Get coordinates from Rectangle on chart

[stoxos]

Hello i want to create a volume profile based on ninjatrader sample VP. But i want to get y x or price and time coordinates from a rectangle that i draw with a specified name lets say "VPR".

I already know that onRender can get x y from as example

 xCoordinate = chartControl.GetXByBarIndex(ChartBars, 100);

and i also try to give a parameter like a string which would be the name so search chart for the object with the specified name and return me the value but no luck.

In MQL4 we had something like ObjectGet();

What is the equivalent in Ninjascript?

Thank a lot !

Hello stoxos,

Thank you for your response.

Is the rectangle manually drawn or drawn in code?

You can loop through the draw objects with the example at the following link: http://ninjatrader.com/support/helpG...rawobjects.htm

I look forward to your response.

Hmm thank you for your response, But DrawObjects works on OnBarUpdate() i have my code on OnMarketData because i use tickreplay. So if i use it on OnBarUpdate() there are two problems:
1) I need open markets or market replay
2)The indicator will update each new bar which is a problem since i want the user to be able to use the lines or rectangle object anytime he wants and almost instantly get his result on chart.

For the time i left rectangle and i try to create a volume profile with range between two vertical lines. I want to take the time from each of those lines for the profile calculation start and end.

So how i can find the lines from OnMarketData and take there values of datetime?

P.S. even on the example i so that i can lets say change each color or width of the object but how i get the values?

  // An alternative approach to find the draw object by a tag
  if (DrawObjects["someTag"] as DrawingTools.Line != null)
  {
    // Do something drawing tool line
  }

Thank you!

Hello stoxos,

Thank you for your response.

You can loop through the objects in OnMarketData as well just ensure you check that ChartControl is not null: http://ninjatrader.com/support/helpG...artcontrol.htm

Depending on the object you pull from the loop you will want to refer to it's properties directly through IDrawingTool: http://ninjatrader.com/support/helpG...rawingtool.htm

Please let me know if you have any questions.

Ok i try to understand this is an example i create a text and i get its value from "Anchor.Time" and i also i can print the value!

			Text myText = Draw.Text(this, "tag", "test", 0, High[0]);     
			  
			  if(myText != null)
			  {           
			    Print(myText.Anchor.Time); 
			  }

But on VerticalLine there is no "Anchor" there is "Anchors". And then when i try to insert the following code

VerticalLine myLine = Draw.VerticalLine(this, "tag1", 10, Brushes.Black);

my Volume profile doesnt draw at all. So it works with text object but not with vertical line. I dont know why. I tried also onRender and onBarUpdate still the same happens my code is the same as ninjatrader volume profile sample.

Can you provide please an example of code where you get from a vertical line the value of time ? Cause i have messed up!


P.s. i dont need to loop since i have the specified tag of the object

Thank you!

Thank you for your help but it so not what i am looking for, i need to get the value from the object not the mouse.

Thank you

//Create a class of rectangle parameters

public class PatternTextLocation
{
public DateTime STARTTIME;
public DateTime ENDTIME;
public double STARTYCOORD;
public double ENDYCOORD;




public PatternTextLocation(DateTime tStartTime,tEndTime)
{
STARTTIME = tStartTime;
ENDTIME = tEndTime;
etc, etc.

}

}


//create a list

private List<PatternTextLocation> PatternTextTimeLocation; // an array of timestamps when the rectangles were printed historically or live




in OnBarUpdate()

{


if(this.PatternTextTimeLocation == null)
this.PatternTextTimeLocation = new List<PatternTextLocation>();

// this is the line you need when adding you object class in you logic

this.PatternTextTimeLocation.Add(new PatternTextLocation(parameter in your class));

Hello stoxos,

Thank you for your patience.

Below is an example of pulling the time. I use a loop but the same concept applies to the object.

			foreach (DrawingTool draw in DrawObjects)
			{
				if (draw is VerticalLine && draw.Name == "Vertical Line")
				{
					VerticalLine vLine = draw as VerticalLine;
					Print(vLine.StartAnchor.Time);
				}
			}

Please let me know if you have any questions.

I used StartAnchor.Time. It gets the job done. Thank you a lot my friend for your answer and time!

BINGO!! Thats it "StartAnchor". It just is not listed when i press the dot after the line thats why i couldnt find it.

Thank you for the great support again!
