Method for processing an order for buying stocks based total amount of assets for ordering}

The present invention relates to a method for processing a stock purchase order over the Internet, and more particularly, to a stock purchase order processing method for determining whether a stock trader has processed an internet purchase order based on the target asset target value of a stock trader account. It is about.

In general, in order for a stock trader to buy stocks, a certain amount of margin must be secured in his account set up at the securities firm. Such margin is covered by cash and / or substitute.

For example, suppose you have more than $ 10 million in securities in a stock trader's account and $ 1 million in cash is prepaid. In this case, when a stock trader buys a stock with a 40% stock margin (10% cash, 30% substitute), it is possible to order up to 10 million won, which is 10 times cash. In this case, no matter how many securities a stock trader holds, it is impossible to order a stock purchase of more than 10 million won. In addition, even if the value of deposited securities increases, it is not possible to order new shares without cash.

Therefore, according to the conventional stock purchase order processing method, because the cash and substitute securities do not meet the business rules of the Securities and Futures Exchange, there was no choice but to accept the accusation that it was an unreasonable form of trading that ignored customers.

The present invention was devised to solve the above problems, and it is possible to determine whether the order can be made by the maximum order amount calculated on the basis of the target asset value of the customer account, which limits the amount exceeding a certain amount Its purpose is to provide a method for processing stock purchase orders.

In order to achieve the above objects, the order asset target amount according to the present invention in the method of processing the order by the server system of the securities company that receives the stock purchase order from the terminal of the customer connected through the Internet to perform the securities transaction of the customer Based on the stock purchase order processing method, (a) receiving a purchase order of a specific stock from the customer via the Internet; (b) calculating an order asset target amount, which is a limit on receivables, from the virtually settled cash and securities amounts based on the date of the customer's account plus two business days; (c) calculating a maximum orderable amount by dividing the target asset amount by the margin ratio of the stock item; (d) calculating a maximum unacceptable amount, the maximum amount of unacceptable amount that the securities firm can tolerate in the client's account; And (e) if the purchase price is less than or equal to the smaller of the maximum orderable amount and the maximum unacceptable amount, processing as an acceptable order.

Hereinafter, preferred embodiments of the stock purchase order processing method based on the order asset target amount according to the present invention will be described in detail with reference to the accompanying drawings.

First, referring to Figure 1 proposes the overall configuration of the system for performing a stock purchase order processing method based on the target asset target amount according to the present invention.

 According to FIG. 1, the securities firm server 30 may be connected to a plurality of customer terminals 10 through the Internet 20, and is connected to the stock exchange server 40 through a separate network (not shown). Here, the Internet 20 is a computer communication network connecting the world using the Transmission Control Protocol / Internet Protocol (TCP / IP) protocol, and is a broad meaning including a wired and wireless communication network connected to a user terminal in connection with the Internet. Used. In addition, the customer terminal 10 can read a Hypertext Markup Language (HTML) document, which is a standard document of the web, and a web browser (not shown) that is software that can communicate with the securities company server 30 using the HyperText Transfer Protocol (HTTP). And a personal computer capable of downloading and executing a program provided by the securities firm server 30. However, the customer terminal 10 in the present invention is not limited thereto, and is provided with a web browser (not shown) capable of reading a WML (Wireless Markup Language) document and supporting WAP (Wireless Application Protocol). It is used as a general meaning including a PDA (Personal Digital Assistant), a mobile phone, etc., which can download and execute a program provided by the server 30.

The securities company server 30 manages customer information to authenticate the customer terminal 10, the customer management unit 31, the securities information provider 32 that provides various securities information to the customer terminal 10, and purchase of stocks from customers. And a stock sales processing section 33 for receiving stock orders and processing stock trading, and a database 34 for managing various data processed by these components.

Referring to FIG. 2, the stock trading processing unit 33 of FIG. 1 includes an order input unit 331, a purchase order processing unit 332, and a sell order processing unit 333, and in particular, the purchase order processing unit 332 includes an order asset object. An amount calculation unit 3321, a maximum order value calculation unit 3322, an unacceptable target amount calculation unit 3323, a maximum unacceptable amount calculation unit 3324, and an order availability determination unit 3325 are provided. Sell order processing unit 333 is not included in the scope of the present invention, a detailed description thereof will be omitted.

The order asset target value calculation unit 3321 calculates the target asset target amount, which is a limit amount of receivables from the cash and securities amount virtually settled, on the basis of the date plus two business days from the current day in the customer's account. Equation 1 illustrates a calculation equation used by the order asset target value calculation unit 3321.

Amount subject to order assets = (D + 2) Settlement deposit-Excluded deposits + (Payment balance * Substitute price)-Substitute surplus-(Daily sale settlement * Substitute price) + (Daily purchase settlement * Substitute price) -(Today's closing balance * proxy price) + (Today's closing balance * proxy price)

Here, "(D + 2) Settlement Deposit" is the cash (deposit) of a customer account that is virtually settled based on the date plus two days from the current date,

"Excluded deposit" is the amount already used for other purposes, such as receivables, in the balance of payments.

