As described above, the conventional scheme for generating an order for a target object has disadvantages in that: the ordering operation is complicated, time-consuming and easy to miss the ordering time, and the trader is difficult to accurately select the ordering price.
To address, at least in part, one or more of the above issues and other potential issues, an example embodiment of the present disclosure proposes a scheme for generating an order for a target object. In the scheme of the disclosure, each display unit of the first indication column is used for respectively presenting corresponding price indication data and determining position information of a plurality of display units which present the transaction price, the transaction quantity of the first attribute and the transaction quantity of the second attribute of the current sampling period in real time, and the presentation information of the display units of the indication column of the disclosure can be rapidly adjusted along with the current transaction price data and the market change in real time. In addition, the method ensures that the first indication column keeps the price indication data presented in the sampling period at the starting moment of cursor stay when the mouse cursor is positioned in the area of the indication column, namely the price indication data presented in the first indication column is locked, thereby avoiding the problem that the price to be placed is not easy to be selected by a user due to the rapidly-jumping market change data. Furthermore, the order is automatically generated and sent through the target price and the target transaction attribute determined based on the abscissa and the ordinate of the click operation, so that convenience and intellectualization of order placement can be remarkably improved. Therefore, the method and the system can conveniently show real-time rapid changes of the target object market, and ensure that a trader automatically generates an order based on the accurately selected price without complicated manual operation.

In some embodiments, the computing device 110 may have one or more processing units, including special purpose processing units such as image processing units GPU, field programmable gate arrays FPGA, and application specific integrated circuits ASIC, and general purpose processing units such as central processing units CPU.
A method 200 for generating an order for a target object according to an embodiment of the present disclosure will be described below in conjunction with fig. 2 and 3. Fig. 2 shows a flow diagram of a method 200 for generating an order for a target object according to an embodiment of the present disclosure. Fig. 3 shows a schematic diagram of an indication column according to an embodiment of the present disclosure it should be understood that the method 200 may be performed, for example, at the electronic device 800 depicted in fig. 8. May also be executed at the computing device 110 depicted in fig. 1. It should be understood that method 200 may also include additional acts not shown and/or may omit acts shown, as the scope of the disclosure is not limited in this respect.
At step 202, the computing device 110 obtains transaction price data for the target object for the current sampling period, the transaction price data indicating at least transaction price data, unit change price data, transaction identification data, and a transaction price and a transaction quantity associated with the transaction identification data for the current sampling period, the transaction identification data indicating at least transaction attributes, the transaction attributes including a first attribute and a second attribute.
With respect to the target object, it is, for example and without limitation, stock, futures, and the like. The unit price change data is, for example, a minimum price change of the contract.
With respect to the sampling period, the computing device 110 samples the trading price data of the target object twice, for example, and without limitation, in 1 second.
Regarding the transaction attributes, it includes, for example, a first attribute, a second attribute, and a third attribute. The first attribute is, for example, sell. The second attribute is, for example, buy. The third attribute is, for example, a drop order.
With respect to the transaction identification data, it indicates, for example, at least a transaction attribute, a transaction identification, a transaction price associated with the transaction identification, and a transaction quantity. The transaction identifiers include, for example, "buy one" (which indicates the buyer's order with the highest bid price), "sell one" (which indicates the buyer's order with the lowest bid price), "buy two" (which indicates the buyer's order with the highest bid price), "sell two" (which indicates the buyer's order with the lowest bid price), and so on, such as buy five, sell five. Taking the transaction identifier "buy one" as an example, the transaction price and transaction amount associated with the transaction identifier "buy one" are, for example, the requested buy price and requested number of the buyer's request with the highest buy price.
At step 204, the computing device 110 determines display window size data for the computing device.
Methods related to determining display window size data for a computing device may include a variety of, for example: acquiring the size of a display window through a GetClientRect (LPRECT lpRect) function; then, acquiring and calculating the position of the clickable area through interface layout; the position of each display element is then calculated by the row height of the display element and the column width (or column-indicating) size of the display element.
