Need Help with Exposing Indicator Values

[Rainmakersg]

Hi, I have a simple sender indicator that exposes its values and a receiver indicator that reads the value:

Sender indicator:

public class mySender : Indicator
    {
        private Series<double> MySeries;
        private double         exposedVariable;

        protected override void OnStateChange()
        {
            if (State == State.SetDefaults)
            {
               .
               .
               .
                
                AddPlot(new Stroke(Brushes.Cyan, 3), PlotStyle.Line, "MyLine");
                MySeries             = new Series<double>(this);
                //MyBool            = false;

        protected override void OnBarUpdate()
        {
            if (CurrentBar < 2)
            {
                return;
            }

            MySeries[0]     = (Open[0] + Close[0])/2;
            MyLine[0]       = SMA(MySeries,10)[0];
            
            exposedVariable = MyLine[0];
            
        }

        public double ExposedVariable
        {
            get { Update(); return exposedVariable; }
        }
        
        #region Properties
        [Browsable(false)]
        [XmlIgnore]
        public Series<double> MyLine
        {
            get { return Values[0]; }
        }

        /*
        [NinjaScriptProperty]
        [Display(Name = "My Bool", Order = 1, GroupName = "Settings")]
        [XmlIgnore]
        public bool MyBool
        { get; set; }
        */
&#8203;
        #endregion​ 

Receiver Indicator:

protected override void OnBarUpdate()
{
       Print(mySender().ExposedVariable);
}​ 

Both indicators are working fine. However, when I removed the comments to add MyBool into the code, I get the error from the receiver indicator:
No overload for method 'mySender' takes 0 arguments

I would appreciate assistance to explain what went wrong and what I can do to make it run correctly.

Hi Rainmakersg,

After you add the MyBool property to the mySender indicator, you can pass a true/false value to the mySender() function when calling it.

Please refer to the code below:

protected override void OnBarUpdate() {
    Print(mySender(true).ExposedVariable);
}

William

Hi Williams,

Thanks for the reply. The problem is I cannot even add the MyBool property as the error will show up. MyBool is for other purposes and not related to sender sending out the exposed value.

Hello Rainmakersg,

Below is a link to the reference sample on exposing properties that are not series.

https://ninjatrader.com/support/helpGuides/nt8/exposing_indicator_values_that.htm

From the example:

private double exposedVariable;

public double ExposedVariable
{
// We need to call the Update() method to ensure our exposed variable is in up-to-date.
get { Update(); return exposedVariable; }
}

Hi William, I finally understood what you typed. Thanks so much for your assistance.