"Payment Basis Balance" is the balance of securities in customer accounts settled as of the current day,

"Substitute price" is the price of substitute securities, which are securities specified separately by the stock exchange, to be used instead of cash to increase the utilization of securities,

The "substitute surrogate amount" is the surrogate amount of securities already used for other purposes, such as loans, in the settlement balance.

"Sale day balance" is the balance of the securities in the customer's account with which the order was placed on the previous day.

"Full-day purchase balance" is the stock balance of a customer's account with which the order was purchased the day before.

"Sell today's balance" is the balance of the securities in the customer's account with which the order was placed and sold today.

The "Buy Today's Balance" is the securities balance of the customer's account to which the purchase was made today and the order is concluded. The value for each of these is assumed to be already calculated and stored in the database 34 during the stock trading process.

In addition, when calculating the substitute amount of the settlement basis balance, the day-to-day buyout balance, the day-to-day sellout balance, the today's buyout balance, and the today's sellout balance, Equation 1 is calculated for each item It is to be understood that the sum of all amounts is added.

The maximum orderable amount calculation unit 3322 calculates the maximum orderable amount based on Equation 2 below.

Maximum Orderable Amount = Target Asset Value / Group Margin Rate for Each Item

Here, the "group margin rate for each item" is the margin rate in the group to which each item belongs. For example, the group margin is set at 20% in Group A, 24% in Group B, 32% in Group C, 40% in Group D, and 100% in Group E. Shall be. Such group margin can be flexibly configured in various ways.

However, when it is determined whether the order can be made only by the maximum orderable amount calculated by the maximum orderable amount calculation unit 3322, the purchase order of the customer is repeated and the amount of the outstanding amount tends to increase rapidly on the settlement date. Accordingly, the unacceptable amount of money calculation unit 3323 and the maximum unacceptable amount of money calculation unit 3324 serve to limit an excessive increase in the amount of unacceptable money.

The unacceptable target amount calculation unit 3323 calculates the unacceptable target amount, which is the sum of the current deposit and the surrogate amount settled based on the current date, as illustrated by Equation 3, but the securities that have been sold out of the settlement balance today It is calculated by reflecting the selling amount instead of the surrogate amount.

Unacceptable Amount = Deposit-Excluded deposit + (Payment balance * Substitute price)-Substitute surrogate amount-(Today's settlement balance among settlement basis * Substitute price) + (Sale of payment basis among settlement basis)-(Payment) Full-day selling balance among standard balances * Substitute price) + (Daily-sale amount among payment-based balances)

Where "deposit" is the current cash (deposit) in the customer's account,

"Excluded deposit" is the amount already used for other purposes, such as receivables, in the balance of payments.

"Payment Basis Balance" is the balance of securities in customer accounts settled as of the current day,

The "substitute surrogate amount" is the surrogate amount of securities already used for other purposes, such as loans, in the settlement balance.

"Sell today's settlement balance of payment basis" is the number of securities that have been sold today.

"All-day selling balance among payment-based balances" is the number of securities that were sold the day before.

"Sell today amount in the balance of payment" is the amount of sales of securities that have been sold today in the balance of payment.

The "day selling amount in the settlement basis balance" is the selling amount of the securities for which the sale was made in the previous day among the settlement basis balances, and values for each of them are already calculated and stored in the database 34 during the stock trading process.

In addition, when calculating the balance of the settlement basis balance and today's selling quantity in Equation 3, it should be understood that when the number of the corresponding stock items is a large number, the amounts calculated for each item are added up.

The maximum unacceptable amount calculation unit 3324 calculates the maximum unacceptable amount by the following equation (4).

Maximum Amount Unacceptable = (Unacceptable Amount / Group Margin Rate for Each Item)-Unacceptable Amount + (D + 2) Household Settlement Deposit-Amount Not Ordered

Here, the "non-trading order amount" refers to the amount of money that has not been concluded from the purchase order amount on the basis of the present.

The order availability judging unit 3325 processes an acceptable order if the total purchase amount is less than or equal to the smaller of the maximum orderable amount and the maximum unacceptable amount.

In the above equations, the amount of various securities was calculated by multiplying the surrogate price by the quantity of the securities, and the scope of the present invention is not limited thereto. It may be easily understood by those skilled in the art that the combined price may be adopted by giving a predetermined weight to the price, the previous closing price and the present price.

Hereinafter, with reference to Figure 3 will be described in the stock sales processing process applied to the stock purchase order processing method based on the order asset target amount according to the present invention.

When a customer buys a stock through his or her customer terminal 10, the customer selects the stock purchase or stock selling to place an order (S100, S200).

