I want to capture the input parameters for an indicator of a C # form. The call of the OnBarUpdate method should be avoided until the form is closed.

My first idea was:

 

Code

public class ParmsForm : Form public ParmsForm () { this.Text = "C# - einfaches Form"; this.Size = new Size(600, 400); AddContextMenuAndItems(); addControls(); } }

I call the modal form from inside the OnStartup method:

 

Code

protected override void OnStartUp() { ParmsForm parmsForm = new ParmsForm(); parmsForm.ShowDialog(); }

The form is displayed. However, the OnBarUpdate method is called before the form is closed. My parameters are thus in the indicator is still not known.

Then i tried

 

Code

DialogResult dr = parmsForm.ShowDialog(); while(!parmsForm.IsDisposed) Thread.Sleep(10);

Same result as above.

Does anyone provide any solution or idea?

I think you can find some working examples from some old code from @piersh who made a Genetic Optimizer for NT 6.5. It was a strategy class code, but the actual code itself should be the same obviously for an indicator in regards to the form generation and input.

You can download it here and look at the source:

NinjaTrader Genetic Optimizer Latest version (1.12), with NT7 support, is here ( Hi All, I've created a new Genetic Strategy Optimizer based loosely on Peter's GAOptimizer. Installation Instructions: - download the .ZIP file from the download link (above). NOTE: ignore …

Hello Mike, thanks for the link.

I have the following problems:
1. After installation "PH Genetic " in "NT 7.01 Live" I can't select "PH Genetic" because i can not see an appropriate selection dialog.
2. Unfortunately, I do not find the place in the Sourcedcode where for e.g. the Form 'OptionsDialog: is invoked .

Do you have another tip?

Thanks, Eddy

It was for NT 6.5, not 7, if I recall (since 7 has a GO already).

The point was to look at the source. Just look for forms or parameters with x,y coords, you can see it from there. I believe it's standard winform stuff, you could buy a book on it and get the basics.

My problem is not to create a WinForm. The problem is, how can i call a WinForm from inside the NT parameter dialog.

I use the PHGenetic in NT7 ... the native GO is slower in my estimation

Yes, but the native GO is reliable.
@Trader.Jon, didn't you find strange results with the PH Genetic GO ?

sam,

Are you saying MORE reliable? In what way is the native GO better?

I haven't use the PHGenetic gave me false results:
- take the optimal parameters found by the PHGenetic
- launch simple backtest with only these parameters
then compare the results of both.
You will have some surprises...