It should be understood that the aforementioned lplect represents a pointer that points to a rectangle structure of the RECT type. The rectangle structure is configured with four fields of left, top, right and bottom, which can be set to the size of the window. For example, the client coordinates CWnd of the workspace are copied into the structure pointed to by lpreg. The parameter LPRECT in the void GetClientRect (LPRECT) const points to the RECT structure or the feature object to receive the client coordinates. The left, top field is 0. The right and bottom fields indicate the width and height of the window. Wherein the client coordinates specify the top left corner and the bottom right corner of the workspace. Since the client coordinates are relative to the upper left corner of the workspace, the coordinates in the upper left corner are, for example, (CWnd 0, 0).
At step 206, the computing device 110 determines the number and location information of display elements included in a plurality of indicator columns based on the predetermined size setting, the price per unit change data, and the display window size data, each display element of a first indicator column of the plurality of indicator columns for presenting the corresponding price indicator data, respectively.
As for the plurality of indication columns, as shown in fig. 3, it includes, for example, a first indication column 310 for presenting price indication data, a second indication column 320 for presenting entrusting information for selling a target object, a third indication column 330 for presenting entrusting information for buying a target object, and a fourth indication column 340 for presenting entrusting information that a user does not make a deal. Each indication column includes a plurality of display cells. For example, the second indicator column 320 presents the quantity of orders "sell one" 324 to "sell five" 322, and the third indicator column 330 presents the quantity of orders "buy one" 332 to "buy five" 334. The corresponding price indication data for the same row of corresponding display elements "sell one" 324 through "sell five" 322 reflect the consigned prices "sell one" 324 through "sell five" 322. For example, the commission price for "sell one" 324 is 5118.
As for the predetermined size setting value, it is, for example, the height of each display unit row or the height of each display unit. The height of each display element is, for example and without limitation, 0.2.
The method of determining the number of display units and the position information included in each indication column includes, for example: determining the number of rows of display units based on the height of each row of display units and the display window size data; determining position information of the number of the display units in each indication column based on the number of rows of the display units; associating the transaction price of the current sampling period with the row of the display unit at the longitudinally central position of the screen to serve as price indication data corresponding to the display unit at the central position; and determining corresponding price indicating data of each display unit in the first indicating column based on the price indicating data corresponding to the display unit at the longitudinally-centered position, the unit change price data and the distance between each display unit in the first indicating column and the longitudinally-centered position. For example, the display unit 312 at the longitudinally centered position of the first indication column 310 presents a trade price of 5117 for the current sampling period, and the corresponding price indication data of each display unit above the longitudinally centered position is incremented by unit change price data (e.g., 1) one by one; the price indicating data corresponding to each display unit below the center position is decremented by unit change price data (for example, 1) one by one to finally determine the price indicating data corresponding to each display unit in the first indication column 310.
At step 208, the computing device 110 determines location information of a plurality of display units for presenting the transaction price, the transaction amount of the first attribute, and the transaction amount of the second attribute of the current sampling period in real time, respectively, based on at least the transaction price data of the current sampling period, the price indication data corresponding to each display unit, and the transaction identification data. By adopting the means, the display information of the display units of the indication columns is quickly adjusted along with the market change, so that the real-time change of the market of the target object can be better shown. In some embodiments, the color of the display units that are greater than or equal to the "sell one" transaction price are filled to a first color, such as a deep red color; the color of the display elements that are less than the "sell one" transaction price are filled with a second color, such as a light red color. For example, the computing device 110 compares the transaction price data for the current sampling period to the price indicating data corresponding to each display unit in the first indication column 310 to present the transaction price for the current sampling period at the display unit associated with the corresponding price indicating data equal to the transaction price for the current sampling period. The computing device 110 may also compare the transaction price associated with the transaction identification data of the first attribute with price indicating data corresponding to each display element in the first indication column; the transaction price associated with the transaction identifying data of the first attribute is determined to be equal to the display unit associated with the price indicating data so that the transaction amount of the first attribute is presented at the display unit in the second indication column 330 that is in the same row as the determined display unit. The computing device 110 may also compare the transaction price associated with the transaction identification data of the second attribute with price indicating data corresponding to each display unit in the first indication column; the display unit associated with the corresponding price indicating data equal to the transaction price associated with the transaction identifying data of the second attribute is determined so as to present the transaction amount of the second attribute at the display unit in the second indication column in the same row as the determined display unit.
