PROBLEM TO BE SOLVED: To output an alarm for order reviewing to a user or a player after ordering real or virtual stock trading and before contract. SOLUTION: When a stock trading order is received from a terminal 16, a stock transaction server 12 registers the order in an uncontracted order table. Contract data for specifying a contracted order are supplied to the server 12, and the server 12 deletes the contracted order from the uncontracted order table. The IDs of players, brand code, stock price at ordering and a limit are stored in the uncontracted order table while made to correspond to one another, and the server 12 notifies a player who has placed a limit order of an alarm to the effect that the difference between the current price and the limit is apart from the difference between a price at limiting and the limit by not less than a fixed value, in the form of e-mail with respect to the limit order that has not been contracted yet, when the difference between the current price and the limit exists in the above way. |
