Abstract: PURPOSE: A method for reducing data when the stock trading information is inquired through the network is provided to save a server disk space storing the trading data, reduce a communication load without transmitting the unnecessary price data, and overcome the slowness of a screen by largely reducing a screen display time. CONSTITUTION: A server system receives a contracted stock trading data string including the data of time, a contracted price/volume, and a trading volume from a trade contracting system(S202). The server system compares the contracted price of a previously received data string with the contracted price of the data string(S208). In case that the compared prices are identical, the server system generates a temporary reduced data string by temporarily reducing the data strings into one string based on the contracted price(S210). If the compared prices are different with each other, the server system stores the temporarily reduced data in the disk and transmits the data to a client system(S216). If the server system receives the next data string, a process is returned to the first step(S212).
