In an automated exchange system means are provided by means of which a market maker can enter a course of action in advance, so that the volume in the orderbook is continuously updated, and where the updating is performed differently with respect to different counter parts. Also, quotes that may result in a trade between Market Makers are hidden for some time before being matched, thus giving the Market Makers a chance to back off. The system employs a function that supports that Market Makers through pre-defined parameters will have new orders generated by the system and that a market maker can act differently with respect to different counterparts. The parameters specify if a Market Maker should add extra volume on an existing price or generate a new order at a worse price. In order to make it possible for market makers to have a very tight spread without forcing them to take larger risks, additional logic is used when matching orders. The algorithm used for this purpose protects the market makers in certain situations and gives market makers the possibility to have a tight spread without taking a large risk. The algorithm also supports that the market makers can take the risk to quote large volumes.

In an automated exchange system, the deterministic matching is supplemented with a non-deterministic trade agent service. The agent server is preferably run in accordance with a best-effort principle, thereby making it possible to design at low cost. The agent trade server is designed to provide users with functionality deemed not to be necessary to implement in the deterministic core of the matching system or deemed to be to expensive to implement therein. The agent trade server then feeds the deterministic core of the matching system with trade input data resulting from the input received for the users of the automated trading system. Thus, the designer of a complex trading system is given an option to provide centrally located functionality to the users of the system without having to change the deterministic core of the matching system. Since the agent trade server is working closely to the deterministic core of the trading system, it is preferred to co-locate the agent trade server with the core of the matching system.
