Global Drawing with Labels

[carlosgutierrez]

Hi,
I am developing an indicator that plots some levels with a level description on the right side margin.
First image is the source chart levels (magenta and green price levels) and the label.
The red rectangles seen are breached levels.
The Second image is the same source chart with the Global turned to True. the levels change to a generic blue rectangle. I need these to stay consistent as the original (magenta and green)
On the thirdi mage is another chart (same instument "MNQ") with a clean (no indicator) setup, just the Global drawing showing up. This is where I need to see the same structure as the source chart, magenta & green levels and the lables.

I have not been able to translate the drawing correctly.

Any suggestion to making it happen?

Hello carlosgutierrez,

It is not clear from only the images what the problem is, what specifically are you seeing happen differently between the charts?

[carlosgutierrez]

hey Jesse, I'd like to bee the same style and lables accross charts. Like when you manually select to share the drawing "All Charts" in the object property.

the indicator draws some price levels on the base/source chart, then a boolean in the chart trader enables/disables the "global drawings". Currently, when bool = true = is global true, the current obejcts (draw.ray and labels) are sent to other charts as different object.

how can I get the same drawing all accross?

Hello carlosgutierrez,

To draw a global object from code you would have to use the overload for the tool that has isGlobal. For example a dot:

Draw.Dot(NinjaScriptBase owner, string tag, bool isAutoScale, DateTime time, double y, bool isGlobal, string templateName)
