Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the existing stock technical index display method, only one or a plurality of index data are usually fixedly displayed, and when a user needs to compare various stock technical index data according to own needs, the user usually has two modes: 1. and 2, configuring various technical indexes in two frames or three frames in the screen, and 2, comparing in a chart switching mode.
The handheld terminal is limited by the size of a mobile phone screen, only 2-3 technical indexes are usually displayed in one page, and 5 or more technical indexes can not be displayed simultaneously for comparative analysis of indexes as a PC. If a user needs to compare and analyze more than 3 technical indexes, the indexes are usually switched and checked respectively, so that the display time of the index data before and after switching cannot be synchronized in real time, and the real-time performance of stock data is very important.
In the prior art, several indexes are combined to be displayed in a chart, and the combination mode is a common comparison combination mode, such as two indexes of a K line and a volume of business, and two indexes of a K line and a 7-day average line. The user of the combination mode can not combine the indexes according to the needs of the user.
In the prior art, an index chart is usually switched by selecting one index list, and the switched index chart replaces the index chart before switching. After switching, the previous index chart is not displayed any more, so that the index charts before and after switching cannot be compared in real time.
The invention improves the efficiency of data acquisition, transmission and processing by technical means, overcomes the technical defects, realizes self-combination index drawing according to the requirements of users, and aims to eliminate poor user experience and improve the service quality.
The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Fig. 1 is a flow chart of a stock technical index display method for displaying a selected stock technical index, which, as an embodiment of the present invention, includes the following steps 101 to 103:
In step 101, the stock market basic data includes closing price, opening price, highest price, lowest price, volume of bargain and/or volume of bargain, and a group of primitive data includes time of an index and corresponding value; the stock market basic data can be provided by a market server, the primitive data can be obtained by modeling the stock market basic data according to a certain rule by a handheld terminal, and generally, all key information of an index is completely described by one primitive data model. Preferably, the stock market basic data is the data after the weight is removed.
In step 101, a stock market data request command sent by a handheld terminal or other devices includes: obtaining the information of stocks or indexes selected by a user, such as the upper syndrome index 000001; acquiring cycle information selected by a user, such as a 1 minute cycle, a 5 minute cycle, a day cycle and the like; acquiring the right removing information selected by the user, such as right removing, right returning and the like; the hand-held terminal transmits the information as a request instruction.
In step 101, the stock market basic data is received by the handheld terminal, and the market server obtains the request instruction sent by the handheld terminal and sends the market basic data to the handheld terminal. For example, the stock market basic data includes: daily opening price taking the daily cycle as an example, daily maximum price taking the daily cycle as an example, daily minimum price taking the daily cycle as an example, daily closing price taking the daily cycle as an example, daily volume taking the daily cycle as an example, and daily volume taking the daily cycle as an example.
In step 101, the market server provides basic data of stock market, which includes: the data source is the exchange, and the data of a plurality of exchanges is uniformly integrated into a data structure through a data server (market server) to uniformly form data pushing opportunity. The handheld terminal uses the basic data of the 'subscription' request, the 'subscribed' request is provided by the data server for data push once, and the data is pushed immediately after the real-time market change, so that the advantages are as follows: multiple exchange data are integrated, and push in a subscription mode is carried out.
After receiving the basic data, the handheld terminal carries out modeling according to a specified rule and converts the basic data into a plurality of specified groups of index data, and the index data have certain characteristics such as time and one or more numerical values. And (4) submitting the converted multiple groups of index data to a chart for graphic drawing and displaying to a user. The advantages are that: modeling can be carried out according to the selection of a terminal user, and a chart drawing graph is visually displayed.
In step 101, the handheld terminal performs modeling based on stock market basic data and configured index combinations to obtain multiple groups of primitive data.
Specifically, the handheld terminal device obtains the stock market basic data from the server, and simultaneously obtains the index combination selected by the user, such as a K line, a 3-day average line, a 10-day average line, an RSI and the like; and modeling the index data according to the stock market basic data and the selected index combination to obtain the primitive data of a plurality of indexes.
