Indicator can't call a compiled protected indicator

[cunparis]

I am trying to use another indicator in my indicator. The other indicator is a compiled & protected indicator. I do something like this:

ProtectedIndicator pi = ProtectedIndicator();

This works when i use the source code of the protected indicator, so the syntax is valid. However when I try it on another PC with the protected compiled indicator, I get an error:

Ninjatrader.Indicator.ProtectedIndicator is a type but is used like a variable.

From what I understand, when we create an indicator Ninjatrader will create helper methods to allow one to just do EMA(20) for example. But if the indicator is protected, it seems these methods are not available.

Am I doing something wrong? Is it possible for an indicator to use another protected indicator?

Hi cunparis,

Try calling the protected indicator creating a strategy in strategy analyzer. Then look at the code to see how the indicator is being called.

If you want to call it without parameters, you will need to use the new keyword.

Thanks for your reply.

I can call it with parameters but the indicator doesn't have any parameters.

If I use the new keyword, the licensing code does not get called and it doesn't work.

How did you get the indicator onto the other PC? Manually by copying the dll or by using the standard zip export/import? In other words, do you have both a dll and a cs file for the indicator in the NT file tree?

I exported the protected into as a zip and imported it. The indicator that will use this one I copied the .cs file. it uses other frameworks so I can't export it as a zip without exporting the other frameworks which I don't want to do.
