InsertComplete

[-=Edge=-]

How would I convert this to NT8? I'm just not seeing it..

ChartControl.ChartObjects.InsertComplete

[NinjaTrader_PatrickH]

Hello Edge,

Thank you for your post.

There would not be an equivelent to ChartControl.ChartObjects.InsertComplete. What are you trying to accomplish? Why were you using InsertComplete in NinjaTrader 7?

I look forward to your response.

Hello Edge,

I look forward to your response.

I am using it in conjunction with a button click to create this event

[COLOR=#006400]private void myMethod(object sender, CollectionEventArgs e) { }[/COLOR]

But the CollectionEventArgs no longer exits either.. and am thinking that maybe I could use this instead..

[COLOR=#006400]private void myMethod(object sender, O[COLOR=#080808]bservableCollectionEventArgs[/COLOR][COLOR=#000000]<T[/COLOR][COLOR=#000000]>[/COLOR]  e) { }[/COLOR]

I believe I have the method working fine, but am struggling with how to create the new event.. Can you point me in the right direction please?




Edit - Modified to button click event...

There are no public events that would match here, we'd like to know how you're using that in NT7 (what exactly are you trying to hook on to? Notify when an instrument changes? An indicator has been added? Drawing tool changed?) so we can provide an existing equivalent in NT8 which would accomplish your goal, or check back with development if there should be something internal that needed to be exposed for your task.

It would probably be easier and much quicker to show you than try to explain in words.. Would this be possible? Skype - edge358 just in case..

This is totally unrelated to what I'm trying to do above, but since you brought it up.. Is there any way of hooking to an event when an indicator has been manually deleted from the chart..

Not so much when it's done thru the indicator property menu, but when you click on the indicator to select it and either use the context menu to remove and/or hit the delete key to delete it from the chart?

I should think that the Garbage Collector would handle that, as there would no longer be a reference to the subscribed instance of the eventHandler in any running code.

Otherwise, I think that OnTermination() would be run before the indicator is removed, so one can unsubscribe there explicitly (which you would have already coded anyway ).

It was actually just a thought around how I might code around an existing issue, but that alone wouldn't completely solve my problem anyway.. So please don't worry about answering..

Currently if you add any type of new button, panel, toolbar, grid, etc to the chart itself (as a child of the ChartControl) thru an indicator, whenever the main grid is updated (for instance after a manual indicator deletion, a change in dataseries property, and possibly even other things that I've yet to run across) it looses track of those objects that were added, and currently the indicator needs to be reloaded to get them back..

I guess what might work is a way of hooking into the grid update event handler, and then forcing the indicator to reload automatically.. But this is already a known issue, and I'm sure they'll come up with something for us..

The ChartScales has as ChartObjects object which is an observable collection and therefore has a CollectionChanged NotifyCollectionChangedEvent. The attached should demonstrate how to use this undocumented feature.

Works perfectly! Thanks!!

Hi...
Once we have the object changed...

Print(e.NewItems[0].ToString() + " was added");

How can we get its details ?

I got this ;
IDrawingTool x = (IDrawingTool) e.NewItems[0];
Print("Name = " + x.Name ) ;
Print("Tag = " + x.Tag ) ;
Print("Panel = " + x.PanelIndex ) ;

but would need to get the Color and the Bars Ago

[NinjaTrader_JessicaP]

Hello pmaglio, and thank you for your question.

You may use the nested ChartAnchors to retrieve BarsAgo information. These are documented here, I recommend using the 0th member.

http://ninjatrader.com/support/helpGuides/nt8/en-us/?idrawingtool.htm

For brushes, I would like to recommend using a C# dictionary to map the IDrawingObject's Tag member, which uniquely identifies the drawing object, to the Brush you used to draw it, at the time you create the object. For example,

[FONT=Courier New] private system.collections.generic.Dictionary<string, Brush> myMap;[/FONT]

[FONT=Courier New]else if (State == State.Configure)
{
    myMap = new system.collections.generic.Dictionary<string, Brush>();
}[/FONT]

[FONT=Courier New]
Diamond myDiamond = Draw.Diamond(this, "tag1", true, 0, Low[0] - TickSize, Brushes.Red);
myMap[myDiamond.Tag] = Brushes.Red;[/FONT]

[pmaglio]

Just one more question....
If my code is not the one painting the object,
so Im just detecting them as it used to be on Ninja 7 with ChartControl.ChartObjects.InsertComplete or now on Ninja 8 with private void myCollectionChanged() as explained by Matthew

Now I have the new detected object on x;
IDrawingTool x = e.NewItems[0] as IDrawingTool;

Is it correct to do this ?
foreach (ChartAnchor anchor in x.Anchors)
{
Print("Bars Ago = "+ anchor.BarsAgo);
}

... because I am not getting a valid result
( I was expecting to get 0 for objects painted on current bar ... 1 for previous bars and so on... but I only get a big fixed integer number )

[NinjaTrader_JessicaP]

Thanks once again for your question, and for using NinjaTrader 8

I am investigating this on our end and reviewing the expected operation of NinjaTrader. I appreciate your patience with this process. Should this not be the expected operation of Ninja I will return with a bug tracking number.

Should this be a NinjaTrader bug, a stripped down code sample from you highlighting what is occurring would be greatly appreciated.

[NinjaTrader_JessicaP]

Hello pmaglio,

I do not believe we will be able to use either the NewItems or the OldItems List. When I use the attached code, both NewItems and OldItems are always null. I believe on your system you may be retrieving uninitialized objects.

In case I may have misunderstood or coded something improperly, would it be possible for you to modify the sample I have attached so that it reproduces the conditions you are observing?
