Draw text on 2 panels from same indicator

[RedDuke]

Hello,

I am ware that this setting DrawOnPricePanel = false; will allow my indicator to draw on non price panel. I need ability for 1 indicator to draw on 2 different panels at the same time. I found this post from Ninja Staff from about 2 years ago:

"It is not possible for a single indicator to draw objects on multiple panels.
It is necessary to split the drawing calls into multiple indicators."

Is this still the case?

Thanks,

Hello RedDuke,
I believe its not possible to add multiple panels from within an indicator as of now so we have to split the indicators for such cases. We can't draw or plot on multiple panels simultaneously.

Hello RedDuke,

Thanks for your post.

Yes, it is possible and there are some limitations however first let's be clear on what a Draw Object is as there can be confusion. To keep it simple, Draw Objects are created by the use of Draw statements. Plots are not considered draw objects. So it is correct that plots can only be sent to one panel and one script can only send plots to one panel. So in the case of plotting in two panels, yes that would require two scripts.

Draw objects can be sent to the price panel and/or the indicator panel when the script creates as an indicator panel. If the script is a price panel only, then it cannot send draw objects to an indicator panel it did not create.

Also, there is this limitation in the use of DrawOnPricePanel which you must be aware of: Warning: This property should ONLY be set from the OnStateChange() method during State.SetDefaults. Dynamically using DrawOnPricePanel in an indicator outside of State.SetDefaults may show issues when working with that indicator through a hosting strategy via AddChartIndicator(). Reference: https://ninjatrader.com/support/help...pricepanel.htm

So if your indicator is ever added to a chart by AddChartIndicator() in a strategy, it may not perform as expected regarding the draw objects.

I've attached an example script you can replicate that shows creating an indicator panel (IsOverLay = false) and assigning a plot value to plot in the indicator panel. Two Draw.Dot() statements, every 100 bars, are used to show that you can draw on the price panel and then draw on the indicator panel by flipping the state of DrawOnPricePanel. They draw at the same bar/time but this does not mean they have to be drawn on the same bar/time.

Hello Paul,
Thanks for the info.

Hi Paul,

I tried this with Draw.Text but in both below examples text got printed on price panel:

Draw.Text(this, "A4", true, "A", 0, Low[0]-TickSize*3, 0, Brushes.Blue, textFont, 0 , Brushes.Black, Brushes.Black, 0);
Draw.Text(this, "A5", true, "A", 0, High[0]+TickSize*3, 0, Brushes.Blue, textFont, 0 , Brushes.Black, Brushes.Black, 0);

DrawOnPricePanel=false;

Draw.Text(this, "A6", true, "B", 0, Lows[2][0]-TickSize*3, 0, Brushes.Blue, textFont, 0 , Brushes.Black, Brushes.Black, 0);
Draw.Text(this, "A7", true, "B", 0, Highs[2][0]+TickSize*3, 0, Brushes.Blue, textFont, 0 , Brushes.Black, Brushes.Black, 0);

DrawOnPricePanel=true;

Any idea what I am doing wrong?

Thanks,

Hello RedDuke,
Try this:
Draw.Text(this, "pp", "test", 0, Low[0] - 5);
DrawOnPricePanel = false;
Draw.Text(this, "ip", "test", 0, 0);
DrawOnPricePanel = true;
pp should draw on price panel & ip should draw on indicator panel. I am assuming you've set DrawOnPricePanel = true; so you're basically resetting this property after each text command.
Hope it helps!

Hi S. Kinra,

It did not work. But I think I know why. I have 2 price Panels with different time series on the same instrument. Essentially I want indicator that runs on Price Panel 1 draw something on Price Panel 2.

Thanks,

Hello RedDuke,
I haven't yet worked with 2 price panels but surely give a try, update you if I get something, I am sure Paul will guide in a better way for now.

Hello RedDuke,

Thanks for your reply.

An indicator can draw in its own indicator panel and/or the related price panel through the demonstrated use of DrawOnPricePanel.

There would be no means to draw from one price panel to another price panel.

I understand. Thank you very much for explaining.
