<p>[Problem] To provide a market transaction assistance device that can prevent losing the opportunity to profit in situations of a continuing trend, while suppressing the risk of loss to a minute level. [Solution] In the present invention, after a stop-limit order has executed for settling a held position, if it is determined that predetermined conditions are satisfied indicating that the market price has moved in a direction of increasing profit (direction of decreasing loss), a transaction is executed for holding a new position. As a result, even in situations where a stop-limit order could easily be executed with a comparatively small value for the price spread indicated by price spread information (3111), it is possible to hold a new position again and again as long as it is determined that the predetermined conditions are satisfied indicating that the market price is moving in the direction of increasing profit.</p> |
