PURPOSE:To reduce the processing quantity of the title system by using a matrix-like table which correlates a flag which indicates whether or not a stage change takes place in one of objects with flags which indicate the state change of each object. CONSTITUTION:The market price information reported from a market 1 is received by means of a central processor 2 which carries out various calculation in accordance with the received information and displays the calculated results through terminal equipment 5 and 6. The time series data of the market price and the information of portfolios are stored in a data base 3. In a state managing table 4 brand names, current price sum changing flags, and guaranteed current price sum for checking the current price sum and states of the portfolios are arranged in the direction of the line. Each portfolio, price change flags, and current price are arranged in the direction of the row. A vector processor 7 is for calculating the current price sum at a high speed since the current price sum can be obtained by the inner product calculation of the portfolio row and current price. |
