NinjaScriptProperty

[esignal]

hi,
i need to call myClass by Different ways

Example:

P1Class(int i);

P1Class(int i, string s, double d);

how can i create class in this way? i can setting attribute [NinjaScriptProperty]
but only 1 time

thanks

Hello esignal,

This would be general C# and would not be specific to NinjaScript.

For multiple overloads, you need to declare the method multiple times with different overloads.

public void MyMethod()
{

}

public void MyMethod(int intVariable)
{

}

Below is a public available link to an educational site that discusses overloads.

i don't want to call method...but class indicator :
Examples :

P1Class(i).Pippo(3);
or
P1Class(i,"tttt",9.2).Pippo(3);

is not method but class costructors i think..and when i create indicator i don't use constructors..i use attribute [NinjaScriptProperty] in the property


Look @swing :
...
...

#region NinjaScript generated code. Neither change nor remove.

namespace NinjaTrader.NinjaScript.Indicators
{
	public partial class Indicator : NinjaTrader.Gui.NinjaScript.IndicatorRenderBase
	{
		private Swing[] cacheSwing;
		public Swing Swing(int strength)
		{
			return Swing(Input, strength);
		}

		public Swing Swing(ISeries<double> input, int strength)
		{
			if (cacheSwing != null)
				for (int idx = 0; idx < cacheSwing.Length; idx++)
					if (cacheSwing[idx] != null && cacheSwing[idx].Strength == strength && cacheSwing[idx].EqualsInput(input))
						return cacheSwing[idx];
			return CacheIndicator<Swing>(new Swing(){ Strength = strength }, input, ref cacheSwing);
		}
	}
}

in this code there is Overload..but it is built in ninjatrader when i compile it..

Hello esignal,

Any code you change in the NinjaScript generated code will be undone when the script is compiled.

The code you add will need to be outside of this region.

You can add a partial Indicator class that extends the indicator base and create an additional method with different overload parameters similar to the dotnetperls guide I have linked in my previous post.
(This is basically the same as the NinjaTrader generated code but with your own custom methods and outside of that region)

However, keep in mind, this is outside of what is supported by NinjaScript support.

ok..i do it...

But when i compile , it give me error
It create in automatic this code :

Hello esignal,

Is the entire script?

This will not compile. The entire indicator class is missing.

Hello esignal,

what i missing?...you say "You can add a partial Indicator ,,"

i add it :

 
namespace NinjaTrader.NinjaScript.Indicators
{
    public partial class Indicator : NinjaTrader.Gui.NinjaScript.IndicatorRenderBase
    {
 
        public MainTrendAnalisys MainTrendAnalisys1(int contaBarre)s
        {
 
            return MainTrendAnalisys(Input, contaBarre);
        }
 
    }
}

MaintrendAnalisys is an indicator present in folder bind/custom/indicator

Hello esignal,

When I mentioned you can add a partial class, I was not suggesting you should erase the indicator class.

The errors are likely occurring because the NinjaTrader generated code is referencing the Indicator class that was deleted.
