23. The display format designating unit 120 includes the feature extracting unit 1
06 and the set value storage unit 108
The method for indicating the state of the price movement is selected based on the flag for specifying the method for indicating the state of the price movement supplied from the company.
When listing security information and comparing the state of price movements of multiple securities, the price range, which is the amount of price movement of the security, differs depending on the security brand, the type of security, etc., so the price movement depends on the price range. It is difficult to compare the state of the price movement simply by selecting the image indicating the state of. For example, if the state of price movement of a brand that moves in units of one yen and the price that moves in units of one hundred yen are shown on the same scale, the user cannot compare the state of price movement of each brand. For example, when the direction of the arrow is changed by changing the direction of the arrow by 10 degrees every 100 yen, the number of brands that change in the unit of one yen is 5
The direction of the arrow does not change even if the circle moves. Therefore, the display format specifying unit 120 specifies one of a method of indicating the state of the price movement of the security using a percentage and a method of indicating the state of the price movement of the security using the amount of the price movement as it is.

When the status of the price movement of the security is indicated by using a percentage, the display format specifying unit 120 may indicate the price width in percentage with the price immediately before updating the current value as 100. Further, the difference between the maximum value and the minimum value in a predetermined period in which the moving average is calculated may be expressed as a percentage with the difference between the maximum value and the minimum value as 100. In addition, the price range may be represented by a percentage, with the average value of the price movement as one hundred. When the price range is expressed in percentage, the securities information processing apparatus 100 stores the entire value used when calculating the percentage in the set value storage unit 10.
Read from 8. For example, when the price immediately before updating the current value is assumed to be 100, the securities information processing apparatus 100 reads the price immediately before updating the current value from the set value storage unit 108. When the image selection unit 122 sets the difference between the maximum value and the minimum value in the predetermined period in which the moving average is calculated to be 100, the securities information processing apparatus 100 calculates the moving average from the set value storage unit 108 The difference between the highest value and the lowest value during the period is read. In another embodiment, when the entire value is not stored in the set value storage unit 108, the securities information processing apparatus 100 stores the entire value in the network 16
May be read from either the head office host computer 12 or the branch host computer 14. By doing so, the amount of information stored in the setting value storage unit 108 can be reduced.

The image selection unit 122 includes a display format designation unit 12
Based on the information supplied from 0, an image indicating the state of the price movement is selected from the image storage unit 112 and added to the securities information. The advice information adding unit 123 adds the forcibly added advice information supplied from the advice information receiving unit 116 to the securities information. The information according to the state of the price movement is added to the securities information by the image selecting unit 122 and the advice information adding unit 123.

FIG. 6 is a flowchart of the securities information processing apparatus 100. The operation of the securities information processing apparatus 100 will be described with reference to FIGS. Securities information receiving section 1
02 receives the security information and outputs it to the feature extraction unit 106 (S10). The feature extracting unit 106 includes the securities information receiving unit 10
It is determined based on the set value stored in the set value storage unit 108 whether or not the security information supplied from 2 is a security designated to be displayed in advance. In the case of security information of a security not specified to be displayed, the security information processing device 1
00 ends the processing and waits until the next security information is supplied.

In the case of security information of a security designated to be displayed, the feature extracting unit 106 sets the setting value storing unit 108
Is calculated in the period stored in (S1)
4). For example, when it is set to calculate the price range from the previous day's closing price, the feature extracting unit 106 calculates the price range from the previous day's closing price. Further, for example, when it is set that the moving average in the short period, the moving average in the middle period, and the moving average in the long period are set as the previous day, 5 days, 8 days, and 30 days, respectively, the feature extraction unit 106
Calculates the moving average in each period. For example, the moving average may be an average value of the price of the security in each period. When displaying the value movement of the moving average, the feature extraction unit 106 calculates the value width between the current moving average and the immediately preceding moving average. The state of the price movement to be calculated is preferably calculated based on the price range of the price from the previous day or the price range of the moving average, and the period for calculating the moving average is preferably set by the user. If not set by the user, it is preferable to apply a default value. Further, the default value may be set according to the type of each security, or the set value stored in the head office host computer 12 or the branch host computer 14 via the network 16 may be read.

The display format designating section 120 includes the feature extracting section 10
Based on the price range calculated in step 6, it is designated whether the state of the price movement is displayed as it is, or the value range is expressed as a percentage (S16). It is preferable that the value is specified by the user. When the value is expressed as a percentage, the display format specification unit 120 reads the entire value of the percentage from the setting value storage unit 108 and indicates the value range in percentage. The image selection unit 122
The value width is associated with the image 154 indicating the state of the value movement (S18). For example, when the image storage unit 112 stores an image 154 indicating the state of the value movement indicating the state of the value movement in 10 steps, and displaying the image 154 indicating the state of the value movement based on the value indicating the value width in percentage, Image selection unit 1
An image 22 is associated with an image indicating the state of the price movement every 10%. More specifically, when the value indicating the value width as a percentage is 0 to 10%, the image is correlated so as to select the image 154 indicating the state of the first-level value movement. 10
In the case of from 20% to 20%, the image is displayed so as to select the image 154 indicating the state of the value movement in the second stage. In this way, the value width and the image 154 indicating the state of the value movement are associated with each other.

