A electronic dealing system (EDS), implemented on a general purpose computer used in processing transactions, establishes, manages and updates values of credit lines not only between individual customers but also between groups of customers or between one customer and one group of other customers. Plural customers can be assembled as a subject, or home, group for whom a common credit line is set relative to other customers or customer groups; further, an individual customer or individual group of customers can assemble other, plural customers as an object, or opposing, group and for whom a common credit line is set. A subject or home group may set a common credit line value relative to an individual object, or opposing, customer or group of customers and, in transaction matching processing in relation to a customer of the home group, a credit line check is performed using the common credit line value of the home group in establishing a transaction with an opposing customer or customer group and the established amount of the transaction is subtracted from the common credit line value of the home group. |
