Within the Control Center window, select the Tools-->Account Connections... menu. This will launch the Account Connection Set Up window. A connection is where you set up your user name, password  and any relevant information that allows you to establish a connection to your connectivity provider which is your broker and/or data feed service. You can access broker/technology specific connection help information via the NinjaTrader website Support Center.

Within the Account Connection Set Up window you can establish a connection, add a connection, change a connection or remove a connection. The following steps uses eSignal as connectivity provider. This provider is used for demonstration purposes.

1. Press the "Add..." button to launch the connection wizard.

2. After pressing the "Next" button, you will be prompted to supply:

• User defined connection *name
• Select the connectivity provider
• Optional back up data feed connection
• Historical Data Options (visibility of these options are dependent on the provider and your license)

* Only use alphanumeric characters in the connection name

3. After pressing the "Next" button, you will be presented with provider specific parameters that you must enter in order to establish a connection. Each different provider may have different options. For specific information relative to your connectivity provider, select the Connection Help... menu from within the NinjaTrader Control Center window.

4. Once you have entered in all of the required connectivity information and pressed the "Next" button, your set up information will be presented to you at which time you must press the "Finish" button. The newly created connection will be displayed in the Account Connection Set Up window window and from the File-->Connect-->Your Connection menu in the Control Center window.
