How I can get Rectangle coordinates.

[_Roman]

Hello!
How I can get Rectangle coordinates.

    protected override void OnBarUpdate()
        {
            foreach (DrawingTool draw in DrawObjects.ToList()) // Iterate over all objects
            {
                if (draw is DrawingTools.Line)//Here is Truly working
                {               
                    // Indicates line Tag
                    Print("Find Line Object: " + draw.Tag);
                  }    

                if (draw is DrawingTools.Rectangle)//<-I need here choose object rectangle. Why not working this line?
                {               
                    // Indicates rectangle Tag
                    Print("Find Rectangle Object: " + draw.Tag);

                 //How I can get coordinates or Rectangle. I need rectangle coordinates.
                  double startY; //Start Y Value of Rectangle
                  double endY;  //End Y Value of Rectangle
                  double startDateTime; //Start Y Value of Rectangle
                  double endDateTime; //End Y Value of Rectangle

                 //Thank You Very Much
                  }    
            }
        }

Line:
if (draw is DrawingTools.Line)//Here is Truly working
Is working Perfect.
Why not working line:
if (draw is DrawingTools.Rectangle)//<-I need here choose object rectangle. Why not working this line?
How I can get Rectangle coordinates.
On the chart I have a plot same objects.
Thank You Very Much.

Hello _Roman,

Thanks for your post and welcome to the NinjaTrader Forums!

Here is a short example you can test with:

protected override void OnBarUpdate()
{
if (State != State.Realtime) return; // waits until real time connected then finds rectangle (only did for this test)

if (DrawObjects.Count > 0) // Make sure we have an objects first
{
foreach (DrawingTool draw in DrawObjects.ToList()) // Go through objects
{
if (draw is DrawingTools.Rectangle) // test to find rectangle
{
Print ("Tag name: "+draw.Tag); // priint tag name
DrawingTools.Rectangle temp = draw as DrawingTools.Rectangle; // create copy to get anchorpoints

Print("startY: " + temp.StartAnchor.Price);
Print("startX: " + temp.StartAnchor.Time);

Print("endY: " + temp.EndAnchor.Price);
Print("endX: " + temp.EndAnchor.Time);
}
}
}
}

Hello Paul, I tried this code and works perfect when I draw a rectangle in chart, but it is not working when an indicator draw this rectangle.

Any suggestion?

Thanks

Hello federicoo,

Thanks for your post.

I tested here with an indicator that draws (Yellow) rectangles and ran the code (that draws a red test rectangle) and was able to pick up all of the details for each rectangle.

Please see attached.




You might want to double click on the indicators rectangles to look in the drawing objects properties to see if there is any info that may be helpful.

Thank you Paul,

Please see the screenshot attached. May be the drawing type is not a rectangle. Could I retrieve with coding which is the drawing type of the ones made by the indicator from the chart?

Hello federicoo,

Thanks for your reply.

You might try:


foreach (DrawingTool draw in DrawObjects.ToList())
{
Print ("Tag: "+draw.Tag+" Descr: "+draw.Description+" DisplayName: "+draw.DisplayName+" ID#: "+draw.Id
+" MAXValue: "+draw.MaxValue+" MinValue: "+draw.MinValue+" UsrDrawn? ");
}

[federicoo]

Here is the output:

Tag: @RectArb_35 25,53 Descr: DisplayName: Rectangle ID#: d5059f32e1d541aa87112b193f032829 MAXValue: -1,79769313486232E+308 MinValue: 1,79769313486232E+308 UsrDrawn?

Thanks

The code is failing in this sentence:

if (draw is DrawingTools.Rectangle) // test to find rectangle

This sentence is never true, it is like there were not any Rectangle in chart.

Thanks

[federicoo]

And the rare thing here is that the drawing is described as a Rectangle using the script of post #8 in chart.

Hello federicoo,

Thanks for your replies.

I've tried to replicate your condition by drawing a global rectangle and running the code to obtain the rectangle values and have no problems in doing so.

Can you provide further information on what is drawing the rectangle in question?

[federicoo]

I think the problem is that the rectangles that draw the indicator are not globals. So, the script can't retrieve the information. I tried to do a manual rectangle in one chart, and then set this as global (checkin attach to all charts), and then I ran the script in the secondary chart where this rectangle is drawn and is the same situation, not working...

[federicoo]

so I think the indicator is hidden the rectangle anchors

Hello federicoo,

Thanks for your replies.

The tag name is preceded by the "@" symbol which indicates a global draw object. In my test here I created a global rectangle on one chart and then on a different chart (of the same instrument) and ran a script that produced its own rectangle and then read all of the rectangles on the chart. The script was able to read both local and global rectangles.