The image selecting unit 122 selects an image 154 indicating the state of the price movement associated with the price range by the display format specifying unit 120 based on the price range, and adds it to the securities information (S20). The advice information adding unit 123 determines whether the advice information to be forcibly displayed is supplied from the advice information receiving unit 116 (S22). If you have been given advice to force display,
The advice information adding unit 123 adds the advice information to the securities information (S24). The display control unit 114 causes the display device 118 to display the securities information to which the information selected based on the price range and supplied from the information adding unit 110 is added (S26). Therefore, the security information processing apparatus 100 can add additional information based on the price range of the security.

FIG. 7 shows an example of the set values stored in the set value storage section 108. This set value is stored in the feature extraction unit 106
The state of the value movement calculated in is set. The set value for setting the state of price movement holds a display flag for specifying whether or not to display, and a number of calculation days for specifying a period for calculating the price range, for each state of price movement to be calculated. For example, in the case of the set values shown in this figure, the price range between the previous day's close price and the current value, and the long-term moving average are not displayed on the display device 118 because the display flag specifies that the display is not to be displayed. The short-term moving average and the medium-term moving average are displayed on the display device 118 because the display flag specifies that they are to be displayed. Further, based on the set value, the feature extracting unit 106 calculates a 5-day moving average as a short-term moving average. Further, based on the set value, the feature extracting unit 106 calculates a moving average for eight days as a medium-term moving average. The set value for setting the state of price movement is preferably set for each security brand.
This set value may be arbitrarily set by the user, or may be supplied from the head office host computer 12 or the branch host computer 14 via the network 16.

FIG. 8 shows the closing price, short-term moving average and medium-term moving average on each day. The method of calculating the moving average will be described with reference to FIG. The set value storage unit 108 stores the final values (P1, P2, P3, P4,...). When the period for obtaining the short-term moving average is set to 5 days, the feature extracting unit 106 can calculate the short-term moving average As1 after storing the closing price P5. When the period for obtaining the medium-term moving average is set to 8 days, the feature extraction unit 106 stores the medium-term moving average Am after storing the closing price P8.
1 can be calculated. The moving average is the average value of the prices of securities for a predetermined period. For example, when the period for calculating the short-term moving average As is Ds, the short-term moving average As
Is As1 = (P1 + P2 + P3 + P4 + P5) ÷ Ds
Can be calculated. For example, when the period for calculating the medium-term moving average Am is Dm, the medium-term moving average Am is Am
= (P1 + P2 + P3 + P4 + P5 + P6 + P7 + P
8) It can be calculated by ΔDm.

A method of calculating the price range for the closing price, the short-term moving average price range, and the medium-term moving average price range when the closing price P9 is received will be described with reference to FIG. The price range for the closing price is calculated by subtracting the closing price P8 from the closing price P9.
The price range for the short-term moving average is calculated by subtracting the short-term moving average As4 from the short-term moving average As5. The price range for the medium-term moving average is from the medium-term moving average Am2 to the medium-term moving average A
It is calculated by subtracting m1. Also, in another embodiment, 19
The short-term moving average from July 1 to July 6, 1999 was
Head office host computer 12 via network 16
Alternatively, it may be read from the branch host computer 14. The medium-term moving average from July 1 to July 9, 1999 may be read from the head office host computer 12 or the branch host computer 14 via the network 16.

FIG. 9 is an example of an image 154 showing the state of the value movement stored in the image storage section 112. The image 154 showing the state of the price movement is preferably an image showing the state of the price movement stepwise. Image 1 showing the state of price movement
Reference numeral 54 may be an arrow, a triangle, or a character, and is stepwise as shown in this figure. For example, in the case of an arrow, the angle of the arrow changes stepwise. For example, in the case of a triangle, the size of the triangle changes stepwise. For example, in the case of a character, the expression of the character changes gradually. Image 154 showing the state of these price movements
Is preferably set arbitrarily according to the user's preference, and is preferably an image in which the state of the price movement is easily transmitted to the user. Further, in another embodiment, the color of the image 154 indicating the state of the value movement may change according to the state of the value movement. For example, when the price increases, the color of the image 154 indicating the state of the price movement may be blue, and when the price decreases, the color of the image 154 indicating the state of the price movement may be red. Further, when the prices are the same, the color of the image 154 indicating the state of the price movement may be black.

FIG. 10A shows an example in which the state of the price movement is indicated by color. For example, if the price of a newly received security is higher than the current value, an arrow may be displayed in blue. If the price of a newly received security is lower than the current value, an arrow may be displayed in red. If the current value is the same as the price of the newly received security, an arrow may be displayed in black.

FIG. 10B shows the state of the price movement by the arrow 15.
This is an example of a case indicated by 6 and a point 158 indicating the current value. In this example, the state of the price movement is indicated by an arrow 15.
This is an example shown by the positional relationship between 6 and point 158. For example,
Arrow 156 is above point 158 if the price of the newly received security is higher than the current value. If the price of the newly received security is lower than the current value, the arrow 156 indicates the point 1.
It is below 58. When the current value and the price of the newly received security are the same, the arrow 156 and the point 158 are at the same position.

Therefore, the securities information processing apparatus 100 can indicate the state of the price movement of the securities in an image that is easy for the user to understand based on the received securities information. Also, since a list can be displayed, a plurality of securities can be compared. Further, an image 1 showing a state of a price movement according to the price range.
