Abstract: A processing method for securities information, which is employed in a user device of a securities information processing system, allows a user to execute a securities suggesting setting function in order to configure at least one securities suggesting condition composed of at least one candlesticks checking condition. When the user device receives a plurality of securities information, these securities information are checked to see if any of them fulfills all of the candlesticks checking conditions contained in any of the securities suggesting conditions. If the result is positive, then the user device suggests and prompts the fulfilled securities information to the user so as to provide a reference to the user for determining when to buy or sell the securities in which the user is interested.
