Ensign 10 and Ensign Windows can receive the Interactive Broker feed through the IB Gateway or through the IB Trader Workstation. The advantage of the IB Gateway is it does not have the overhead of showing a quote page or trade platform. Also, the IB Gateway is not required to be shut down each day whereas TWS does shut down.
Get the IB Gateway from the IB web site using this link. It installs with the TWS.
Gateway can be found in the Start menu, All Programs | Interactive Brokers folder. Drag the Gateway icon to the desktop so there is a desktop link named IB Gateway.
For Ensign Windows, run Gateway and manually connect. Ensign Windows will find Gateway running and connect to it to receive the feed from Interactive Brokers.
For Ensign 10, check the box Use IB Gateway instead of TWS found on the Setup | Feeds form. Ensign 10 can run IB Gateway and accomplish the login process.
IB Gateway uses the same Username and Password as is used by TWS. Note in the above example that the Reconnect time has been blanked out which is appropriate since Gateway remains running and does not need to be rerun by Ensign each day.
To log in to IB Gateway the 1st time, you need to change the bullet selection to IB API. Then enter your Username and Password.
You must change the port setting that Gateway listens on for Ensign to connect to it. In Gateway, click menu Configure | Settings | API | Settings and change the port to 7496. And create the entry in Trusted IP Addresses for 127.0.0.1 as shown here.
