Abstract

PURPOSE: A system for automatically trading securities is provided to search an item using a condition with respect to market information, rumor information, news information, and analyst evaluation information between nations. CONSTITUTION: A database receives interest rate information(283), foreign market information, a rumor, a rumor evaluation(282) of an analyst, a published item, evaluation information of an analyst with respect to a public notice, etc. from an external data server using a wire/wireless communication network. At this time, a CPU performs a search of each data received in an information source(285) using address information(204) of the data. For example, data "101010 0101010" are searched by address information "101010" which is searched by a CPU, and information of a war of the outbreak of war "010" and evaluation grade information of an analyst "010" are recognized. Thus, an unlimited extension with respect to a condition which uses foreign market information, a rumor, an evaluation of an analyst, and news as an input condition are achieved. An automatic purchase/sale deciding module which uses a CPU searches data in accordance with input conditions(201) according to accounts, and searches an item and an account which generate a purchase and sale signal.

Description

The auto-trading system for securities using expanded trading strategy and a searching engine}

The present invention relates to an item search and automatic trading system used for trading securities such as futures, bonds, and stocks, and the existing item search and automatic trading system includes an analysis of analysts, such as news, rumors, disclosures and disclosures. This did not reflect the level of human transactions.

In addition, the existing automatic trading program has a limit that the mechanical buy / sell trading signals are generated even in the deception. In addition, there is a limit to the lack of reliability in the automatic trading program to sell / split selling at a specific price.

Automated trading systems that sell at existing target prices lose the additional benefit from the event. In addition, if there are downsides in won and% from the buyback, if a stop loss occurs, a stop loss occurs frequently in the short term and needs to be compensated.

Meanwhile, conventional English-Korean translation technology and inter-language translation technology in Internet chat have become popular. On the other hand, the logic language used in conventional system trading needs to be compensated for the disadvantage that requires a high level of knowledge.

In order to compensate for the above problems, an item search is performed using conditions for information such as market information, rumor information, news information, and evaluation information of an analyst, which are received using wired / wireless communication networks. will be.

In addition, by incorporating the existing translation technology to input by the method of natural language input is to be automatically translated into a logic language.

The target data is used as reference data for holding trades to reflect expected returns. At this time, it is intended to supplement the existing mechanical automatic trading by providing services that can be made stop loss and additional purchase with an extended trading strategy that tracks the change pattern of the separation degree with respect to the reference data. Through this, we want to respond to changing market conditions.

It is another object of the present invention to ensure stable transactions by providing an update service of input data and a user's approval request service for the generated trade signals and trade pending signals through linkage with wars, analyst evaluations, and stock price prediction graphs. I would like to.

In order to achieve the object of the invention described above, the conditions input by the method of natural language input and direct drawing by a mouse are translated into a logic language by incorporating existing inter-language translation techniques. At this time, the item search engine searches according to the input conditions for various information such as input information and rumor of the analyst list. The search results are used for notification and automatic trafficking to users through wired and wireless communication networks.

Automatic buying / selling signals are generated according to the traded items and the specific items in the retrieved items, and the trades are held in accordance with the change pattern of the separation degree with respect to the reference data. In addition, all the input conditions in the present invention is updated by the information source linked through the wired or wireless communication network.

Hereinafter, the present invention will be described in detail with reference to the embodiment. In the present invention, in FIG. Buying / selling signal generation step, c) trading pending and new trading signal generation step that tracks the change of the separation distance with respect to the reference data, d) notification of search information using wired / wireless communication network, user approval request and notification of execution information Is provided.

In FIG. 1, a user computer 10, an analyst computer 12, a stock exchange computer system 17, and a securities company computer system 15 connected by using a wired communication company communication network 18 and a wireless communication company communication network 19. Steps a) and d) are performed on the network constituted by Steps b) and c) may be performed using a user computer 10 and an analyst computer 12 in addition to the securities company computer system 15. At this time, the information is received using the network interface 25, while the data processing unit 24 which gives address information to the data, the database (DB) 22 having the storage information in the storage medium 23, and the CPU 21 The central processing unit is configured to process buy / sell orders.

The CPU 21 and its operating program compare with the input data from the database 22 and retrieve it in order of accuracy. At this time, the retrieved item is notified to the user or an automatic order is made. Notification and approval requests are made to users using notification technology using e-mail, mobile phones, etc., which are known technologies using wired and wireless communication networks.

