Get options chain

[zairgit]

Is it possible to get a real time options chain on something like NDX?

here's the basics

            IBClient client = new IBClient();
            try
            {
                client.Connect("127.0.0.1", 4001, 2);
                client..ContractDetails += c_ContractDetails;

                Contract e = new Contract("MSFT", "SMART", SecurityType.Option, "USD");

                client.RequestContractDetails(1001, e);

                Console.WriteLine("Hit [Enter] to quit.");
                while(Console.ReadKey().Key != ConsoleKey.Enter)
                { System.Threading.Thread.Sleep(500); }
                Console.ReadLine();
            }
            finally
            {
                client.Disconnect();
            }

            ...

             void c_ContractDetails(object sender, ContractDetailsEventArgs e)
            {
            string desc = "Security Type Not Supported. See onContractDetails.";
            switch(e.ContractDetails.Summary.SecurityType)
            {
                case SecurityType.Option:
                    Contract o = e.ContractDetails.Summary;
                    desc = string.Format("Option for {0}, Id: {1}, Right{2}, Expiry:{3}, Strike:{4}", e.ContractDetails.Summary.Symbol, o.ContractId, o.Right, o.Expiry, o.Strike);
                    break;
                case SecurityType.Stock:
                    Contract eq = e.ContractDetails.Summary;
                    desc = string.Format("Equity {0}, Id:{1}", eq.Symbol, eq.ContractId);
                    break;

            }
                    Console.WriteLine(desc);

        }
