NT8 script password protected

[sunlounger]

Hello, I want to program my main strategies, and of course it is going to cost me a decent amount of money, a few thousands probably. So I have the idea to sell my scripts to other traders in order to cover my expenses and maybe even scratch some profits.

The problem is that after I send it to someone, anyone can copy and give it for free to the others, so my question is how can I protect my script with a password, so it ca be used by only one user and not be able to be copied? Or maybe it should be some sort fo subsribtion, I have no idea, this is why I am asking.

Thank You

Password? No idea.
Passwords are not normally done.

You may be thinking of licensing.

NT has a free licensing facility available to vendors. If
you don't want to become a vendor, you can buy a 3rd
party licensing service for .NET assemblies, or you can
build your own.

[If you plan to commercialize and sell to others, then ask
NT support about becoming a vendor. But if you just plan
to provide for family and friends, and perhaps sell a few in
the process, you can always start by using a home grown
solution using a builtin table of customer MachineIds. That
is, your indy/strat checks the current MachineId and if that
MachineId is not in your internal list, you popup an error
message and call SetState(State.Terminated) which will
prevent your indy/strat from running on unauthorized
machines. I've done this, works great.]

The second thing you want to do is protect the compiled
code, so that the DLL you distribute is obfuscated/encrypted
and cannot be disassembled.

You'll want the Agile.Net addon for this. It costs $100/year.
See here.

Commercial distribution is a rather hefty sub-topic.

Start by looking here.

Good luck!

Hello sunlounger,

Thank you for your inquiry!

The power to manage who has access to the code via machine ID, and then further obfuscate your code, is part of our vendor licensing tool. The vendor licensing service you're interested in is only available to our vendors and is part of the free NinjaTrader Vendor Program.
Our Business Development team would be happy to walk you through the steps. Please reach out to them at info[AT]ninjatraderecosystem[DOT]com

Thank you for using NinjaTrader.
