In this configuration, the FIX transport is designated as a server (acceptor) and targetCompIds are set up for each FIX client.

The FIX_OrderServer listens for FIX NewOrderSingle messages and forwards these onto the ScenarioOrderService which instantiates the specified scenario with the values from the order and listens for updates.

Once an order has been created and its scenario has been instantiated, it is possible for the client to modify or delete the order by sending the appropriate FIX messages.

The following sections discuss the FIX_OrderServer and the ScenarioOrderService in detail.