First, when a customer wants to buy stocks, a stock purchase order in which a trading item and a trading quantity are set is input to the customer terminal 10 (S110). The stock purchase order input to the customer terminal 10 is transferred to the order input unit 331 of the securities firm server 30 through the Internet 20. Thereafter, the customer may select the general margin rate method according to the conventional method or the margin rate (hereinafter referred to as MAPS margin rate) method according to the present invention (S120).

When the customer selects the MAPS margin rate method according to the present invention, the order asset target amount is calculated by the order asset target amount calculation unit 3321 (S130), and the unacceptable target amount calculation unit 3323 is not allowed. The amount is calculated (S140). Thereafter, the maximum orderable amount calculating unit 3322 and the maximum amount of unacceptable amount calculating unit 3324 are reflected in the group margin rate for each item to calculate the maximum orderable amount and the maximum amount of unacceptable amount (S150 and S160).

The order availability judging unit 3325 recognizes as an acceptable order if the total amount of the purchase amount is less than or equal to the smaller of the maximum orderable amount and the maximum unacceptable amount. The stock purchase processing unit 33 performs the stock purchase process targeting the allowable order (S190).

On the other hand, when the customer selects the general margin rate method to calculate the reuse amount by applying a margin rate of 40% (100% in the case of managed items, etc.) and calculates the amount available for ordering (S170, S180). Since this method is not an area of the present invention, further description will be omitted.

On the other hand, even if the customer wants to sell the stock is entered into the order to sell the stock and the amount of the trading stock to the customer terminal 10 (S210). The stock sell order input to the customer terminal 10 is processed by the sell order processor 333 via the order input unit 331 of the securities firm server 30 through the Internet 20. Since the stock selling process is not an area of the present invention, further description thereof will be omitted.

FIG. 4 illustrates a stock purchase order processing process based on an order asset target amount, and schematically illustrates that a group margin ratio is applied to each item in steps S150 and S160 of FIG. 3.

For example, suppose that a customer with 1 million won in cash purchases an item belonging to group A (20% margin) for 500,000 won, and then obtains an additional purchase amount for an item belonging to group C (32% margin). .

At this time, the order asset target amount is calculated by Equation 1 as follows.

500,000 won [(D + 2) Settlement deposit]-0 won [deducted amount of deposit] + 0 won [Payment basis balance * substitute price]-0 won [substitute surplus amount]-0 won [sold day closing balance * substitute price ] + 0 won [Full day purchase balance * proxy price] + 0 won [(Today sale balance * substitute price)]-350,000 won [(Today buy balance * substitute price)] = 850,000 won. In this case, the reason why (Buy Buying Balance * Substitute Price) is set at 350,000 won is calculated by calculating 70% of the weight applied to substitute proxy price.

The unacceptable target amount of money is calculated by the following equation.

1 million won [deposit]-0 won [deposit amount excluded] + 0 won [payment balance * substitute price]-0 won [substitute surrogate amount]-0 won [today's settlement balance of settlement balance * substitute price] + 0 won [ Today's payment amount in the payment balance]-0 won [Full-time sale balance in the payment balance * Substitute price] + 0 won [Daily sale amount in the payment balance] = 1,000,000 won

The maximum orderable amount is calculated by the following equation.

KRW 850,000 [Amount subject to purchase order] / 32% [Cross margin rate for Group C] = KRW 2,656,250

The maximum unacceptable amount is calculated by the following equation.

1,000,000 won [Unacceptable Amount] / 32% [C Group Margin Rate]-1,000,000 [Unacceptable Amount] + 500,000 Won [(D + 2) Account Settlement]-0 [[Amount of Unpaid Purchase Order] = 2,625,000 won

Therefore, the orderable amount is Min [2,656,250 won, 2,625,000 won] = 2,625,000 won.

So far I looked at the center of the preferred embodiment for the present invention. Those skilled in the art will appreciate that the present invention can be implemented in a modified form without departing from the essential features of the present invention. Therefore, the disclosed embodiments should be considered in descriptive sense only and not for purposes of limitation. The scope of the present invention is shown in the claims rather than the foregoing description, and all differences within the scope will be construed as being included in the present invention.

According to the present invention, when a customer places an order for stock purchase, instead of the existing reuse amount, the order asset amount and the unacceptable amount are calculated, and the orderable amount is weighted for each item to calculate and apply differentially. As the actual margin ratio of individual stocks is prevented from being distorted, and the order assets held by the customer are calculated as the real-time orderable amount, when the price drops, the target amount of the customer's order assets decreases and the orderable amount decreases. It enables automatic risk management in downmarkets.

In addition, although the cash was inevitably required for the existing stock trading, the present invention enables the stock trading only with substitute securities, even if there is no cash, so that the customer's assets are substantially assessed, so as not to distort the valuation. By enabling stock trading, a rational trading culture can be formed.
