The present invention relates to an electronic device, and more particularly to an electronic device for prompting a key price of a financial commodity.

As the standard of living of Chinese people is getting higher and higher, investment and financial management are receiving more and more attention. Index futures are a derivative financial instrument. Among the index futures traders, arbitrageurs lock in profits and costs by buying and selling index futures, and reduce the risk of price fluctuations caused by time. Investors take more risks through index futures trading and wait for opportunities to make profits from price fluctuations.

For traders who want to make a profit in the index futures trading market, it is not only reading the futures price trend chart to understand the time and price trend, but also referring to a variety of financial transaction information that may affect the futures price trend. Generally speaking, investors will subjectively decide the direction of investment based on the past performance of the futures trading market and the rules of experience of users. In other words, investors often cannot objectively and digitally judge the trend of the investment market. Such investment methods may bring high risks and high costs to investors. Therefore, users can use one of the index futures trading markets. These key prices are used to assist investment decisions, and the above key prices are generated through objective analysis of price and volume transaction statistics. In the past, investors often need to manipulate electronic devices to switch multiple operation screens to obtain differently defined key prices, which is very inconvenient to operate. In addition, if investors lose their attention or cannot focus on the market, for the rapidly changing investment market, investors cannot know immediately that the current real-time prices have exceeded or fallen these key prices, which will cause investors to miss a great investment. The timing or the timing of stop loss directly affects investment profits.

In view of this, the present invention proposes an electronic device for prompting key prices of financial commodities, which can display key prices with various types of definitions on an interface displaying various prices of financial commodities, so that investors can perform correct investment decision making.

The invention provides an electronic device for prompting key prices of financial commodities, which includes a network module, a display device, and a processing unit. The network module is connected to the network, and the display device displays a user interface. The processing unit is coupled to the network module and the display device. The processing unit is configured to: on the trading day of the financial commodity, read a plurality of historical key prices of the financial commodity before the trading day, wherein the historical key price is based on the historical price and volume transaction information of the financial commodity before the trading day. Generated; during the open trading period on the trading day, analyzing the current price and volume transaction information of the financial commodity to calculate multiple key prices today; and controlling the display device to display the historical key price and the key price today via the user interface .

Based on the above, in the embodiment of the present invention, the electronic device can respectively mark the historical key price and the current key price on a user operation interface providing different investment analysis information. In this way, the electronic device of the present invention can assist investors in performing correct investment decisions during investment operations.

In addition, the following description will continue to take a user's investment operation using an application in the electronic device 100 as an example on a trading day of futures commodities.

First, in step S201, on the trading day of the financial commodity, the processing unit 130 reads a plurality of historical key prices of the financial commodity before the trading day. Further, the processing unit 130 may read the stored multiple historical key prices from the storage module 132, or read the multiple history of futures commodities before the trading day from the analysis server 200 via the network module 110. Key price. The historical key price is generated by the analysis server 200 or the electronic device 100 based on the historical price and volume transaction information of the financial commodity before the trading day. Based on different historical key price definitions, the above historical key prices may include yesterday's highest price, yesterday's lowest price, this week's highest price, this week's lowest price, this week's opening price, this month's opening price, yesterday's average price, and multi-day interval One or a combination of average prices. Yesterday's highest price represents the highest transaction price of the financial commodity on the previous trading day, and yesterday's lowest price represents the lowest transaction price of the financial commodity on the previous trading day. This week's highest price represents the highest transaction price of the financial commodity in the week of the trading day, and this week's lowest price represents the The lowest transaction price of financial commodities during the week of the trading day. The opening price of this week represents the opening price of the financial commodity on the first trading day of the week of the trading day, and the opening price of this month represents the opening price of the financial commodity on the first trading day of the trading day. Yesterday's average price represents the average value of all transaction prices of the financial commodity in the previous trading day, while the multi-day interval average price represents all transactions of the financial commodity in the previous few trading days (such as the first three days, the first five days, etc.) The average price.

Next, in step S202, during the open trading period on the trading day, the processing unit 130 analyzes the current price and volume transaction information of financial commodities to calculate multiple key prices today. Specifically, the processing unit 130 may continuously receive the analysis chart information of the financial commodity provided by the analysis server 200 before the market close (open trading period) after the market opening. The above analysis chart information may include current price and volume transaction information of the financial commodity. Alternatively, the processing unit 130 may directly receive current price and volume transaction information of financial commodities from the analysis server 200 or the transaction server 300. The current price and volume transaction information includes the transaction price (including the entrusted buying price and the entrusted selling price), the entrusted buying quantity and the entrusted selling quantity at various time points on the trading day. Based on different definitions of today's key price, the above-mentioned key price today includes at least one of today's target price, today's highest price, today's lowest price, today's opening price, or a combination thereof. Today's highest price represents the highest transaction price on the trading day, and today's lowest price represents the lowest transaction price on the trading day.

Price and today's lowest price calculate today's support price and today's pressure price. For example, the processing unit 130 can calculate today's support price and today's pressure price according to the following formulas (1) and (2).

Today low + (now high-today low) * 0.618 = Today's pressure price Formula (1)

Today low + (now high-today low) * 0.382 = today's support price Formula (2) Among them, "today low" represents today's lowest price, and "today high" represents today's highest price.

After that, in step S203, the processing unit 130 controls the display device 120 to mark the historical key price and the current key price on the user operation interface. Further, in order to allow the user to quickly understand the difference between the real-time price of the financial commodity and the key price (including the historical key price and today's key price), the processing unit 130 can control the display device 120 to display the numbers marked with these key prices. line graph. In addition, when the processing unit 130 controls the display device 120 to display multiple prices related to financial commodities through a user interface (for example, the futures commodity can be commissioned to buy / sell within the limit of today's rise and fall (such as: ± 10%) Price, etc.), the processing unit 130 may mark the key price name next to the price equal to the key price.

It is worth mentioning that, in addition to directly marking the historical key price and today's key price on the user interface, in an embodiment of the present invention, the electronic device 100 can further determine whether the real-time price of the financial commodity approaches these historical key prices and Today's key price to decide whether to issue a warning alert user. Specifically, the input device 150 is coupled to the processing unit 130 and receives a user operation applied in the alert setting window. FIG. 3 is a schematic diagram of a warning setting window according to an embodiment of the present invention. Referring to FIG. 3, the display device 120 displays a setting field 31 through the warning setting window 30, and The user operates the setting field 31 to input the prompt value ‘2’. Based on this, during the open trading period of the financial commodity, the processing unit 130 can determine whether the absolute difference between the instant price of the financial commodity and the historical key price or today's key price is less than or equal to the suggested value. When the absolute difference between the instant price and the historical key price or today's key price is less than or equal to the prompt value, the processing unit 130 controls the alert prompt device 150 to issue an alert. Taking FIG. 3 as an example, when the absolute difference between the real-time price and today's highest price is less than or equal to '2', the processing unit 130 may control the alert prompting device 150 to generate a voice message of "near key price" to prompt the user. Alternatively, the processing unit 130 may control the display device 120 to display a text warning message, which is not limited in the present invention.