For another example, if the computing device 110 determines that the centering mode is set, the display unit at the centered position of the first indication column is determined as the position of the first display unit for presenting the current transaction price in real time, so as to render the price indication data corresponding to the first display unit; and updating price indication data corresponding to other display units in the first indication column based on the price indication data corresponding to the first display unit and the unit price change data.
At step 210, the computing device 110 determines whether the cursor position of stay is within the display area of the indication column. For example, computing device 110 captures mouse cursor position information based on windows API techniques, and if computing device 110 determines that the cursor location is not within the display area of the indicator column, step 218 is skipped.
At step 212, if the computing device 110 determines that the cursor hover position is within the display area of the indicator column, each display element of the first indicator column is caused to hold price indicator data presented for the sampling period at which the cursor hover begins. For example, if the computing device 110 determines that the cursor stays within the display area of the indication column based on the abscissa and ordinate of the cursor stay, the sampling period at which the cursor stays at the start time is determined as the operation period, so that the displayed content of each display unit of the first indication column 310 no longer changes with the change of the transaction price data of the current sampling period collected in real time, but rather, each display unit of the first indication column presents the price indication data presented in the operation period. By adopting the means, even when the price of the target object fluctuates rapidly, when the mouse cursor is positioned in the indication area, the price indication data presented by the first indication column can be locked, so that the problem that the price to be placed is not easy to select by the user is solved. In some embodiments, the price indicating data of the first indicated column may be locked when the computing device 110 captures a mouse cursor position in any one of the three columns of the second indicated column (e.g., corresponding to the sell information indicated column), the third indicated column (e.g., corresponding to the buy information indicated column), and the fourth indicated column (e.g., corresponding to the cancel information indicated column).
In some embodiments, if the computing device 110 determines that the cursor position is not within the display area of the indicator column, each display element of the first indicator column 310 presents price indicator data generated based on the trading price data for the target object for the current sampling period. By adopting the above means, when it is determined that the user has no operation intention, the presentation information of the display unit of the indication column can be quickly adjusted to follow the market change again.
At step 214, the computing device 110 determines whether a click operation within the display area for the second column of indications or the third column of indications is detected. If the computing device 110 determines that no click operation has been detected for the display area of the second indicator column or the third indicator column, step 218 is skipped.
At step 216, if the computing device 110 determines that a click operation is detected for the display area of the second indicated column or the third indicated column, a target price and a target transaction attribute are determined, respectively, based on the abscissa and the ordinate at the click operation.
Regarding the method of determining the target price and the target transaction attribute, respectively, it includes, for example: determining a target trade attribute of the order as sold in response to determining that the abscissa at the click operation is between the first abscissa information and the second abscissa information of the second indication column; determining a target trade attribute of the order as buy in response to determining that the abscissa at the click operation is between the third abscissa information and the fourth abscissa information of the third indicated column; and determining price indication data corresponding to the display units with the same ordinate at the clicking operation so as to determine the target trading price of the order based on the price indication data corresponding to the display units with the same ordinate. The following will specifically describe the method for determining the target price and the target transaction attribute separately with reference to fig. 4, and will not be described herein again.
At step 218, the computing device 110 generates an order for the target object based on the determined target price and the target trade attributes to send the generated order to the control device. For example, the computing apparatus 110 generates an order of a sell target object with a sell price of 5124 to send to the management apparatus 130.
In the above scheme, each display unit of the first indication column is used for respectively presenting corresponding price indication data, and determining position information of a plurality of display units which present the transaction price, the transaction quantity of the first attribute and the transaction quantity of the second attribute of the current sampling period in real time, and the presentation information of the display units of the indication column of the present disclosure can be quickly adjusted along with the current transaction price data and the market situation change in real time. In addition, the method ensures that the first indication column keeps the price indication data presented in the sampling period at the starting moment of cursor stay when the mouse cursor is positioned in the area of the indication column, namely the price indication data presented in the first indication column is locked, thereby avoiding the problem that the price to be placed is not easy to be selected by a user due to the rapidly-jumping market change data. Furthermore, the order is automatically generated and sent through the target price and the target transaction attribute determined based on the abscissa and the ordinate of the click operation, so that convenience and intellectualization of order placement can be remarkably improved. Therefore, the method and the system can conveniently show real-time rapid changes of the target object market, and ensure that a trader automatically generates an order based on the accurately selected price without complicated manual operation.
