Change chart panel back color and bar color for a previous bar.

[ackchan]

I can't find a way to change the chart panel color for a previous bar on a custom indicator I developed. I know the Backcolor = Color.Salmon; command changes the color of the current bar to Salmon but is there a way to do this for a previous bar?

Similarly is there a way to change the colour of a previous bar on the chart panel. I know the Barcolor =Color.Salmon can only change the color of the current bar.

Appreciate any help.

Hello,

Please go here:

...and copy and paste in the example section.

I looked at the link posted. I guess that means that it's not possible to change for a previous bar then, only possible for the current bar? Actually what I want to do is to make known visibly in a chart, the previous bar selected by the NinjaTrader Swing().SwingHigh() function. Is there a way to do this?

Hello,

The swing indicator won't work for this very well. Its values change retroactively. It takes a bit more programming to make that work.

How to backcolor of the previous bar in a strategy

Hi!
I want to backcolor the previous bar in a strategy.

if (true)
  {
       set the backcolor of the previous bar to lime green
  }

How can I do this?

Since there isn't any bars_ago option in the Backcolor property, I'v tried to use the DrawRegion() method, But it don't woks the way I hoped.

_zero.Set(0);

if (true)
   {
        DrawRegion("Mytag" + CurrentBar, CurrentBar-1, CurrentBar, _zero, 100000, Color.Empty, Color.Lime, 1);
   }

(This doesn't paint at all and there is no error message.)

Do you have any suggestion how I can backcolor the previous bar?

Have you tried something like this snippet below?

 
if (CurrentBar < 1) return;
 
DrawRegion("Region1", 1, 0, Low, High[1], Color.Black, Color.Blue, 5);

Correct is the BackColor call is for the current bar only, so this might provide a workaround.

For an unsupported method you could check into the CandleStickPattern indicator and how it visualizes the found patterns.
