If you have a paid subscription with a option price data provider or your broker provides that data to you via a paid account, you can change the default settings in Roo-Trader. To point to the new location for pulling pricing data do the following:
DDE PRICE UPDATES
To update prices via your Broker/DDE, go to: Menu -> Edit -> Preferences & Setup -> DDE (Price Updates). Select the DDE program you have access to (Auto DDE Program Setup) and set the necessary parameters as provided by your DDE account. Your DDE provider should have a web page showing their parameters. Use these to input your data. If your provider is not in the list, we are sorry but it is not currently supported.
