How to obtain values from another Indicator using ACSIL

How do we go about in obtaining Values from another indicator?

I remember seeing a guide on Sierra but can't seem to find it. I've done the following but my array is empty.

Code

// Get the study data from the specified chart
    sc.GetStudyArraysFromChartUsingID(Input_Subgraph3Reference.GetChartNumber(), Input_Subgraph3Reference.GetStudyID(), StudyData);

    //Check if the study has been found.  If it has, GetArraySize() will return the number of Subgraphs in the study.
    if (StudyData.GetArraySize() > 0)
    {

        // Define a reference to the first subgraph array
        SCFloatArrayRef Array1 = StudyData[0];

        // Check if array is not empty.
        if (Array1.GetArraySize() != 0)
        {
            // Get last value in array
            float LastValue = Array1[Array1.GetArraySize() - 1];
        }

    }

How do we go about in obtaining Values from another indicator?

I remember seeing a guide on Sierra but can't seem to find it. I've done the following but my array is empty.

Code

// Get the study data from the specified chart
    sc.GetStudyArraysFromChartUsingID(Input_Subgraph3Reference.GetChartNumber(), Input_Subgraph3Reference.GetStudyID(), StudyData);

    //Check if the study has been found.  If it has, GetArraySize() will return the number of Subgraphs in the study.
    if (StudyData.GetArraySize() > 0)
    {

        // Define a reference to the first subgraph array
        SCFloatArrayRef Array1 = StudyData[0];

        // Check if array is not empty.
        if (Array1.GetArraySize() != 0)
        {
            // Get last value in array
            float LastValue = Array1[Array1.GetArraySize() - 1];
        }

    }

I *think* you have to do something like this:

Code

SCSFExport scsf_StudyName(SCStudyInterfaceRef sc)
{

     // Define a reference to the first subgraph array
      
    SCGraphData StudyData;
    SCFloatArrayRef Array1 = StudyData[0];



// Get the study data from the specified chart
    sc.GetStudyArraysFromChartUsingID(Input_Subgraph3Reference.GetChartNumber(), Input_Subgraph3Reference.GetStudyID(), StudyData);


    Array1 = StudyData[0];

    //Check if the study has been found.  If it has, GetArraySize() will return the number of Subgraphs in the study.
    if (StudyData.GetArraySize() > 0)
    {
        // Check if array is not empty.
        if (Array1.GetArraySize() != 0)
        {
            // Get last value in array
            float LastValue = Array1[Array1.GetArraySize() - 1];
        }

    }
}

If that doesn't work, maybe one of the ACSIL gurus around here can straighten us out.

Yeah same thing...

Yeah same thing...

Is the indicator you are trying to access located on the same chart or a different chart?

If on a different chart, is that chart in the same chart book and using the same time frame as the primary chart?

And what is the indicator you are trying to access?

It's and indicator that was added on the chart. It is the bollinger squeeze. So this is getting plotted below the main chart...

It's and indicator that was added on the chart. It is the bollinger squeeze. So this is getting plotted below the main chart...

I did a quick setup of the Bollinger Squeeze like this:

Code

SCSFExport scsf_StudyName(SCStudyInterfaceRef sc)
{

    SCGraphData StudyData;

    sc.GetStudyArraysFromChartUsingID(1, 10, StudyData);

    SCFloatArrayRef Array1 = StudyData[0];
    
    float test = Array1[sc.Index];
	
}

And test shows the value for the Bands Ratio (SG1).

Since the subgraph reference is 0-Based...

If I change to this:

SCFloatArrayRef Array1 = StudyData[1];

Then test shows the value for the Squeeze Indicator (SG2)

If you still can't access your indicator values like that, then not sure what's going on.

One thing to check: Click on Analysis -> Studies and make certain all your Study IDs are sequentially numbered. I seem to recall that if there is a missing Study ID number in the middle, studies after that can't be accessed.

So if you had five studies, IDs 1, 2, 3, 4, 5... and you deleted Study 3, and were left with 1, 2, 4, 5... then study 4 and 5 can't be accessed. As I recall, that happened to me in the past and I had to delete 4 and 5 and re-add them as 3 and 4.

But don't quote me on that! lol

Wow! It ended up being that I had 2 charts open. So It was throwing me off....I appreciate your input on this. You really helped me navigate this wonderful world of Sierra ACSIL programming.
