Licensing User Authentication
Licensing/User Authentication
NinjaTrader provides a free vendor license management service for user authentication to qualified 3rd party developers.
The service includes the following features:
- One method call within your NinjaScript indicator or strategy’s constructor will enable the authentication process
- A NinjaScript AddOn dedicated to license management (Manage license, provide free trials)
- Licenses are exclusively tied to a combination of user-defined prefix + PC machine ID value, ensuring that licenses cannot be shared
- Manage all of your individual products, or group products together for licensing
- Licenses expire based on time/date
- Create free trial periods
For more information please contact [email protected] or your NinjaTrader Business Development representative. Once approved, you will receive a unique Vendor ID used to manage your user licenses, a Vendor Licensing Help Guide containing information, samples, and resources to guide you through the process of managing licensing.