2 is a flowchart showing a stock trading process. Here, the database 22 is an interest rate information (283), foreign market information, rumors, analyst rumor evaluation (282), disclosure items, evaluation of analysts from the external data server 10 using a wired or wireless communication network Receive information and the like. At this time, the CPU searches for each data received from the information source 285 using the address information 204 of the data.

As an example of the search, the data '101010 0101010', which is information of the 'War outbreak and the analysis rate of the analyst', is searched by 101010, which is address information 204 searchable by the CPU. And it recognizes the information '010' of the outbreak of war and '1010' rating information of the analyst. The information at this time may be searched by the address information and included in the graph of the target item to be visualized. This visualization is shown in FIGS. 8 and 9.

This enables infinite expansion of the conditions for using foreign market information, rumors, analysis of analysts, and news as the input conditions for human judgment. In addition, a method of finding necessary input conditions using a database of past markets downloaded through wired and wireless communication networks can be used.

In addition, the automatic buy / sell determination module using the CPU searches for data and accounts generating a trading signal by searching data according to the input condition 201 for each account. In this case, the account that satisfies the purchase condition is bought according to the quantity condition, and the account that satisfies the selling condition is sold according to the input condition among the number of shares held.

In addition, according to the closing information is updated according to the transaction decision of the account and if the sale order is not concluded on the same day, the same order is issued until the conclusion.

The present invention tracks a pattern in which the distance is changed after the sale using the reference data based on the purchase price and the target price, the reference data based on the selling price, and the condition of the separation of the reference data. In this case, the input condition using the extended trading strategy is used as in the search condition. At this time, the reference data is relative and the input condition for the graph pattern is used as the trading condition to track the rise over the target price.

Once held for sale, the buy / sell signals that occur in the absence of other input conditions are automatically canceled. Such a transaction may be requested for user approval through a wired or wireless communication network. As a result, the user's subjectivity is reflected in the system trading, and thus trading strategies and tactics seen in arbitrary transactions made by humans can be reflected.

In addition, by using a wired or wireless communication network, it is possible to set an update condition for the information and update the information by the information source of the input condition of the user without directly inputting by the user. In other words, it is possible to respond to the trick of selling the analyst's valuation information or targets to sell signals in the upswing period by holding the sales on the basis of the trading signals and trend information of the existing technology.

3 shows an example of a lookup table according to the present invention. In the previous search 301 at the top of the table, the previous search condition 302 is input. At this time, A '(rise of search item), A (price of search item), B (three-day moving average line of search item), pattern C (rising of MACD, the technical indicator entered), G (technical indicator The decrease in DMI, the patterns D (rising), K (rising), and J (rising and small fluctuations) constitute one condition by logical operation symbols, where the search condition 302 is A '> 0. The rise in stock price is first declared as an input condition, and the following conditions are added to the logical sum (and) to form an input condition, where all natural terms can be input by incorporating existing translation techniques as shown in FIG. The input condition using the natural language input is automatically translated into a logic language, and a detailed description thereof will be described with an example in FIG. 10.

As an example, in FIG. 3, the automatic trading table includes the search pattern selection columns 318 and 328 of the search target 306, the primary 310, and the secondary 314, the selection columns 311 for the logical operation, and the conditions of the third order or higher. There is a check box for 315. In addition, the search range is limited by the reference time 360 condition.

The logic language is executed by pressing the trade table confirmation button 390.

In this search 303 of FIG. 3, 'pattern number 2' of the inverted hammer pattern 1 is selected 309 as the primary condition. At this time, as a method of inputting, a natural hammer input method called 'inverse hammer type pattern' 380 was input to a computer keyboard. In this case, detailed information such as the% unit, the range ending in% unit in% unit, etc. of the method of extending the rod using the mouse 325 may be input in the figure displayed on the screen of the computer. In addition, inputting the content 351 in the natural language of the supplementary description 350 is converted to a logic language.

As an example of input of the extended trading strategy of the present invention, 'neutral analyst evaluation and shares with a disclosure within two days and shares with two or more days' increase may be used as input conditions. In this case, the searched information may be selected by the search information notification 399 to notify the user.

