VendorLicense

[mktforecast]

I'm having some difficulties to understand the VendorLicense code that I should write in my indicator. Do I have to write it in my indicator code or elsewhere ? How do I call the function VendorLicense.

The code below has been taken here -->> https://ninjatrader.com/Downloads/Ve...LicenseDemo.cs

In the code below, let's say I wanna code the indicator named MovingAverage

Firstly, do I write this code directly in the code of the indicatory that I developed ? Next see the questions in red below.

//This namespace holds Indicators in this folder and is required. Do not change it.
namespace NinjaTrader.NinjaScript.Indicators
{
public class LicensedIndicatorDemo : Indicator --->> IS IT MY INDICATOR MOVING AVERAGE CLASS OR IS IT FOR THE VENDORLICENSE FUNCTION ??
{
// Place your vendor licensing in the default constructor. This guarantees, that your licensing
// could not be overwritten later by fraudulent hackers who e.g. would derive from your class.
// Note, that your code only ever should call 'VendorLicense' once.
public LicensedIndicatorDemo() -->>> IS IT MY INDICATOR MOVING AVERAGE OR A FUNCTION 100% RESERVED TO CALL VendorLicense
{
//When no custom configuration is needed, the arguments below will suffice:
VendorLicense("NT", "Module", "www.your-url.com", "[email protected]",null);

/*VendorLicense("YourVendorName", "YourProductName", "www.your-url.com", "[email protected]",
// This optional callback is triggered right before the actual license verification and allows
// you to delay the configuration.
// It's defaulted to NULL if not provided. License verification then is triggered as configured above
() =>
{
// The following demonstrates how to set up additional custom configuration for license verification.
// For example, if you planned to offer the indicator for free for use with indexes only, you could skip
// the verification process like below:
if (Instrument.MasterInstrument.InstrumentType == InstrumentType.Index)
return false;

// For all other instruments the already configured license verification is triggered.
return true;
});*/
}

Hello mktforecast,

Your indicator class name will be the class name of your indicator and not 'LicensedIndicatorDemo' which is the name of the demo indicator you were provided.

The class name will reflect the name of the indicator. The example indicator you were provided is named 'LicensedIndicatorDemo'.

The VendorLicense() method call will be in the Constructor of the class.

namespace NinjaTrader.NinjaScript.Indicators        <-- this is the namespace path the MyClassName class is within the scope of.
{
public class MyClassName : Indicator                <-- this is the declaration of the class of the indicator, it inherits from Indicator.​
{
public MyClassName()                                <-- this is the constructor for the class
{
// code run when class is constructed here          <-- this is where the VendorLicense() call goes, in the class constructor
}
}
}

Below is a link to a 3rd party educational site on how C# works and demonstrates a class constructor.

https://www.w3schools.com/cs/cs_constructors.php

As well as a link to the Microsoft documentation on the class constructor.

Thank you Chelsea I now understand where the VendorLicense call goes.

However, I'm wondering if my indicator code goes in the public MyClassName or below.

namespace NinjaTrader.NinjaScript.Indicators <-- this is the namespace path the MyClassName class is within the scope of.
{
public class MyClassName : Indicator <-- this is the declaration of the class of the indicator, it inherits from Indicator.
{

public MyClassName() <-- this is the constructor for the class
{
// code run when class is constructed here <-- this is where the VendorLicense() call goes, in the class constructor
}

Then I put my code here outside of the MyClassName() ????


}
}

Hello mktforecast,

Yes, other methods should not be in the constructor.

OnStateChange() should be within the scope of the class.

OnBarUpdate() should be within the scope of the class.

Have a look at the ADL (or any indicator) included with NinjaTrader to see where methods are placed in the class.
