A stocks' dealing order representation method in an online dealings in stocks}

The present invention relates to a method for displaying an expected trading balance in an online stock trading, and in particular, by displaying the expected trading balance for a user's trading order for a particular item, thereby facilitating the stock trading situation after the trading order. The present invention relates to a method for calculating the expected remaining amount of a trading order in an online securities transaction.

As shown in FIG. 1, the online stock trading system in the related art including stocks and bonds that are currently widely serviced, the securities company server 3 connected to the stock exchange server 4 through the communication network (2) securities Receiving stock market information from the exchange server 4, and generating and accessing stock investment information such as indicators for each item or total stock market using various stock information analysis techniques, trends of price changes for each item, and the likelihood of investment profits. By transmitting to the user terminal (1) of the user, the user can establish a trading strategy, such as timely, sell price and quantity of securities trading, the user to the securities company server (3) through the communication network in accordance with this trading strategy When the securities trading request is made, the securities company server 3 is connected to the stock exchange server 4 and is configured to handle the processing of the trading according to the user's trading request. .

As a result, users who trade securities can perform securities transactions including stocks and bonds in real time without having to acquire specialized knowledge about securities, and waste time and effort of visiting securities companies. Therefore, users performing securities trading can use the high-quality information provided by securities companies for investment and perform stock trading in real time, thereby eliminating the problems of inconvenience and waste of stock trading.