A group of primitive data comprises an index of time and corresponding values, specifically: and the time data comprises a timestamp describing time and at least one value attribute describing key information of the index, such as closing price, opening price, highest price, lowest price, volume of bargaining and/or volume of bargaining.
In step 101, different indexes describe different features of market data, and the configured index combination should be of a ruler type with the same unit, and the ruler type includes two types: stock prices and stock volume.
In step 101, modeling is performed according to stock market basic data and a plurality of selection indexes to obtain corresponding primitive data.
Specifically, the input of the model is the stock basic quotation data and a plurality of indexes selected by a user; the output of the model is primitive data comprising time and specific index values; the modeling process can adopt the existing index model building method, for example, each index should have its determined calculation rule, for example, the 7-day average line index is the average value of the closing prices of the current day and 6 days before the current day as the index value of the current day, and each index obtains a set of primitive data of the index through its determined calculation rule.
It should be noted that each index corresponds to a group of primitive data, each group of primitive data is a set of data items, and each data item includes timestamp information describing the index and data information describing a numerical value of the index. When multiple groups of primitive data are combined, the data items in each group are aligned according to the time stamps of the data items, and the graphs are aligned according to the time stamps on the graphs when the primitive data models of each group are displayed, so that the obtained multiple groups of primitive data models are aligned according to the time stamps, and the values of multiple index graphs in each longitudinal unit area on the graphs are all one time.
In step 101, data exchange between the handheld terminal and the market information server uses long connection based on TCP, and transmitted data uses a byte stream format, which greatly reduces occupation of network bandwidth compared with JSON/XML/ProtoBuf and other formats, thereby improving speed transmission speed, and enabling the handheld terminal to display index data more timely.
The data are requested from the market information server by the handheld terminal in a subscription mode by using a byte stream communication mode of basic TCP long connection, the handheld terminal immediately acquires the data of the market information server after subscription, and the market information server sends updated data to the handheld terminal when the market information data is updated; the handheld terminal immediately takes the data as the input of a data modeling process after obtaining the data, and the index drawing module finishes drawing the graph after modeling, and the processes form the complete process of the method.
The subscription type transmission mode based on the TCP ensures the timeliness of data; if the method is not suitable for the conventional request-response type HTTP transmission method, the handheld terminal requests data updating in a polling mode, so that the timeliness of the data cannot be guaranteed, network resources are wasted during the period of non-opening of the stock market, and additional resource overhead (CPU, memory, heating and the like) of the handheld terminal is caused.
In data acquisition, when data of an exchange changes, acquisition and recording are carried out immediately; in data transmission, a request for subscribing based on TCP long connection is used, and the changed data associated with the subscribed handheld terminal can immediately obtain updated data; in the data display process, each group of primitive data is respectively calculated and returned during modeling, and the situation that the data display is not in time caused by the increase of the number of configured indexes is avoided.
And 102, judging the type of the scale for the index unit of the primitive data, and drawing multiple groups of primitive data with the same type of the scale in one graph to obtain a plotted graph, wherein the abscissa of the plotted graph is time, and the ordinate is a scale value.
In step 102, the scale type of the index unit includes the stock price and the stock volume, i.e., the index map includes two types, one is a graph based on the stock price and the other is a graph based on the stock volume.
In step 102, the coordinate system X time axis and Y numerical axis of the plotting chart are calculated according to the primitive data, and the coordinate system and the network line are rendered.
The X axis is a time range, and a user can set a range of the displayed index data on the handheld terminal, namely a timestamp of the first piece of data and a timestamp of the last piece of data which need to be displayed, so as to obtain the X axis range of the index chart; and taking out key information data to be drawn according to the x-axis time range, and dividing the x-axis width range occupied by drawing each data in the chart.
