can`t detect manually brushed rectangle

[Dert66]

Hi
I can`t detect manually brushed rectangle by this code:

foreach(IDrawingTool myDrawObject in DrawObjects) {
DrawingTools.Rectangle myRectangle = myDrawObject as DrawingTools.Rectangle;
if (null != myRectangle) Print("Found a rectangle");
}

How can i detect it and get prices and times of rectangle?

Hello Dert66,

Thanks for your post and welcome to the NinjaTrader forums!

Here is a simple example of how to check for draw objects:

 foreach (DrawingTool draw in DrawObjects.ToList())
              {
                Print (draw.Tag+"  "+draw.Description+" "+draw.DisplayName+" "+draw.Id+"  "+draw.MaxValue+"  "+draw.MinValue);
            }

You can expand the print example to check the bool state of draw.IsUserDrawn.

The help guide provides further examples of detecting and changing draw objects here: https://ninjatrader.com/support/help...rawobjects.htm

Hello Dert66 ,

Thanks for your post.

Here is an example:

            foreach (DrawingTool draw in DrawObjects.ToList())
              {
                if (draw is DrawingTools.Rectangle && draw.IsUserDrawn)
                {                    
                    DrawingTools.Rectangle mycopy = draw as DrawingTools.Rectangle;

                    Print (mycopy.Tag+"  "+mycopy.StartAnchor.Time+"  "+mycopy.StartAnchor.Price+"  "+mycopy.EndAnchor.Time + "  " + mycopy.EndAnchor.Price);
                }
            }

Hello Dert66,

Thanks for your reply.

You are conditionally looking for rectangles on Bar 515, if you remove that condition does your code then work?

[Dert66]

No.........

Hello Dert66,

Thanks for your reply.

I've created a short video demonstrating working code here: https://Paul-ninjaTrader.tinytake.co...Ml8xMTEwNjQ4MQ

I suspect that if you drew a new rectangle that it would be detected, otherwise I would suggest adding the && draw.IsUserDrawn as shown in my code.

Thank you, Paul H!!
after "reload all historical data" - its OK!

[Dert66]

for the condition to work I have to re-draw the rectangles
if(draw is DrawingTools.Rectangle && draw.IsUserDrawn){}
how to detect rectangles drawn before adding an indicator?

Hello Dert66,

Thanks for your reply.

With reference back to the code/indicator have shown, if added to a chart with existing rectangles, on each OnBarUpdate, the existing rectangles are found and any new one drawn after it is added as well.

I am not sure i understand what you mean by, "how to detect rectangles drawn before adding an indicator?"

[Dert66]

No this condition:

foreach(DrawingTool draw in DrawObjects.ToList()) {
if(draw is DrawingTools.Rectangle && draw.IsUserDrawn){Print("detect rect");}
}

detect rectangles only if indicator are loaded before I drawing rectangles
but
This code:

foreach(DrawingTool draw in DrawObjects.ToList()) {
if (draw.Name == "Rectangle" && draw.IsUserDrawn) {
     foreach(ChartAnchor myAnchor in draw.Anchors) {
                     Print("Rect_ancor"+myAnchor);
    }
}

detect ancors of rectangle

if indicator are loaded before AND After I drawing rectangles
