access to variables from indicator in strategy

[sidlercom80]

Hello , I only get a zero value from the variable, why? As an example I use the SampleBoolSeries.cs and MyCustomIndicator.cs

SampleBoolSeries

public class SampleBoolSeries : Indicator
{
   private double exposedVariable;

   protected override void OnBarUpdate()
   {
     exposedVariable = Close[0]; Print(ExposedVariable);
   }

   public double ExposedVariable
   {
     get { Update(); return exposedVariable; }
   }

MyCustomIndicator

public class MyCustomIndicator : Indicator
{
   SampleBoolSeries boolSeries = new SampleBoolSeries();

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

the goal is to make calculations in a file (indicator.cs) and then use them in a separate file (strategy.cs)
I don't understand why a 0 appears, the access to the variable should be set right. can someone please give me a tip, that would be great

Hello sidlercom80,

One problem here is that you never actually call the indicator to have it process, you only try and access the property. The property is only going to be set if OnBarUpdate processes.

Generally you will need to either access a Plot or Series like shown in the sample in addition to the public property. You can also try using Update from the strategy like the following:

protected override void OnBarUpdate()
{
boolSeries.Uppdate();
Print(boolSeries.ExposedVariable);
}

If the indicator will have any plots you should avoid calling update and just call one of the plots:

double dummyValue = boolSeries.MyPlot[0];

If you are not able to see the script working, could you attach the strategy and indicator test so I can run what you have?

I look forward to being of further assistance.
