Where do arrows go?

[henry.omd]

Hello, I wrote an indicator which has been working fine until now. I wanted to draw some arrows on the indicator.

The indicator basically does the following:

if(....) {
BackColor = Color.Red;
} else if(....) {
DrawArrowUp(CurrentBar.ToString(), 0, 0.9, Color.Green);
}

The background color works fine, but the arrows show up in the main (the price bar) rather than the separate plot area for my indicator.

How can I draw the arrows on the right plot?

In the Initialize() method you want to set DrawOnPricePanel to false.

Works beautifully!

Thanks Josh!

Now, if I can fix the min and max value of my indicator at -1 and 1, I would be golden. The only thing that sounds remotely promising is AutoScale = false, but documentation says it's for something else entirely, and indeed, on trial does not actually fix the min and max value of the y-axis--as one might have expected.

Gratefully,

Henry

Well what range of values is your indicator taking on right now?

[henry.omd]

Usually somewhere between -0.5 and 0.5

This indicator can theoretically go from -1 to 1, but usually stays between -0.5 and 0.5. NT is autoscaling my indicator chart, which is nice for the main price chart but not for my indicator...

You can try adding lines to your plots at -1 and 1. Just make the lines transparent.

Add(new Line(Color.Transparent, -1, "Lower"));

Brilliant! Simple and effective!
