Using internal indicators within a custom indicator

August 13th, 2020, 01:31 AM

I am having an issue creating a new custom indicator based upon the Wiseman stock indicators from NinjaTrader 8.

I can create a strategy using the Wiseman Alligator and unlock the code and compile with it working.

If I transfer this code over to a new custom indicator and add this line which works fine in the Strategy version, it errors with: 'WisemanAlligator' cannot be used like a method.

The line that works with the strategy but not in the indicator:
WisemanAlligator1 = WisemanAlligator(Close, 13, 8, 5, 8, 5, 3);

NinjaTrader's Help Page... (doesn't work for me):
https://ninjatrader.com/support/helpGuides/nt8/?indicators.htm (Goto Wiseman Alligator)

The example: (doesn't work for me):
// Prints the current value of the teeth for the Wiseman Alligator
double value = WisemanAlligator(13, 8, 5, 8, 5, 3).Teeth[0];
Print("The current Wiseman Alligator teeth value is " + value.ToString());

Any Ideas?

Mmmm. Just a very quick thought (and I have not looked into this at all) - but NinjaTrader have obfuscated the Wiseman suite of indicators. This could be the problem, but as I said this is just a quick guess.

Obfuscation is not related: it's not because an indicator file is obfuscated that it can't export its dataseries value.

@jalley: I did a quick test and I don't see any problem using this code:

Code

                            
public class FooBar : Indicator {

        WisemanAlligator myIndy;        

        protected override void OnStateChange() {

            if (State == State.SetDefaults) {

                Description                                    = @"";

                Name                                        = "FooBar";

                Calculate                                    = Calculate.OnBarClose;

                IsOverlay                                    = false;

                DisplayInDataBox                            = true;

                DrawOnPricePanel                            = true;

                DrawHorizontalGridLines                        = true;

                DrawVerticalGridLines                        = true;

                PaintPriceMarkers                            = true;

                ScaleJustification                            = NinjaTrader.Gui.Chart.ScaleJustification.Right;            

                IsSuspendedWhileInactive                    = true;

            }

            else if (State == State.Configure) {

                myIndy = WisemanAlligator(13, 8, 5, 8, 5, 3);

            }

        }



        protected override void OnBarUpdate() {

            Print(myIndy.Teeth[0]);

        }

    }

I found that the issue is that it will compile fine in NinjaEditor but not in Visual Studio after playing more with it. Wonder what's missing in Visual Studio to cause this.

You can debug NinjaScript with Visual Studio but you can't compile with it.
