How to capture a mouse click's location on chart in NT7.

April 20th, 2017, 10:07 PM

Hello.

THis is likely something that not too many people have experience doing in NT.

But what I am looking to do, is have an indicator, that once ENABLED(via button somewhere in the chart), that will capture the x/y position upon a mouse-click.

I'd then translate that into price and time.

I am thinking the ENABLE button would have to disable the native chart controls so that the clicking can occur. As I will be doing some reporting both onto the chart and to the output window.

But the most important things that I don't know how to do in NT7 are:

Create a button that will enable/disable the script while it is loaded onto a chart
Capture the X/Y position on mouse-click once that button is enabled

Just checking to see if anyone has done anything similar to this?

Thanks

You may want to use something like this :

In the function that gets triggered when clicking the toolbar, you then can toggle a flag to stop your script.

Code

private ToolStripButton _myButton;

private void add_Button()
{
	try
	{
		ToolStrip toolStrip = ((Control)this.ChartControl).Controls["tsrTool"] as ToolStrip;
		if (toolStrip != null && toolStrip.Items.ContainsKey("btnMY") )
		{
			toolStrip.Items.RemoveByKey("btnMY");
		}

				
		if (toolStrip != null && !toolStrip.Items.ContainsKey("btnMY"))
		{					
			this._myButton = new ToolStripButton("butMY", (Image)null, new EventHandler(this.myButton_Clicked), "btnMY");
			this._myButton.CheckOnClick = true;
			toolStrip.Items.Add((ToolStripItem)this._myButton);
		}
		else
		{
			if (toolStrip.Items.ContainsKey("btnMY") )
			{
				//Print("Button btnMY exists");
			}
	        }
					
		if (this._myButton == null)
			return;
				
		this._myButton.Checked = ;
	}
	catch
	{
	}
}



private void remove_Button()
{
	ToolStrip toolStrip = ((Control)this.ChartControl).Controls["tsrTool"] as ToolStrip;
	if (toolStrip == null || !toolStrip.Items.ContainsKey("btnMY"))
		return;
	toolStrip.Items.RemoveByKey("btnMY");
			
}

private void myButton_Clicked (object sender, EventArgs e)
{
	// put your code here
}

protected override void OnStartUp()
{
	if (this.ChartControl == null )
	{
		return;
	}
	this.add_Button();
}

protected override void OnTermination()
{
	
	this.remove_Button();			
}

I wrote some code for you - add button to tool strip, if button is enabled and you clicked on chart, indicator prints info about clicked coordinates to output window. If you like print or draw some info into chart, input your code into Plot() function.

Wow sir!!!

That is EXACTLY what I needed. I should be able to do whatever I need to with that script.

These type of things I imagine not many of us have experience doing, so this helps out a ton.