The Y axis is a numerical range, all numerical attributes in the set range in the primitive data of the multiple indexes are taken out, the maximum value and the minimum value of the numerical values in the multiple indexes are calculated, and the Y axis range of the index chart is obtained; and according to the range of the y-axis value, converting the graph to draw the corresponding relation between the median and the coordinate point.
In order to facilitate a user to observe the index chart, the x axis is divided into a plurality of parts equally, time points are marked, and a dotted line mode is used as a grid line; the y-axis is divided into several halves, and the price or the quantity is identified and used as a network line in a dotted line mode.
In step 102, multiple groups of primitive data with the same ruler type are plotted in one graph to obtain a plotted graph, wherein different indexes can adopt a specific plotting mode or an optional plotting mode.
For example, the key information in the primitive data of the K line graph contains the opening price, the closing price, the highest price and the lowest price; the line graph comprises a description of a price or a volume in the key information in the graphic element data model; the key information in the graphic element data model of the histogram comprises a description of a price or a quantity; the energy graph comprises a description of an energy percentage of key information in a graphic primitive data model; the variable color line graph should contain a color change threshold in addition to key information in the line graph.
The plotting chart may include any one of the above-described drawing methods, or may include any combination of plural kinds of the above-described drawing methods.
The single index drawing method is realized by confirming a graph drawing method according to the index type, taking out key information data to be drawn according to an x-axis time range, dividing an x-axis width range occupied by each data in drawing in a chart, and converting the corresponding relation between a graph drawing median and a coordinate point according to a y-axis value range; and according to a graph drawing method, sequentially drawing the key information data from the left to the right of the x axis to finish drawing.
If the index mapping chart contains a plurality of indexes, units of key information described by the indexes need to be consistent, such as stock prices and stock volume.
In step 102, all indexes may be modeled and then drawn, or the index unit of each group of the primitive data may be immediately drawn after judging the type of the ruler.
When a user sets and displays a plurality of indexes, the modeling process can be used for modeling for each index, the process is serial, namely, each index is modeled in sequence, therefore, all indexes can be modeled and then graphically drawn, and a mode of returning for many times can be adopted, one index is modeled and then graphically drawn immediately, and then a second index is modeled.
And a mode of returning for multiple times is adopted, namely, after modeling of each index is completed, the modeling result is drawn, and the timeliness can be improved.
In step 102, the index plot drawing is a hierarchical structure, only the layer with data update is changed during drawing each time, and the index plot drawing comprises: the graph frame layer is used for displaying the coordinate axes of the graph; the plotting layer is used for displaying the numerical value of the graphic primitive data; the cross cursor layer is used for displaying the last or currently selected graphic element data; and the user interaction layer is used for receiving the operation interaction requirement.
The layered display structure drawn by the indexes can improve the refresh display efficiency of the index graph, and the indexes and other elements in the graph and interactive processing are processed in a layered mode to improve the refresh display efficiency.
It should be noted that the range of the graphic coordinate axis of the graphic frame layer can be set manually or according to the primitive data; the index plotting layer is used for plotting graphs of a plurality of indexes, the indexes with the same index unit scale are plotted in the same graph, and whether the indexes are plotted or not can be manually selected; the cross cursor layer is used for displaying the last or currently selected index data and displaying a cross cursor in the long-pressing process of the index graph; the user interaction layer: and the system is used for receiving the operation interaction of the user, such as moving the display area, enlarging and reducing the display range, long-pressing the cross cursor display and the like.
The advantage of this hierarchical rendering is that each rendering process does not necessarily require rendering for each layer, but only for layers that need to be redrawn.
In step 103, a data family is configured through the handheld terminal, and is used for binding the ruler types and the index types of the multiple groups of primitive data into a set, so as to facilitate data indexing.
The handheld terminal is configured into a data family, so that customized services can be provided for users conveniently. When a specific user uses a specific handheld terminal, the specific user usually pays attention to a specific data family with higher frequency and pays attention to other index data with lower frequency; when the generated plurality of first identification information correspond to a plurality of data families, the handheld terminal and the market server are convenient to exchange stock data corresponding to the concerned data family preferentially through the indication of the first identification information without globally updating the stock data, and the data transmission, storage and processing efficiency of the part of data family which is often concerned by the user is obviously improved.
