Importing A License Key
If you have a License Key that has not been imported to your NinjaTrader Account automatically, you may import it manually from the Settings > Plans page of your NinjaTrader Account Dashboard.
After selecting "Import a license key", copy and paste the full License Key into the text box and click Submit. This will unlock access to the Account Plan and any Account Add-ons associated with the License Key on the NinjaTrader Username used to log into any NinjaTrader platform
Note: The Help > License Key window is no longer present on NinjaTrader Desktop 8.1. You no longer need to input your License Key on the Desktop app after upgrading to NinjaTrader 8.1.
