Paint Bar help.

[davidjrjr]

I was wondering if anyone knew of the proper code for an indicator that will do this.

If current bar close is up and previous bars close was up paint current bar Blue
Other wise paint bar Cyan (as chosen in data series)

If current bar close is down and previous bars close was down paint current bar Red
Other wise paint bar Pink (as chosen in data series)

Sorry i have no code writting ability.

I guess you could call this indicator (Heat Bars).. As you get successive closes in on direction it paints bar a brighter color if not it paints bar chosen in the data series for up and down bars.
I would use this at support/resistance as a trigger to enter on a range chart..

Thanks for any help or direction

Hello davidjrjr,

Thank you for your post.

The code would be the following:

			if(Close[0] > Open[0] && Close[1] > Open[1])
				BarColor = Color.Blue;
			if(Close[0] < Open[0] && Close[1] < Open[1])
				BarColor = Color.Red;

For information on the BarColor please visit the following link: http://www.ninjatrader.com/support/h...7/barcolor.htm

Please let me know if you have any questions.

Ok Thanks
I'll give a try.
I should be able to copy and paste into new ind script?

Hello davidjrjr,

Thank you for your response.

That is correct, but paste it into the OnBarUpdate() method.

[davidjrjr]

Sorry, seems I am doing something wrong.

Here is where i am at but it will not compile.

protectedoverridevoid OnBarUpdate()
{
Add(new Plot(Color.FromKnownColor(KnownColor.Orange), PlotStyle.Line, "Plot0"));
Overlay = false;
}
///<summary>
/// Called on each bar update event (incoming tick)
///</summary>
protectedoverridevoid OnBarUpdate()
{
if(Close[0] > Open[0] && Close[1] > Open[1])
BarColor = Color.Blue;
if(Close[0] < Open[0] && Close[1] < Open[1])
BarColor = Color.Red;
// Use this method for calculating your indicator values. Assign a value to each
// plot below by replacing 'Close[0]' with your own formula.
Plot0.Set(Close[0]);

Hello davidjrjr,

Thank you for your response.

Please send me a screenshot of the error with the name and description fields clearly readable.

To send a screenshot press Alt + PRINT SCREEN to take a screen shot of the selected window. Then go to Start--> Accessories--> Paint, and press CRTL + V to paste the image. Lastly, save as a jpeg file and send the file as an attachment.

Hope I did this right,, thanks

Hello davidjrjr,

Thank you for your response.

You have two OnBarUpdate() methods defined in your code and no Initialize() method. Your HEATBARS indicator code should reflect the code listed below. You can find this indicator attached to this post as well. To import please first go to Tools > Edit NinjaScript > Indicator > select the HEATBARS > Delete > then Cancel > then download the attached .zip file to your Desktop > then go to File > Utilities > Import NinjaScript and select the HEATBARS.zip file on your desktop.

Sorry, seems I am doing something wrong.

Here is where i am at but it will not compile.

protectedoverridevoid OnBarUpdate()

BarColor = Color.Red;
// Use this method for calculating your indicator values. Assign a value to each
// plot below by replacing 'Close[0]' with your own formula.
Plot0.Set(Close[0]);

It will not compile, or it will not color the bars? Which.

[davidjrjr]

Thanks,
But,, It doesnt to seem to work or any thing being indicated.

It downloaded and imported fine. I added it to chart assigned it to price but no
color changes.

Sorry for being so much bother..

Am i missing something?

[Harry]

There is a small bug in the Heat Bars, please replace OnBarUpdate() with

[COLOR=Blue]protected override void[/COLOR] OnBarUpdate()         
{             
     [COLOR=Navy][COLOR=Blue]if[/COLOR]([/COLOR]CurrentBar < 1)  [COLOR=Green]// necessary addition, otherwise the indicator will not work[/COLOR]
          [COLOR=Blue]return[/COLOR];
    [COLOR=Blue] if[/COLOR](Close[0] > Open[0] && Close[1] > Open[1])                 
          BarColorSeries[-Displacement]  = Color.Blue;   [COLOR=Green]// recommended  [/COLOR]        
     [COLOR=Blue]if[/COLOR](Close[0] < Open[0] && Close[1] < Open[1])                 
         BarColorSeries[-Displacement]  = Color.Red;     [COLOR=Green]// recommended[/COLOR]
}
