Indicator in Strategy

[hectorzx]

Hello.

I have a indicator with 3 plots.

How can i get the plots values of the indicator inside a strategy?

I save in my indicator the last 10 ticks and if I use "MyIndicador(150)[0]", it loose the ticks saved. I have tried to initialize the indicator in the strategy "OnStateChange" but it do not work.

PD: Sry for my english.

Thank.

Hello hectorzx,

Thank you for writing in.

As you have mentioned OnStateChange(), are you referring to NinjaTrader 8?

To call different plots of an indicator, you'll want to access the Values collection.

With three plots on your indicator, Values[0] would denote the first plot, Values[1] the second, and Values[2] the third. The order of these plots is determined by the order of the AddPlot() methods in your indicator's script.

Example:

// this will print the current value of the indicator's first plot
Print(MyIndicator(150).Values[0][0]);

// this will print the current value of the indicator's second plot
Print(MyIndicator(150).Values[1][0]);

// this will print the current value of the indicator's third plot
Print(MyIndicator(150).Values[2][0]);

Alternatively, if you have created your indicator plots through the indicator wizard (and did not manually generate them), the indicator will have public properties that your strategy can access instead.

Here is an example indicator below:

public class MyIndicator : Indicator
{
     protected override void OnStateChange()
     {
          if (State == State.SetDefaults)
               AddPlot(Brushes.Orange, "A");
     }

     [Browsable(false)]
     [XmlIgnore]
     public Series<double> A
     {
          get { return Values[0]; }
     }
}

You can just access the current value of your A plot from your strategy by:

Print(MyIndicator(150).A[0]);
