal transaction account.
the spot management module 20 is used for creating a spot, setting a spread trading rule, creating a trading order according to a purchase order and a sale order of a trading subject in the spot, creating a trading chain according to the trading order, freezing a collecting and selling spread of the trading subject required to trade in the spot in funds stored and managed in the financial module 10 according to the set spread trading rule, and notifying the trading subject according to the starting time of the spot.
The spot is created by the trader through the spot management module 20 according to the purchase orders and sales orders of each trading entity on the trading platform 200. The transaction platform 200 is like a Taobao website, and has a merchant issuing goods for sale and a buyer buying goods for sale on the website. In this embodiment, the trading platform 200 is a mocbei platform trading system. The spot management module 20 can create a plurality of spots as needed, as shown in fig. 2. After the places are established, a trade order is required to be established according to a purchase order and a sale order of a trading subject, a trade chain is established according to the trade order, and one trade chain is established in each place.
As shown in fig. 3, each trade order includes a sales order and a purchase order for the same commodity, and each trade chain is composed of a plurality of trade orders. The ordering rule of the trading orders in each trading chain is as follows: the trading subject of the sales order in one trade order is the trading subject of the purchase order in the upstream trade order, and the trading subject of the purchase order in the trade order is the trading subject of the sales order in the downstream trade order.
For example, in FIG. 3 a trade order is: order numbering: MS2019061900000026, supplier: jiaxing xxx limited, interview: fuzhou xxx company, Inc., trade name: xxx, unit price of commodity: 4505.00 yuan/ton, amount: 500.00ton, total price: 2252500.00 Yuan, order status: to be paid.
the chain of transactions in fig. 3 is shown in table 1. The sequence of trading orders in the trading chain is from top to bottom in table 1.
TABLE 1
The spread transaction rules are: the frozen funds that the transaction subject needs to freeze are determined based on the difference between the amount of purchased merchandise and the amount of sold merchandise. The frozen fund is the difference between the acquisition and the sale in the special field. As shown in fig. 4, the spot management module 20 freezes the acquisition and sale difference that the trading entity needs to trade in the spot among the funds held in the financial module 10 according to the set spread trading rule. For example, in the chain of transactions in Table 1, Shaanxi xxx Limited needs to freeze 2253000.00 yuan, Fuzhou xxx Limited needs to freeze 72500.00 yuan, and other companies do not need to freeze funds.
Prior to the start of the spot, the spot management module 20 checks the funds account of each transaction body to confirm the blocked funds and the account total funds. If the total fund of the account of the transaction main body does not meet the difference of acquisition and sales, the special field management module informs the transaction main body to recharge; if the total funds of the accounts of all transaction subjects meet the acquisition and sale difference, the starting conditions of the spot are met, and the spot can be started when the starting time of the spot is reached; and if the total account fund of the transaction main body does not meet the acquisition and sale difference after the time for starting the spot is up, the spot is failed to start. And prompts the reason for the failed start-up.
As shown in fig. 5, after the spot is started, the transaction module 30 completes the transaction in reverse order from the transaction main body at the end of the transaction chain to the first transaction main body in the transaction chain according to the transaction chain created in the spot. Taking the transaction chain in table 1 as an example, the transaction chain is completed by paying first from shanxi xxx ltd, the transaction body at the end of the transaction chain, and then paying in order from yibin xxx ltd, fujian xxx ltd, shanghai xxx ltd, and fuzhou xxx ltd, the transaction chain is completed, and the field is finished.
