Installing 3rd Party Add-Ons

After you have downloaded 3rd Party Add-On, they can be imported from the NinjaTrader Control Center.

 2. Select the file you want to import

 3. Press the "Import" button

Understanding the impact of installing Add-Ons

NinjaTrader provides a development environment allowing low-level access to 3rd party developers to build integrated indicators, drawing tools, automated strategies and more. An Add-On with software bugs can have adverse effects on the entire NinjaTrader application. These add-ons also natively run on your computer, therefore, its important to only install 3rd Party Add-Ons from sources you trust.

The following symptoms post installation could indicate an Add-On is installed causing negative impact:

•Windows become slow or unresponsive to user interaction

•Market data becomes unusually slow to load or update

•Standard features fail to work as designed

•Other scripts fail to work as designed (custom scripts that work on their own may conflict with each other)

•Lost connections from market data providers

•Error messages are generated at various times

•The entire application shuts down abruptly and without warning

If you run into any of the above symptoms post installation of a 3rd Party Add-Ons please try uninstalling the 3rd Party Add-Ons to see if the problem goes away and contact the 3rd party developer for support.

Updating Add-Ons

Developers can issue updates to fix issues or add functionality. If you have obtained an updated copy of your 3rd Party Add-On, you can import the new version using the same steps you originally used to install by going to Tools > Import > NinjaScript Add-On... and selecting the new file.  During the import process, you will be given an option to replace the current Add-Ons which exists on your PC, which you should accept for each file you wish to update.  

Removing 3rd Party Add-Ons

Should you identify a problem, or suspect a 3rd Party Add-On is causing problems, you may wish to remove these files from your system.  The exact steps to remove will depend on how it was distributed. 3rd Party Add-ons can be installed either as a "Protected Assembly" or "Non-Protected".  Please see the information below on how to proceed.

Removing Protected 3rd Party Add-Ons Assemblies

If you have purchased a 3rd Party Add-On, it is likely distributed as a Protected Assembly.  These protected files can be uninstalled by going to Tools > Remove NinjaScript Assembly.  If you cannot find the 3rd Party Add-On from this dialog, your Add-On is most likely a non-protected assembly.

Removing Non-Protected 3rd Party Add-Ons

Most free 3rd Party Add Ons downloaded from online forums and other communities are distributed as unprotected c# scripts.  These open-source files can be uninstalled using the following steps:

1.From the Control Center window select the menu New > NinjsScript Editor to open the NinjaScript Editor

2.On the right side, under the "NinjaScript Explorer" expand the type of folder of the 3rd Party Add-On you are trying to uninstall

3.Locate the name of the 3rd Party Add-On (Note: 3rd Party Add-Ons can be installed in several sub-folders)

4.Right click on entry > select "Remove"

Temporarily disabling Add-Ons

Should you start to experience an issue with NinjaTrader, the first step to isolate the problem is to determine if you continue to experience issues without Add-Ons enabled referred to as 'Safe Mode'. To enable safe mode, please use the following steps:

1. Exit NinjaTrader

2. Hold the CONTROL key on your keyboard and double-click the NinjaTrader icon.

3. Keep the CONTROL key held down until you see the NinjaTrader Control Center

4.Once you see the Control Center, you can verify you are in safe mode by going to Help > About.

Once in safe mode, you may use NinjaTrader without 3rd party add-ons, allowing you to verify if a problem no longer is present or allowing you to remove a 3rd party add-on.
