Create a Window Similar to NinjaTrader's ???

[ninZa]

Hi,

I want to make a custom alert window for my indicators.
I find NinjaTrader's windows very elegant and professional with a nice red-box title at the left top.

Can we create a NinjaTrader-style window, then add our custom contents?
Does NinjaTrader support us to do this?

Thank you very much.

Yes, you can and this is supported through the new AddOn framework.

You can use the NTWindow class which will allow you to style your windows like NinjaTrader 8's.

You can also use various controls like the instrument and interval selector.

Please see the attached AddOn which will demonstrate how this can be done.

There is also some limited documentation available which is currently a work in progress while we're in beta.

It's great that NT supports this. I will check and learn from the documentation to build a custom NT-style alert window.

Basically, I will have to create an addon file, and in my indicator I call the addon, right? Can you let me know if NT automatically includes the addon file in the indicator export, and then users can import it normally using the indicator import feature of NT?

Thanks.

Yes, I would expect it to but found a bug while I was confirming that and have reported using ID # 9091

Thanks Matthew.

Is it a correct approach if I don't write an addon. Instead I write the class directly in my indicator source code:

internal class AlertWindow : NTWindow {

public AlertWindow() {

Caption = "Alert window";
Width = 300;
Height = 300;

}

}

Then create an AlertWindow object and Show() it when needed in the indicator?

Just a quick idea coming to my mind.

Thanks.

Hello ninZa,

You could go that route. I have seen this used with NT 8 indicators in the manner you detailed.

Wonderful. Where do you see that, Patrick? Is it possible to post the indicator's code here as a reference/guide?

Thank you very much.

Hello ninZa,

Thank you for your patience.

Attached is an example of adding a button to the chart that can open a new window from the indicator. If you have any questions please let me know.

Thank you Patrick.

Because I could not manage to build the custom window based on NTWindow, I've build it from Window class. But thanks to your code I will definitely resume investigating the possibility with NTWindow. No special codes different from mine, but my version didn't work while yours work. Maybe it's Globals.RandomDispatcher that makes the difference?

I will study this and let you know.

Thank you.

Update: I've successfully built a custom NTWindow, no matter I use Globals.RandomDispatcher, this.Dispatcher, or ChartControl.Dispatcher to BeginInvoke (or Invoke) the action.

My original codes (that didn't work) are not different from yours. What was wrong with it ! Perhaps I made a stupid mistake somewhere.

Thanks Patrick.

I know the reason

• I put the NTWindow-based class inside the indicator class
• You put the NTWindow-based class OUTSIDE the indicator class

So we have to put it at the same level as our indicator classes, inside the namespace NinjaTrader.NinjaScript.Indicators.

Using a naming convention (e.g. with a prefix) can prevent the error "The namespace already contains a definition for...", but this is not something really cool.

I am glad you found the resolution here.
