Hi xavier.affringue,
See an example below
namespace cAlgo
{
[Indicator(IsOverlay = true, TimeZone = TimeZones.UTC, AccessRights = AccessRights.FullAccess)]
public class NewIndicator : Indicator
{
[Parameter(DefaultValue = 0.0)]
public double Parameter { get; set; }
[Output("Main")]
public IndicatorDataSeries Result { get; set; }
private Form1 _f1;
private Thread _thread;
protected override void Initialize()
{
_f1 = new Form1();
_thread = new Thread(() => _f1.ShowDialog());
_thread.SetApartmentState(ApartmentState.STA);
_thread.Start();
}
public override void Calculate(int index)
{
// Calculate value at specified index
// Result[index] = ...
}
}
}
Best Regards,

Hi xavier.affringue,
Yuo will need to create a public function in the form, pass the price as a parameter and print the value on a label.

Hi xavier.affringue,
Yes you can add a label in the form designer as well. Exactly as you would in a typical WinForms project.

I have explained this above. You need to create a public function in the form, pass the price as a parameter and print the value on a label.

Hi,
If you mean the chart UI controls, then this is not possible. WinForms have their own controls. You can drag them on the form editor from Visual Studio toolbox.

Hi xavier.affringue,
It seems you just copied and pasted code expecitng it to work. To add a WinForm to your project, it is better to edit the indicator in Visual Studio and add a new form as a new class. Then initialize it and load it from the Indicator. Also, you cannot access the Symbol information from a form since this is not a property of the form but a property of the indicator. You need to pass this information as a parameter.
Best Regards,
Panagiotis