Each of the search conditions may extend the search condition 381 using a logical operation. For example, if you input '(Pattern C or Equation W)' using the independent pattern C and Equation W in the existing program, if only one of the two conditions declared as independence is satisfied, do.

4 shows the first input table of the automatic buy / sell condition input. First, an item search engine 401 was selected 402. At this time, the automatic sell / buy time determination module analyzes the purchase point within three items that are the search item constraints (407, 408) when the search conditions 403, 404, and 405 satisfy the buying condition. do. On the other hand, if the selling conditions are met, the selling point is analyzed. At this time, the purchase quantity condition 409 can be input in won,%, and weekly units.

An input number 1 440 is shown as an example of the input of the automatic trade 442 for a specific item. First, the trading start date of automatic trading (403), the standard selling price (444) and the trading limit (449) were entered as amounts in won (450). The input condition of such a time unit can be realized by the method of searching time information in a computer at the time of a search. As shown in FIG. 4, the first selling standard price 444 in won and percent units and the range selection value of the upper and lower limits thereof are selected as the trading conditions.

At this time, if the transaction price satisfies the set conditions of 'within the top 30%' (454) and 'within the bottom 10%' (455), the transaction start date (443) is 2002, December 12 (445) and 9 o'clock ( At 446) trading begins. These input conditions guarantee an expanded trading strategy.

Then, a separation degree condition 492 is selected 491 for the time unit 494, the circle and% unit, and the reference data having a column 397 for inputting the change pattern, and (-) 1100 won is entered.

In addition, a strong decline pattern (499) of the moving average was chosen. In this case, it is assumed that the user inputs the input condition of the unit of circle and% which defines the strong drop pattern in advance.

In FIG. 4, a natural language may be input in the condition input fields 481 and 482 shown in the logical operation 480, or may be directly input in the input condition field 432. At this time, the shape and input method of the input table can be variously modified.

Unlike the loss-of-payment, which is input in units of won and% for the existing mechanical number, the separation condition for the reference data of the present invention is relative to the reference data, and if the specific pattern is displayed by tracking a graph of change in the separation degree for the reference data, I think this is met. At this time, the input condition can be extended to infinity by logic operation. For example, an input condition such as 'satisfaction of the separation degree condition for 1 hour' is possible.

5 is a second input table of an automatic buy / sell condition input.

In the automatic buy / sell condition input 501, the primary 504 condition was input by inputting the 'concave pattern' 515 in natural language. At this time, the detailed condition 512 of 'more than 4%' was determined by the mouse drag 519 in the pattern picture displayed on the screen of the computer. The picture constructed by the mouse drag at this time is converted into logic language. The second condition (507) was selected as 'the rising condition of the composite stock graph (+)' and the logical product (and) (505) was selected.

As the selling condition (531), the primary (533) conditions were entered in the 'convex form' of the stock price graph and 'more than -5% of the current price'. And the fall in US stocks (550) was entered as a secondary condition.

Since trading of securities is difficult to realize in all trading, it is necessary to buy additional stocks that have a tendency to succeed. Therefore, the additional buy condition 551 was set. In this case, in the unit of time (563), select 'within two days' (567), in won and%, based on the reference data (561) +1000 won (566) reflecting expected revenue (414, 418, 424). , 428), 'reference data + 20%' was entered. This represents a rise of W1,200 on the basis of the purchase. The input conditions at this time can also be extended to infinity by connecting other conditions using logical operations.

As the input condition, the linking condition 582 was selected 581, and the condition for holding on hold (584) was selected as the input condition (589). Using the analyst list-reference data 585, updates to the reference data can be executed automatically.

Since the operation is extended using the logical operation, the inter-sale hold condition 657 of the trade number 1 input in the trade conditions of FIGS. 4 and 5 may be set. After the 1st auto trade, the 2nd auto trade will be done only after the condition of withholding the sale of the extended conditions by the input method such as the trade conditions.

In this case, the extended trading strategy may be used. In the input field 658 of FIG. 6, 'increase inverse separation for two days at a higher price' may be input by using a natural language input method. In this case, the reverse separation refers to the separation at the top of the reference data. In this case, it can be extended again using a logical operation condition, a time unit, a circle and% unit for reference data, and a pattern condition 41. For example, it can be entered as 'Stop more than two days', 'Logical and', and '-20% of the sell'.

