Multi series indicator

[investor]

Hi,

How should I add an existing indicator within a new one using NT7 ?

I obtained an indicator from a vendor and I would like to access it from within a newly created indicator (or if not possible from a strategy). For instance to determine the Low in a certain period., etc

In NT8 I would use OnStateChange and test if State equals State.DataLoaded to assign the indicator.

NT8:

public class ClassNameIndicator : Indicator
    {

        private NinjaTrader.NinjaScript.Indicators.SomeIndicator SI1;

....

        protected override void OnStateChange()
        {
            if (State == State.SetDefaults)
            {....}
            else if (State == State.Configure)
            {
             AddPlot(new Stroke(Brushes.Yellow), PlotStyle.Dot , "Dots");
...
           }

else if (State == State.DataLoaded)

            {

              // Instantiate the indicator


            SI1  =    SomeIndicator(Close, true, ..);

How would I do this in NT7 ?

Hello investor, thanks for your post.

The OnStartUp() method can be thought of as the data loaded state in NT7. Declare SI1 at the class level the same way as in your code snipped, but call the constructor within OnStartUp.

Kind regards.
