How to make Draw.Ray visible on all timeframes programmatically?

[handlar]

Hi,
If I want to add, for example, resistance or support level on M15 timeframe and see it on M1 timeframe, manually I do next:
1. Add a new drawing object on M15
2. Change the option "Properties > General > Attach to" from "CL 03-22 15 Minute" to "CL 03-22 (All charts)"
3. Now I can see this added object on any timeframe for CL 03-22, for example
But, if I add a new Draw.Ray() programmatically on M15 timeframe, how can I change "Attach to" property to see I programmatically added Draw.Ray() on all timeframes?
I add a new ray like this:

NinjaTrader.NinjaScript.DrawingTools.Ray ray;
ray = Draw.Ray(this,"level_ray_"+ Time[0], false, 1, levelPrice, 0, levelPrice, Brushes.Green, DashStyleHelper.Solid, 4);

And what next?

ray.AttachedTo.AttachedToType = AttachedToType.GlobalInstrument

- doesn't work, because "Property or indexer 'NinjaTrader.NinjaScript.DrawingTools.DrawingToolA ttachedTo.AttachedToType' cannot be assigned to -- it is read only"

Hello Handlar,

Thank you for your post.

You can use one of these two overloads that takes an "isGlobal" boolean and a templateName. Using this will cause the ray to be drawn on all charts of the same instrument. Note that you must first draw a ray manually, then enter its properties and save it as a template. You will supply that template name to the templateName string.

Draw.Ray(NinjaScriptBase owner, string tag, int st artBarsAgo, double startY, int endBarsAgo, double endY, bool isGlobal, string templateName)
Draw.Ray(NinjaScriptBase owner, string tag, DateTime startTime, double startY, DateTime endTime, double endY, bool isGlobal, string templateName)

Please let me know if I can assist further.

Kate, thank you so much! It was so easy?
One more question: I correctly understood that "templateName" means my own templates I created before?

Hello Handlar,

A simple example:

string mytag = "myRay";
DateTime myDT2 = DateTime.Now;
DateTime myDT1 = myDT2.AddHours(-10);
double myPrice1 = GetCurrentAsk();
double myPrice2 = myPrice1 +10;
string template = ""; //"" for default

var myRay = Draw.Ray(this, mytag, myDT1, myPrice1, myDT2, myPrice2, true, "");
myRay.DrawnBy=null; //== user drwan
myRay.IsLocked = false;
