ACSIL: How do I get the time value of a Vertical line that I have drawn on the chart

yonatan · May 27th, 2012, 06:21 AM

I want my study to use the Time value of a Vertical line that I have manually drawn on the chart and the Price value of a Horizontal line that I have manually drawn on the chart. Any idea how I can get those values ?

You can do like this:

Code

#include "C:\Sierrachart\ACS_Source\sierrachart.h"

SCDLLName("GetLineValue")

SCSFExport scsf_GetLineValues(SCStudyInterfaceRef sc)
{	
	if (sc.SetDefaults)
	{
		sc.GraphName = "GetLineValues";		
		sc.StudyDescription = "";		
		sc.GraphRegion = 0;		
		sc.FreeDLL = 1;		
		return;
	}


	s_UseTool line;
	
	if (sc.GetChartDrawing(0, DRAWING_HORIZONTALLINE, line, 0))
 	{

		SCString str;	
		float val = line.BeginValue;
		str.Format("Horizontal line, value: %f",val);
 		sc.AddMessageToLog(str, 0);
 	}

	if (sc.GetChartDrawing(0, DRAWING_VERTICALLINE, line, 0))
 	{

		SCDateTime dt = line.BeginDateTime;
		int yy,mm,dd,h,m,s;
		dt.GetDateTimeYMDHMS(yy, mm, dd, h, m, s);
		int barindex = line.BeginIndex;
		SCString str;	
		str.Format("Vertical line, barindex:%d, time: %d:%d",barindex,h,m);
 		sc.AddMessageToLog(str, 0);
 	}
}

Awesome ktrader, much thanks.

Now, if I have a few Horizontal and Vertical lines on the chart and I wish to retrieve those values for a specific line am I correct by assuming that I will have to create this specific line with an ACSIL code and assign to it a "LineNumber" and then I will be able to get its values with sc.GetUserDrawingByLineNumber() ?

Yes, you can do that. Or if you know how many lines you add you can utilize they are numbered sequentially so:

first horizontal line you add (manually on the chart) you get by:

sc.GetChartDrawing(0, DRAWING_HORIZONTALLINE, line, 0)

second one with
sc.GetChartDrawing(0, DRAWING_HORIZONTALLINE, line, 1)

first vertical: sc.GetChartDrawing(0, DRAWING_VERTICALLINE, line, 0)
second vertical: sc.GetChartDrawing(0, DRAWING_VERTICALLINE, line, 1)

Great. Thanks again ktrader. This was very very helpful.

I'm auto-drawing ellipses, I have:

s_UseTool EllipseTool;
EllipseTool.AddMethod = UTAM_ADD_OR_ADJUST;

and when the tool gets drawn I set:

int uid = rand();
EllipseTool.LineNumber = uid;

The Ellipse drawing starts and then a couple of bars later, when certain parameters are met, I want to "close" the Ellipse.
How do I call *that* particular Ellipse?

I have this, and works about 90%:

if (sc.LineExists(sc.ChartNumber, uid)
{
blah;
}

many tools are drawn and closed as expected, however one seems to be hanging from the beginning of the chart to the current index. Which leads me to believe the code has missed this particular LineNumber, or something. Which then leads me to believe that I need more control and how to call each generated Ellipse. Any ideas?

Hi Funk101, I think you better post this in the main sierra charts programming forum (Sierra Chart Programming - Big Mike's Trading Forum) so it will not hide here in this thread.
