Drawing a line....

[jed77]

Hello,

I want to develop a very simple indicator... But I cannot figure out how to do that....

It must be easy, but I'm stuck.

I just want to draw a vertical line on my chart x bars in the past....

Please, can you help me ?
Thank you very much.

Hi jed77,
You can use DrawVerticalLine() for your indicator, please see this link to its syntax - http://www.ninjatrader-support.com/H...ticalLine.html

Oh ! Thank you Bertrand.
It is working fine !
But now I'm stuck in another problem....
If I want to draw 2 lines ? I wrote that and the last one only appear on the chart...

            // To avoid the"index out of range" :
            if (CurrentBar < 20)
                     return;
            
            // Draws  vertical lines
            {
            DrawVerticalLine("myTag", 9, Color.Black);
            DrawVerticalLine("myTag", 14, Color.Red);
            }

Thx !

Just use another tag name for the second line, like myTag2...otherwise you will just 'grab' the old line and modify it instead of creating a new one.

you are welcome jed77, stupid is the wrong word, it's called learning

[jed77]

Thank you Bertrand You are very kind !

Ok, the lines are plotted on the price panel.
Is it possible to plot the lines on an indicator window ? Overlaying a Stochastic as an example ?
Thx

If you want to draw objects elsewhere you need to set DrawOnPricePanel = false.
