Draw Vertical Line

[jjthetrader]

Hey guys,

I'm looking to have a vertical Line drawn between a high and a low in an indicator.
In this example from the help file I get 10 which is bars back. But I'm looking to connect the high and the low for the current bar with a vertical line so it looks similar to the price bar.

DrawVerticalLine("tag1", 10, Color.Black);

Could I get some help with setting the start and stop of the line?

In english I'd like the logic to be: Draw vertical line starting here and ending here for the current bar.

Thanks a lot.

DrawLine("Tag1", 0, highValue, 0, lowValue, Color.Blue)

Thanks Ray, Does that go in OnBarUpdate()?
I put it in there with the proper value's but it didn't draw anything.
thanks

Yes, in OnBarUpdate()

Thanks for the help Ray,


protectedoverridevoid OnBarUpdate()
{
// Use this method for calculating your indicator values. Assign a value to each
// plot below by replacing 'Close[0]' with your own formula.


Hi.Set(ValueHi());
Lo.Set(ValueLo());
DrawLine("Tag1", 0, ValueHi(), 0, ValueLo(), Color.White);
}

Is this enough to plot the line that I asked about in the previous question or do I need to reference that tag somehow?
thanks

Likely, just try it out and test it.

Hey Ray, That peice of code doesn't give me a line. For hi and low value I also just put in a static number to make sure it wasn't my calculations but no go.
Any suggestions? Do I need anything in Initalize()?
thanks for the help.

I will look into it, it should work.

This works for me:

DrawLine("Tag1", 0, High[0] + 4 * TickSize, 0, Low[0] - 4 * TickSize, Color.Red);

There is likely something else wrong in your script that you would have to debug.

I appreciate your tiem with me Ray. Your code does work for me but it plots the line on the price panel. I would like the line drawn in the indicator panel. How can I modify that?
thanks

In the Initialize() method, include the following line:

DrawOnPricePanel = false;

Awesome Ray! It worked!!!

One more dilema for you. How can I get that line to stay and not just paint on the current bar. I'd like it to paint on the current bar of course but I'd also like it to stay when the bar is finished forming if possible.
thanks.

Then you have to provide a unique tag name for each line.

Instead of "Tag1"

Use something like

DrawLine("Tag1" + CurrentBar, 0, High[0] + 4 * TickSize, 0, Low[0] - 4 * TickSize, Color.Red);

Ray, you are the f'n MAN!

Got it! I'm very appreciative for your time and expertise.
