Print inside a custom class

[JeffCO7]

I have a custom class in NT8 that I use in multiple indicators.

Console.write compiles but does not write to an accessible screen in NT8

I understand from hints in other threads that I can somehow use Print in my custom class to print to Output 1.

Here is an outline of my code where "TestIndic" is an indicator using my custom class and "TestCommon" is my common custom class.

namespace NinjaTrader.NinjaScript.Indicators.MyCommon
{
   public class TestCommon
   {
      int Param1;
      double Param2;
      double myMagic = 1;
      public TestCommon (int param1, double param2)
      {
         Param1 = param1;
         Param2 = param2;
      }
   }

   public double DoGreatStuff ( ISeries<double> price )
   {
      Print ( String.Format( " The Magic : ",myMagic ) ); // <---- ??? Print is out of scope in TestCommon -- How do I use Print in my custom Class ???
      return price[0] * myMagic;
   }
}


namespace NinjaTrader.NinjaScript.Indicators
{
   public class TestIndic : Indicator
   {
      public int MyParam1 = 1;
      public double myParam2 = 2.0;
      public double myResult;
      public TestCommon myTest;

      protected override void OnStateChange()
      {
         if (State == State.DataLoaded)
         {
            myTest = new TestCommon ( MyParam1, MyParam2 );
         }
      }


      protected override void OnBarUpdate()
      {
         myResult = myTest.DoGreatStuff ( Close );
      }
   }
}

Thank you in advance for your help

Hello JeffCO7,

Thank you for your post.

In most cases Print() can be used but if you're running into issues where you're outside the NinjaScript scope, instead of Print(), use Output.Process() to write a message and instead of ClearOutputWindow(), use Output.Reset() to clear the output window.

// Instead of Print()
NinjaTrader.Code.Output.Process("my message", PrintTo.OutputTab1);

// Instead of ClearOutputWindow()
NinjaTrader.Code.Output.Reset()om/support/helpGuides/nt8/alert_and_debug_concepts.htm

That being said, it looks like you should be in the NinjaScript scope and Print should work for you, but it looks like you don't have String.Format set up correctly:

Print(String.Format( " The Magic: {0} ",myMagic ));

Please let us know if we may be of further assistance to you.

NinjaTrader_Kate,
Thank you. I just hand jammed the sample code here to describe my situation and missed the {0} in the String.Format as I did not compile it.

I tried

    NinjaTrader.Code.Output.Process( "my message", PrintTo.OutputTab1 );

It compiled and it DID WORK. Woohoo!! ( I originally missed the PrintTo.OutputTab1 and it would not compile with one argument - sorry for the false alarm.)


Question: When I try to use Print, it has a NinjaScript compile error of "The name 'Print' does not exist in the current context"

Any thoughts since you think it should be in context? Am I missing a using statement?

Hello JeffCO7,

Thank you for your reply.

I got some clarification on that, and Print() is available to indicators and strategies. NinjaTrader.Code.Output.Process() would have to be used in a custom class that doesn't inherit from indicator or strategy, but if you supplied the indicator to the custom class, the print could be used through the indicator

myIndy.Print("some text");

Please let us know if we may be of further assistance to you.

@Ninjatrader_Kate,

Thank you. I think the NinjaTrader.Code.Output.Process is the solution for my current context. I have been struggling with workarounds for some time.

This was a great solution.
