'Draw' does not contain a definition for 'Line'

[AiTrading]

I have a .NET Framework 4.8 DLL project that references:

NinjaTrader.Core.dll
NinjaTrader.Gui.dll
NinjaTrader.Vendor.dll
PresentationCore.dll

I am calling:

NinjaTrader.NinjaScript.DrawingTools.Draw.Line(... )

VS is reporting error:

'Draw' does not contain a definition for 'Line'.

Draw.Text() is there but many other functions are not. I tried to reference NinjaTrader.Vendor.dll from several locations within NT but none have a Draw.Line().

Where can I find the right Draw class?

Thank you

Hello AiTrading,

NinjaTrader.NinjaScript.DrawingTools.Draw.Line is the correct namespace path.

Note, drawing tools can only be called from an indicator or strategy (and no other script types) that is directly inheriting from the indicator or strategy class.

This does not work in a DLL:

namespace NinjaTrader.NinjaScript.Indicators
{
    public class xyz : Indicator
    {
        private Indicator IBase;

        public xyz(IndicatorRenderBase indicator)
        {
            IBase = (Indicator)indicator;
        }

        public void Update()
        {
            if (IBase.CurrentBar > 0)
            {
                Draw.Text(IBase, ...) // OK
                Draw.Line(IBase, ...) // error
            }
        }
    }
}

It appears that Draw.Line is in NinjaTrader.Custom.dll which I cannot reference from my DLL because it creates a reference loop. This is very unfortunate...

Hello AiTrading,

Attached is an indicator that calls Draw.Line() exported as an assembly dll.

Are you seeing the line appear on the chart?

I'm also including the open source version so you can see the code.


The code you have suggested in post #3, is not a valid indicator as it does not implement OnStateChange, or OnBarUpdate().
