Draw.Line() Global doesn´t works

[Nutriax]

Hi team,
I am trying to draw a line from my indicator script and I want to this line be global, so I can see the line in the ES chart for candle or ticks, but it doesn{t works.
I use the following code to draw the lines:

Draw.Line(this,lineNameBefore+"2",true, basrAgo,barsAgoY,0,barsAgoY,""); 

the results is in the screenshots.
What I am doing wrong? the global only works with the same type of charts?

Thanks in advance.

Hello Nutriax,

Thanks for your post.

A global draw object will appear on all charts of the same instrument (unless "show global draw objects" is specifically excluded in the Data series settings)

In order to draw a global line you would need to use the Draw.Line() method overload that uses the bool IsGlobal. The one that fits what you have posted would be:

Draw.Line(NinjaScriptBase owner, string tag, bool isAutoScale, int startBarsAgo, double startY, int endBarsAgo, double endY, bool isGlobal, string templateName)

I will move this thread to the NinjaTrader8 indicators forum.

Hello, thank you for your quick response on this.
I already checked and I have enable the "show global draw objects" in the data series of the ticks chart, but it is not displaying the lines.
Also I used the same reference that you sent and the lines are drawed in the original chart (which has the indicator) but not in other ones, as I show you in the previous screenshot.)
What else can I try?

Thank you for your help on this.

Hello Nutriax,

Are you using the Drawing method overload that allows specifying isGlobal like Paul suggests?

When I test the method overload Paul suggests, I see the global drawing object on other charts of the same instrument.

Please see the attached script and screenshot for a working example.

Hello Jim/Paul,
Thank you very much for your support on this, its working now! I had a problem at my side and I was able to figure it out when I review the example code that you posted Jim.

I really appreciate! thanks a lot!

If i want to change the color and the size line, Is it posible using global drawing object ?

Hello faroka,

Thank you for your note.

Although it is expected that a NinjaScript change of a global drawing object would not take effect on all charts, I recommend reviewing the sample provided in the following forum post:

https://ninjatrader.com/support/forum/forum/ninjatrader-8/add-on-development/1178711-drawing-tool-context-menu-handler-with-global-drawing-objects?p=1179659#post1179659

My colleague Jim created that sample that demonstrates how to loop through all windows. It then takes all windows that are charts and loops through the ChartObjects to look for a DrawingTool, then finally it checks if the object is a Global DrawingTool. Then you may update all instances of the global DrawingTool - this approach would allow you to change the color and size of the global drawing objects.

Please let us know if we may be of further assistance.
