You can subscribe for update events as follows before calling the Start()<\/a> method.<\/p>\n\n\n\n

\/\/ Create a TradeSubscription to listen for update events\nm_ts = new TradeSubscription(t_net_sdk.Dispatcher.Current);\nm_ts.OrderAdded += new EventHandler<OrderAddedEventArgs>(m_ts_OrderAdded);\nm_ts.OrderDeleted += new EventHandler<OrderDeletedEventArgs>(m_ts_OrderDeleted);\nm_ts.OrderFilled += new EventHandler<OrderFilledEventArgs>(m_ts_OrderFilled);\nm_ts.OrderRejected += new EventHandler<OrderRejectedEventArgs>(m_ts_OrderRejected);\nm_ts.OrderUpdated += new EventHandler<OrderUpdatedEventArgs>(m_ts_OrderUpdated);\nm_ts.OrderStatusUnknown += new EventHandler<OrderStatusUnknownEventArgs>(m_ts_OrderStatusUnknown);\nm_ts.OrderTimeout += new EventHandler<OrderTimeoutEventArgs>(m_ts_OrderTimeout);\nm_ts.Start();\n<\/code><\/pre>\n\n\n\n
