Default Constructor

[mlarocco]

I am trying to add Vendor Licensing to my strategy but I am not familiar with using a default constructor. The strategy will compile, export and import ok, but when I go to add the strategy to a chart, I get an error.... Any guidance you can provide would be appreciated. Here is part of the code...

#region Using declarations

}

private bool isAtmStrategyCreated = false;

Hello mlarocco,

Do you get this error when you add the vendor licensing line of code specifically or with the constructor by its self? I would suggest to remove the vendor licensing part and make sure that it can export/import and apply correctly when using a compiled/protected assembly. If that works you would need to try the constructor by its self without the vendor license code and repeat that test again.

The strategy imported and would apply to the chart without error before the VendorLicense lines were added, it also worked correctly. I get the error when I open the strategy window (video below). Sorry, I don't know exactly what a constructor is or what the code looks like for it, this is the first time I've tried adding vendor licensing to any indicators/strategies.

I think I found the problem, it seems it didn't like the underscore in the product name. I removed it and the error is gone

Hello mlarocco,

Thanks for the update. That would make sense, the platform prevents you from using underscores when you generate new files using either the strategy builder or the editor. In the future I would suggest to create the script using those tools just to make sure the name you used is completely valid.

You can still use an underscore in the Name= "" string if you wanted it in the UI, alternatively you can use a Space in the actual Name property.