In FIG. 6, a limit on the number of transactions 601 may be used as an input condition. In the input field 605, 'three times or less per hour' was input.

There is cash weight reference data 621 for trading by an automatic trading system that will take a long time. In this case, the input conditions of FIG. 6 include the 'relative value of the composite stock index in which the comprehensive stock index is 1000 as 100' and the second (625) conditions of 'up and down 5% when the composite stock index falls'. The condition is formed by logical OR.

The trading loss limit setting (641) is a condition of 'loss of -0% of purchase' (645) in the whole transaction, and the condition for the whole transaction is set higher than the stop loss of each item. This prevents the loss of transactions in securities such as securities to continue to be carried out. In addition, priority among items of other interworking conditions 651 and priority between information sources within items may be specified.

7 is an automatic selling table for explaining an embodiment of automatic buying / selling of the present invention. The following embodiment does not limit the scope of the input condition of the present invention to an automatic trade table that performs auto trade based on the inputted input condition.

First, FIG. 7 automatically trades using a specific moving average line 703 as a 10 minute rod. The target stocks fell due to the low dividend rumor 704, but the consolidation 729, which is a buying condition 721, occurred due to an increase according to the disclosure 707. At this time, it was identified as 'concave pattern' in the stock graph and bought at 708 won per week (708). The first 'convex pattern' is -1100 won in terms of the reference data and the degree of separation, compared with the -500 won line.

The second stock price graph 'convex pattern' occurred at KRW33,000, which met the expected profit of ￦ 1,000 + (744), which is used as the reference data (742). 710).

As a result, the expected return on purchases was W1,000 and an unexpected return of W2,000 was obtained.

On the other hand, the number of recommendation of the analyst list in the information source inputted by the user as a linkage condition in the graph is also shown in the graph by searching by time information and address information. In the same way, news such as wars can be visualized on a graph where all market conditions are viewed by the user.

As another assumption, in case 2 (714), when the actual price drops to the highest price of 35,000 won, the space of 29,000 won is satisfied by the selling price of -1100 won (711) for the reference data and becomes a selling condition (712). However, the selling condition is not satisfied due to the 'expansion pattern of separation' on the reference data, which is another condition, so that the selling is not possible. This means that a service that can track the change pattern of the separation degree with respect to the reference data using the extended input condition is provided. In this case, the logical condition is used as an input condition, 'surge of separation', 'average value of separation in time unit', 'more than two convex patterns of separation in time unit', 'maximum separation degree of reference data within set time unit' And the like can be used. At this time, all the input conditions are searched whether these input conditions occur in the graph by the existing logic language search technique and the existing pattern recognition technique.

8 is an automatic selling table for explaining an embodiment of automatic buying / selling according to the present invention. The received information, class A rumor 890, is shown in the graph. At this time, it is searched by the address information 891 of the date and time when the rumor occurred. The search information was visualized at a location that corresponds to the date and time on the graph's time base.

In this case, all input conditions such as automatic buy / sell conditions, reference data, and separation degree conditions for reference data may be updated by the linked information. As an example of being updated in conjunction, if the user assumes that the reference data of the separation degree is linked with the evaluation of an analyst of 50,000 won, the sale is held up to 48,900 won.

As another example, if a securities firm and an analyst enter information such as 'Including all separation conditions and setting 10 times the separation distance' in the separation condition for the base date, the actual value of the separation degree is within '-7%'. (877) The input condition 876 in units of won and% is updated to 'within -70%' and automatically sold. This prevents the loss of users' assets in news that causes stock price drops.

8 illustrates a prediction stock graph 807 in conjunction with a conventional stock forecast graph service company computer system 801. As an input condition, the automatic purchase condition was set to 'concave pattern' at 10 minute rod and 'convex pattern' to 10 minute rod was set as selling condition. In addition, '(+) 1,000 won' was entered in the holding condition.

In addition, it is possible to input the separation degree for the stock price prediction graph linked to the reference data. In FIG. 8, it is determined that the condition of 'within 7% range' for the stock price prediction graph is satisfied. In other words, the stock price forecast graph is at the top of the actual graph at a distance of '7% or more' and becomes a buying condition.

