Reading a horizontal line "Y" value

Same Line on price Panel

Hi again Joydeep. I have another question on these lines I'd appreciate some help. If you look at the attached chart you will see the green line DS2 in Panel2. I get this line as follows:

//Level 2 support
            
            if (DrawObjects["DS2"] != null && DrawObjects["DS2"].DrawType == DrawType.Ray)
            {    
            IRay    alertLineDS2    = null;
            IDrawObject        drawAlertLineDS2    = DrawObjects["DS2"];
            if (drawAlertLineDS2 != null && drawAlertLineDS2.DrawType == DrawType.Ray)
            alertLineDS2 = (drawAlertLineDS2 as IRay);
            
            lineTargetDS2 = showtargetoneDS2 ? Instrument.MasterInstrument.Round2TickSize(alertLineDS2.Anchor1Y) : targetoneDS2;
            DrawOnPricePanel = false;DrawText("tag22", false,"DS2", -10,lineTargetDS2, -10,Color.White,new Font("Arial", 7, FontStyle.Bold),StringAlignment.Center, Color.Lime, Color.Black, 10);DrawOnPricePanel = true;
            alertLineDS2.Pen.Color = Color.Lime;
            alertLineDS2.Pen.Width = 2;
            alertLineDS2.Pen.DashStyle = DashStyle.Dot;
            } 

Once I manually insert DS2 ray I then draw another corresponding ray PS2 on the price panel. What I'd like to do now is automatically draw a PS2 Ray on the price panel without me having to manually draw it. So basically once I draw the DS2 Ray it should automatically draw the PS2 at the low of the bar on the price pane. When I move the DS2 line somewhere else then the PS2 line should also move.

Any ideas on this one?
Thanks in advance
DJ

Hello djkiwi,
After you have drawn the DS2, simply draw the ray programitaccly taking reference of the alertLineDS2's x y value.

// add this line below your code 

DrawRay("ray", alertLineDS2.Anchor1BarsAgo, Low[alertLineDS2.Anchor1BarsAgo], alertLineDS2.Anchor2BarsAgo, Low[alertLineDS2.Anchor1BarsAgo], Color.Blue);

Please let me know if I can assist you any further.

Draw Line

Hi Joydeep, thank you very much for that. In fact I've been messing around with this piece of code for the last few hours trying to make it work.

Cheers

Chart Lines moving

Thanks Joydeep. There is another issue I'd appreciate some help on this chart. Currently I am drawing lines on the bottom panel which is now reflected on the top panel based on the code you gave me. The only problem I'm finding is the lines on the bottom panel keep moving when I log back in or sometimes press F5 etc. The chart is obviously refreshing and changing the position based on new data. If you look at the first chart it all looks ok where I drew the line. The second chart in panel 2 the lines have moved away from the values I want so I have to keep moving them up and down where they should be. I use the actual numerical values on the chart in indicators so it is important the line are at the right place

So is there a way to stop this happening. i.e automatically keep anchoring the lines on panel 2 to the the nearest high or low or stop the chart repositioning in the panel.

Thanks in advance
DJ

Hello DJ,
Unfortunately you cannot change the x values of the manually drawn lines programmatically.

Draw Rectangle

Hi Joydeep unfortunately I have to seek your services yet again

I'm having some difficulty with drawrectangle. If you look at the attached chart. I have drawn the rectangle using the following code:

DrawRectangle("upper2", false, 500,abovevalue1, -25,abovevalue2, Color.Transparent, Color.Red, 3); 

The problem is the 500 number. I want to draw the rectangle from the first bar of the chart to the end. The 500 places it where it is now. If I put in 2000 instead of 500 I get this error in the log saying drawrectangle: startbarsago out of valid range and nothing is drawn. So the question is how do tell it to draw the rectangle from the first bar o the chart to the last bar of the chart?

Thanks in advance

DJ

Please use this code to draw the rectangle from the first bar.

DrawRectangle("upper2", false, CurrentBar,abovevalue1, -25,abovevalue2, Color.Transparent, Color.Red, 3);

Draw Locked

Thanks Joydeep. I did try that before and it didn't work. Seems to work ok now though. I have another one here though. I'm using this code to unlock the Ilines which works well:

foreach (IDrawObject draw in DrawObjects)

{
draw.Locked = false;
}

The problem is I'm not sure how to unlock a normal drawobject for example this line:

DrawRay("PS1", false, alertLineDS1.Anchor1BarsAgo, Low[alertLineDS1.Anchor1BarsAgo], alertLineDS1.Anchor2BarsAgo, Low[alertLineDS1.Anchor1BarsAgo], Color.Cyan,DashStyle.Dot,2); 

I tried just drawobject but did not work.

Thanks in advance
DJ

Hello DJ,
You can lock/unlock a draw object from the below code:

IRay ray = DrawRay("PS1", false, alertLineDS1.Anchor1BarsAgo, Low[alertLineDS1.Anchor1BarsAgo], alertLineDS1.Anchor2BarsAgo, Low[alertLineDS1.Anchor1BarsAgo], Color.Cyan,DashStyle.Dot,2);  

ray.Locked = false; //unlock the ray

Please let me know if I can assist you any further.