It should be noted that, in step 101, the stock market data request command sent by the handheld terminal or other device may further include the first identification information and/or a data family definition corresponding to the first identification information. When the stock market data request command contains the first identification information, the requested data contains the corresponding stock market basic data, and preferably, the requested data is limited to the stock market basic data corresponding to the first identification information. When the stock market data request instruction contains the data family definition corresponding to the first identification information, the stock market data request instruction informs the market server, and the data family corresponds to the ruler types and the index types, so that the service configuration information of the handheld terminal is transferred to the market server.
It should be noted that the first identification information is also transmitted in real time by means of byte stream communication of the underlying TCP long connection. Therefore, the stock market data can be searched from the stock market data by the market server according to the received first identification information.
It should be noted that, when the drawing is performed in step 102, if the ruler type is determined for each group of index units of the primitive data, the drawing is performed immediately, and when the drawing is updated, the corresponding stock market basic data is transmitted according to the first identification information, so as to update the primitive data.
It should be noted that the above steps 101 to 103 do not limit the continuous relationship, and can be operated circularly.
The invention provides a stock technical index display method, which can be used for customizing display services on a handheld terminal or other terminal equipment, integrating market data of a plurality of transaction platforms into a unified structure in data acquisition, and acquiring and transmitting the data according to the requirements of the customized system services; in the data display process, market data with a unified structure is used as input of primitive data modeling, the modeling configuration information is from used configuration and comprises a plurality of index graphs which need to be drawn, each index graph comprises a plurality of indexes and configurable parameters of each index, and the index data modeling module performs modeling in a grading mode according to input market basic data and configuration information to obtain a plurality of groups of index primitive data; in the data display process, after index primitive data are obtained by modeling each time, the primitive data of the index graph are drawn, each group of primitive data is a combination of a plurality of graphs (such as broken lines, columns, filling lines and the like), and a combined graph of the technical index is obtained after drawing.
FIG. 2 is a flow chart of an embodiment of a stock index display method including second identification information,
In step 201, stock market data from different exchanges may be data-integrated by a market server.
Specifically, the market data of a plurality of exchanges (such as an exchange, a deep exchange and a new three-plate exchange) are integrated by the market server, the data differences of the exchanges are shielded by the market server, the integrated fields comprise opening price, closing price, lowest price, highest price, volume of bargain and the like, and simultaneously carry a data conversion digit, the handheld terminal only needs to perform division operation according to the digit field to obtain a correct display numerical value, the differences of data of different exchanges do not need to be processed, the complexity of processing the data by the handheld terminal is greatly reduced, and the efficiency of the handheld terminal on the scene is improved.
For example, the stock market data and the data conversion digit are received by the handheld terminal, and the stock market data is divided by the corresponding data conversion digit to obtain the stock market basic data.
By integrating the stock market data, the data of different formats and different transmission frequencies of different exchanges can be processed uniformly according to time and formats, so that the data of fixed format and transmission frequency can be obtained, the data volume is reduced, and the data processing efficiency is improved.
And 203, judging the type of the scale for the index unit of the primitive data, and drawing multiple groups of primitive data with the same type of the scale in one graph to obtain a plotted graph, wherein the abscissa of the plotted graph is time, and the ordinate is an index value.
In step 205, the first identification information is received by the market server, and the index type and the scale type of the data family are determined.
And step 206, selecting the stock market data from the stock market data according to the index type and the scale type of the data family, generating second identification information for the index type of the stock market data, and updating the stock market basic data.
In step 206, selecting the stock market data by the market server according to the index type and the scale type of the data group determined by the first identification information, generating second identification information for the index type of the changed data, updating the stock market basic data, and sending the updated stock market basic data to the handheld terminal.
