System for operating investment money

An investment money (IM) operating system comprising:

• an IM operation control module, while communicating with a client information processor connected to an online network, communicating with an IM management server that manages an investment of a client's IM in an investment product according to client setup information transmitted from the client information processor, and supporting an operation of IM;
• an IM operation simulation processing module, under the control of the IM operation control module, selecting a product invested at each turn and a product invested at a last turn from among investment products operated by the IM management server, according to the client setup information, generating an IM operation simulation data reflecting a total expected cash input demanded on the client, an expected cash output at each turn resulting from a purchase/operation of the product invested at each turn, the expected cash output at the last turn resulting from the purchase/operation of the product invested at the last turn, a purchase quantity of the product invested at each turn to match the expected cash output at each turn, and the purchase quantity of the product invested at the last turn to match the expected cash output at the last turn, by simulating in advance the selected product invested at each/last turn according to features of the products, and notifying the generated IM operation simulation data to the client information processor;
• and
• an IM operation execution module, under the control of the IM operation control module, transmitting the IM operation simulation data to the IM management server in response to client approval data for the IM operation simulation data to cause the product invested at each/last turn to be purchased and operated according to the purchase quantity of the product invested at each/last turn included in the IM operation simulation data and to cause the client to be paid the expected cash output at each turn and the expected cash output at the last turn at each turn and at the last turn, respectively.