In this embodiment, before the trading module 30 performs trading, the trading subjects need to confirm the trading order information to ensure that the purchase information and the sales information of each trading subject are consistent with the trading order when the trading chain is established. After confirming the transaction order information, each transaction agent starts to perform the transaction. The trading module 30 trades only trade orders in the trade chain for which trade order information has been confirmed.
in this embodiment, as shown in fig. 6, when the transaction module 30 performs a transaction, the transaction agent needs to complete order payment and uploading of the right voucher, and after the upstream transaction agent confirms the right voucher uploaded by the downstream transaction agent, the single transaction is completed. For example, taking the transaction chain in table 1 as an example, after payment is made by shanxi mobei biotechnology limited, the right of purchase voucher needs to be uploaded, and after confirming the right of purchase voucher of shanxi xxx x limited, yibin xxx x limited completes the transaction, the transaction order with order number MS2019061900000029 can be traded.
in this embodiment, when performing a transaction, the transaction module 30 determines, according to the spread transaction rule set by the spot management module 20, whether each transaction subject provides the acquisition and sale difference required by the transaction chain transaction before the transaction, if so, the transaction can be performed normally, and if not, the spot transaction can be processed according to an exception, which supports thawing of the transaction surplus of each transaction subject that has completed the transaction, releases the frozen funds of each transaction subject that does not participate in the transaction, and releases the payment and the frozen funds of the transaction subject that purchased the order in the transaction chain exception node. Whether the frozen funds of each transaction main body meet the acquisition and sale difference is further confirmed in the transaction process, so that the transaction safety is further ensured, and the fund safety of each transaction main body is ensured. When each transaction main body is in transaction, if the system is abnormal before the start of a special field, the frozen fund of a certain transaction main body does not meet the acquisition and sale difference of the transaction chain; or after the order of the transaction main body is changed, the frozen fund of the transaction main body does not meet the acquisition and sale difference of the transaction chain; or after a certain trading subject cancels a purchase order or a sale order, when the frozen fund of the trading subject in the trading chain does not meet the acquisition and sale difference of the trading chain and the like, the trading chain is wrong, the trading error is avoided, the trading disorder is avoided, and the trading subject is lost.
For example, taking the trade chain in table 1 as an example, if the frozen amount of fuzhou xxx ltd is less than 72500 yuan, the spot trade is abnormal, and when the spot trade carries out a trade order with the number of 2 and the order number of MS2019061900000027, the system prompts that the trade is abnormal, and defrosts the trade surplus of shanghai xxx ltd, fujian xxx ltd, yippen xxx ltd and shanxi xxx ltd which have completed the trade. Release frozen funds from the carrier and upstream non-transacting transaction subjects. For a trade order with a trade chain abnormal node, namely the number 2 and the order number MS2019061900000027, frozen funds and receivable payment of a buyer company (namely a trade subject of a purchase order: Shanghai XXXX multiplied by limited company) of the node are released. This ensures transaction security and fund security for each transaction agent.
The settlement module 40 calculates a transaction surplus of each transaction subject according to the transaction completed by the transaction module 30, and changes the transaction surplus from a frozen state to a presentable state according to the application of the transaction subject. And selling and collecting the price difference when the transaction is surplus. The sale and collection price difference is the difference between the amount of the commodities sold by the transaction main body and the amount of the commodities purchased by the transaction main body.
The settlement module 40 also confirms the invoice of the single order when the transaction surplus is changed from the frozen state to the cashable state. After the spot is finished, each transaction main body appoints according to the actual settlement date, the invoice of the single order of the spot transaction is uploaded before the settlement period, the thawing spot is applied for selling and collecting the price difference, and after the spot transaction operator finishes thawing application and audit, the surplus fund of the spot transaction is changed into the cashable state from the frozen state. The approved transaction subject of the thawing application can extract the surplus (sale and acquisition spread) of the spot transaction for other businesses through the service provided by the financial module 10.
the bulk chemical commodity futures trading system based on the acquisition and sale price difference ensures that different customers can deal according to a uniform rule, and simultaneously ensures that the same system provides independent trading and settlement services for different login users, so that the trading is safer.
By using the system for trading bulk chemical commodity futures based on the acquisition and sale spread, a trading subject needs to complete qualification certification firstly, and the qualification certification comprises the following steps: the method comprises the steps of registration authentication of an account of a transaction platform, shop opening of the transaction platform and payment tool opening.
