A computer implemented trading system is described comprising a plurality of buy computers (1,2) connected via a communications network (3) to a plurality of seller computers (4,5), a plurality of public exchange computers (6,7) and a trading platform computer (8). The trading platform computer (8) is arranged to receive order data from the buy computers (1,2) and the seller computers (4,5). An order processing system (14) provided on the trading platform computer (8) processes the received data to generate output data indicative of the orders received by the order processing system (14) but which is processed so as to obscure the detail of received orders by calculating proximity between one or more actual orders in combination with randomised numbers. The generated data is then dispatched back to the buyer computers (1,2) and seller computers (4,5) where it is displayed as part of a user interface. By generating data indicative of the content of received orders but which obscures the detail of those orders, users are provided with information about the likelihood of an order entered into the order processing system (14) being matched but are prevented from using the received data to manipulate order prices.
