Recommended method to restrict a custom study to a user

Postby sean.dbtrader » 15 Feb 2015

I would like to restrict a custom indicator I've developed to one user. For example I would ask that the user provide me with their User ID and then require that ID in the indicator. However I understand that the User ID will change if a user installs MultiCharts on another computer.

What is the recommended method of restricting an indicator to one or more users?

Yes, but the GetUserName will remain the same for that specific user and his license.

Thanks for your response. Is user name unique for all MultiCharts licenses or can multiple users have the same user name?

Username is unique to the customer.

If the customer has more than one licenses under the same name,
all the MC installations will return the same Username.

My username is unique to my license. In that sense it works like the User ID, but with the difference that the username remains the same should I install MultiCharts on another pc.

But not all my MC installations return the same username. For both MultiCharts and MultiCharts .NET, the first license was name 'full name', but additional licenses were numbered ('full name 2', 'full name 3').

When I share my script with a prop firm, I do a number of things

1 - Put an expiration date inside (run time error)
2 - Check for license info (run time error)
3 - Add a password to access the script
4 - Export as read only


Return to “MultiCharts”