In some embodiments, the method 200 further comprises: if the computing device 110 determines that the centering mode is not set, based on the current transaction price data and the price indicating data corresponding to the display unit, determining a position of a first display unit for presenting the current transaction price in real time so as to render the price indicating data corresponding to the first display unit; and determining position information of a first display unit group used for presenting a plurality of transaction quantities of the first attribute in the second indication column based on the transaction attribute and the transaction price associated with the transaction identification data and price indication data corresponding to the display unit; and determining a location of a second set of display elements for presenting the plurality of transaction quantities for the second attribute in the third indication column.
In some embodiments, the method 200 further comprises: if the computing device 110 determines that any of the following is satisfied, causing the display unit at the first indicated column-centered position to present the current transaction price data: the current transaction price is less than the price indicating data corresponding to the display unit at the lowest position of the first indicating column; the current transaction price is larger than the price indicating data corresponding to the display unit at the highest position of the first indicating column; and determining that the centering mode is set. A method 400 for determining a target price and a target transaction attribute, respectively, according to an embodiment of the present disclosure will be described below in conjunction with fig. 3 and 4. Fig. 4 shows a flow diagram of a method 400 for determining a target price and a target transaction attribute, respectively, according to an embodiment of the present disclosure. It should be understood that the method 400 may be performed, for example, at the electronic device 800 depicted in fig. 8. May also be executed at the computing device 110 depicted in fig. 1. It should be understood that method 400 may also include additional acts not shown and/or may omit acts shown, as the scope of the disclosure is not limited in this respect.
At step 402, if the computing device 110 determines that the abscissa at the click operation is between the first and second abscissa information of the second indication column, the target trade attribute of the order is determined to be sold. For example, the click operation is at the location indicated by the marker 326. The computing device 110 determines that the abscissa at the click operation is between the first abscissa information (i.e., the abscissa of the left-most edge of the second indication column) and the second abscissa information (i.e., the abscissa of the right-most edge of the second indication column) of the second indication column 320, then the target transaction attribute is determined to be sold.
At step 404, if the computing device 110 determines that the abscissa at the click operation is between the third abscissa information and the fourth abscissa information of the third indicated column, the target trade attribute of the order is determined to be a buy. For example, the click operation is at the location indicated by the marker 336, and the computing device 110 determines that the abscissa at the click operation is between the third abscissa information (i.e., the abscissa of the leftmost edge of the third indicated column 330) and the fourth abscissa information (i.e., the abscissa of the rightmost edge of the third indicated column 330) of the third indicated column 330, then the target trade attribute is determined to be a buy.
At step 406, the computing device 110 determines price indicating data corresponding to display units having the same ordinate at the click operation to determine a target trade price for the order based on the price indicating data corresponding to display units having the same ordinate.
A method 500 for adjusting indication column presentation information according to an embodiment of the present disclosure will be described below in conjunction with fig. 5. FIG. 5 shows a flow diagram of a method 500 for adjusting indication column presence information, in accordance with an embodiment of the present disclosure.

At step 502, computing device 110 obtains mouse wheel event data.
With respect to mouse wheel events, for example and without limitation, a mousewheel event or a domnousesscroll event.
At step 504, the computing device 110 determines a scroll direction and a scroll magnitude for a scroll operation of the mouse wheel based on the attribute information about the event object in the acquired mouse wheel event data.
For example, attribute information about an event object (e.g., event. wheeldelta) exists in a mousewheel event. The returned values for event. If the computing device 110 determines that the return value of the attribute information for the event object is a negative value, it determines that the wheel of the mouse is scrolling down. If the computing device 110 determines that the returned value of the attribute information for the event object is positive, it determines that the scroll wheel of the mouse is scrolling upward. The computing device 110 determines the scroll magnitude amplitude (i) based on the absolute value of the return value. The determination method of the scroll amplitude is described below with reference to formula (1).
In the above formula (1), amplitude (i) represents the scroll amplitude of the ith wheel event. | rvalue (i) | represents an absolute value of a return value of attribute information on the event object of the ith wheel event. K represents a coefficient.
At step 506, the computing device 110 determines price adjustment data based on the scroll magnitude.