In Figure 8, we first bought (810) for 27,000 won, which is the 'concave pattern' of the actual graph. In addition, the expected return of '1000 won' has been achieved and 'convex pattern' has occurred, resulting in selling (811), but the selling price has been exceeded by '7%' due to the expected return predicted by the stock forecast graph. Not sold by hold condition 872. And it was sold 812 at the second concave pattern of 32,000 won.

Meanwhile, the stock price forecast graph after 12 o'clock is expected to fall from 3,800 won to 27,500 won, while the stock bought (815) from 3,200 won is rising from 30,000 won to 3,500 won. It was. However, at this time, '7%' (877) is satisfied in the input condition of circle and% unit (876) of the separation degree to the stock price prediction graph to generate an automatic sell order.

At this time, the stock will be held until the convex pattern occurs if a graph rising from the stock price forecast graph to 24,000 won before 2 o'clock is entered. If the actual graph rises with a steep slope, the automatic trading system searches the account database for input conditions for additional buying conditions.

9 is an example of a pattern used as an input condition. First, conventionally used patterns 901, 902, 903, 904, 905, 906, and 907 are illustrated. At this time, the automated trading system searches for data using logic languages corresponding to the patterns. These input conditions can be stored in the account database by the user to download the pattern using a wired or wireless communication network.

The trend pattern 908 of FIG. 9 is a pattern that can be identified using an existing logic language. At this time, the present invention was identified using the existing pattern recognition technology. In addition, the pattern 909 is a convex pattern and a concave pattern divided by known pattern recognition techniques.

In the trend pattern, the area of the illustrated bar graph is used to identify the upward trend when the size becomes large. Searching the data pattern by various algorithms is a fact known to those skilled in the art, and thus detailed description thereof will be omitted.

Using this conventional system trading algorithm and well-known pattern recognition technology, item-specific data pattern readers identify patterns in which data is visible.

10 is a block diagram of a logic language automatic translation table and system. When the user enters a natural language in the automatic translation table, the mechanical translator automatically translates to the logic language.

In addition, the similar sentence search and presenter shown in FIG. 10 with respect to the input word suggests a similar sentence using the input word by searching the dictionary database and the similar sentence database. At this time, the user completes the natural language input by changing the presented sentence mainly by clicking on the letters constituting the condition with the mouse or directly changing the letters.

In FIG. 10, the use of the morpheme analyzer enables the conversion of a word, so that a logic language can be executed even when an input error or a variety of words are input. For example, even if you input the input conditions of various types of dialects and typos in natural language input, it is automatically translated.

Ultimately, the present invention integrates the example translation database and machine translation technology established through the collection of example data on input conditions in the sale and sale of securities, so that the user can buy and sell the securities without knowledge of logic language. I would like to.

As an example, when the user moves the mouse to point to 'buy' in the similar example of FIG. 10, the letters 'buy' and 'sell' appear and are selected by the mouse. This makes it easy to input by the method of word substitution.

The logic language that is the result of the translation is generated in the output field. Thus, when the user inputs a familiar natural language, the present invention converts the language into the logic language of system trading with the help of the translation technology used for the translation between the existing languages and the inter-language translation in the Internet chat.

In the example sentence database of the present invention, a sentence that can be input by the user is constructed as a database, and thus the example sentence is automatically recognized even in a dialect and a typo input in a natural language input. For example, natural language inputs that include dialects such as' lion ',' buy ',' current 10% higher buy ', '10% higher than current price', etc. It is stored so that the logic language of the system trading is displayed in the output field without error.

Since the translation technology of the logic language for system trading, which is an idea of the present invention, can be realized using a translation technology between languages and a publicly known technology used for chatting on the Internet, detailed description thereof will be omitted.

As described above, by providing the automatic translator in the present invention, a service for inputting a logic language through natural language input is provided.

Searching for stocks using a broader trading strategy is provided using information from various information sources as input conditions.

In addition, the automated trading system is provided for the use of input conditions using automatic trading and extended trading strategies for the retrieved items. In this case, additional buy and stop loss functions are provided using the extended trading strategy even when the separation of the reference data is changed. At the same time, automated trading methods are provided that identify actual patterns of change in data to maximize profits. In addition, a trade holding service is provided that suspends trading signals frequently generated by deception.

As another effect according to the system of the present invention, the user inputs the interlocking conditions to provide the service of holding and updating the input conditions by the input information such as war news, so that the market-adaptive trading strategy can be used. do.