Adjustmen(i)＝P*Amplitude(i) (2)
In equation (2) above, Adjustmen (i) represents the price adjustment data for the ith wheel event. P represents a coefficient indicating a correspondence between the scroll amplitude and the price adjustment data.
At step 508, the computing device 110 determines whether the scroll operation for the mouse wheel is scroll up.
At step 510, if the computing device 110 determines that the scroll operation for the mouse wheel is scrolling upward, the price indication data corresponding to each display element of the first indication column is incremented by the determined price adjustment data.
At step 512, if the computing device 110 determines that the scroll operation for the mouse wheel is not a scroll up, it determines whether the scroll operation for the mouse wheel is a scroll down.
At step 514, if the computing device 110 determines that the scrolling operation for the mouse wheel is scrolling down, the price indication data corresponding to each display element of the first indication column is reduced by the determined price adjustment data. For example, if the computing device 110 determines that the scroll direction for the scroll operation of the mouse wheel is scroll up and the adjustment data for the scroll magnitude is, for example, 3. Each display element of the first indicator column is subtracted by 3.
At step 516, the computing device 110 displays price indicating data after adjusting the data via increasing or decreasing price in a first indication column.
At step 518, the computing device 110 updates the location information for the first set of display elements for presenting the plurality of transaction quantities for the first attribute and the location of the second set of display elements for presenting the plurality of transaction quantities for the second attribute based on the price indication data after the adjustment data.

FIG. 6 shows a flow diagram of a method 600 for indicating a change in transaction price data, according to an embodiment of the present disclosure. It should be understood that the method 600 may be performed, for example, at the electronic device 800 depicted in fig. 8. May also be executed at the computing device 110 depicted in fig. 1. It should be understood that method 600 may also include additional acts not shown and/or may omit acts shown, as the scope of the disclosure is not limited in this respect.
At step 602, the computing device 110 determines whether the cursor position of stay is within the display area of the indication column.
At step 604, if the computing device 110 determines that the cursor position of stay is within the display area of the indicator column, the position of the first identification box is determined based on the transaction price data for the current sample period and the maintained price indicator data. For example, as shown in FIG. 3, the computing device 110 determines the location of the first identification box 314 based on the transaction price data for the current sampling period. If the transaction price data for the current sample period is 5117, the location of the first identification box 314 is as shown in fig. 3.
At step 606, the computing device 110 moves the first identification box over the first indicator column based on the determined location of the identification box such that movement of the identification box indicates a change in the transaction price data. For example, if the transaction price data of the current sampling period is 5118, the position of the first identification box 314 is moved up to the position corresponding to the price indication data 5118. By means of the method, when the price indication data presented in the first indication row are locked, the change of the transaction price data can be still indicated through movement of the indication frame, and therefore the trader can be guaranteed to automatically generate an order based on the accurately selected price, and real-time change of the market quotation can be conveniently and conveniently displayed.

It should be understood that method 700 may also include additional acts not shown and/or may omit acts shown, as the scope of the present disclosure is not limited in this respect.
At step 702, if the computing device 110 determines that the abscissa at the click operation is between the fifth and sixth abscissa information of the fourth indication column 340, the target trade attribute of the order is determined to be reversal. For example, the click operation is at the location indicated by the marker 342, the computing device 110 determines that the abscissa at the click operation is between the fifth abscissa information (i.e., the abscissa of the leftmost edge of the fourth indicated column 340) and the sixth abscissa information (i.e., the abscissa of the rightmost edge of the fourth indicated column 340) of the fourth indicated column 340, and then determines that the target transaction attribute is undo.
At step 704, the computing device 110 obtains the transaction amount associated with the display unit on which the click operation is located and the price indication data corresponding to the display unit corresponding to the first indication column. For example, computing device 110 determines that the transaction amount associated with click action 342 is said to be 200 strokes and the corresponding price indication data is 5109.
At step 706, the computing device 110 generates a target committed order for revoking the target object, the target committed order having the obtained price indicating data as the target trading price and indicating the obtained trading quantity. For example, computing device 110 withdraws the delegated order of 200 pens at the 5109 delegated price.
By adopting the means, the method and the device can conveniently withdraw the entrusted order.
