indicator with 1min & 5min volumes

[mate41]

Hi,
i've some problem finish the plot section/

//variables
private DataSeries myDataSeries;
// initialize
Add(new Plot(new Pen(Color.Red, 2), PlotStyle.Line, "VolumeFast"));  // 1min plot
Add(new Plot(new Pen(Color.Blue, 2), PlotStyle.Line, "VolumeSlow"));  // 5min plot
Add(PeriodType.Minute, 5);
// OnBarUpdate
VolumeFast.Set(Volumes[0][0]);    // plot the 1min volume
VolumeSlow.Set(Volumes[1][0]);    // plot the 5min volume

It plots a "ladder line".
How can i plot the 2 lines: 1 red, 2th blue.
Thanks

Hello mate41,

There are two plots that are added as line plots. These will connect each point and will not be straight. This type of plot is the type of plot used for the SMA.

I am unsure of the ladder line you are describing. Can you include a screenshot of this?

To send a screenshot with Windows 7 or newer I would recommend using Window's Snipping Tool.

Alternatively 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 CTRL + V to paste the image. Lastly, save as a jpeg file and send the file as an attachment.

Also, in the script you are setting VolumeFast and VolumeSlow. Are these public plots declared in the properties region of the script?
May I see the code for this as well?
(Does your script compile without error?)

I've added a screenshot in 1st post.

[Browsable(false)]    // this line prevents the data series from being displayed in the indicator properties dialog, do not remove
        [XmlIgnore()]        // this line ensures that the indicator can be saved/recovered as part of a chart template, do not remove
        public DataSeries VolumeSlow
        {
            get { return Values[0]; }
        }

        [Browsable(false)]    // this line prevents the data series from being displayed in the indicator properties dialog, do not remove
        [XmlIgnore()]        // this line ensures that the indicator can be saved/recovered as part of a chart template, do not remove
        public DataSeries VolumeFast
        {
            get { return Values[0]; }
        }

There is no more code than indicated.

Hello mate41,

Public DataSeries are declared in the Properties region.

Please open the MACD indicator and view lines 79 through 84 where a public DataSeries is declared to return the internal plot created by NinjaTrader.

Tools -> Edit NinjaScript -> Indicator... -> MACD -> OK
Click the plus to expand #region Properties
View lines 79 to 84

This makes the plot public so that it can be accessed from outside of the script. In the MACD likes 79 through 84 is how the Avg plot is created. This is so that Avg.Set() can be used instead of Values[1].Set().

In your script, both VolumeFast and VolumeSlow are returning Values[0]. This means that Values[1] is never being set in your script.

Thus only one plot will ever appear.

I believe you intended for VolumeSlow to return Values[1] as this is the second plot.

Below is a link to the help guide on Values.

With your screenshot in post 1 I am not understanding how this is a ladder. Can you further explain how the plot line is a ladder?

            get { return Values[0]; }

        public DataSeries VolumeFast
        {
            get { return Values[0]; }
        }

Sorry, found the problem if it is right:

 get { return Values[0];

corrected with :

 get { return Values[1];

now there are 2 lines, a red and a blue.

After a cleanup the indicator don't display the lines anymore.
Here is the code. What could be wrong ?
thanks

Hi mate41,

Are you getting any errors in the Log tab of the Control Center?

I see that you have a secondary series added to your script of 5 minutes.

Remember that if your second data series is 5 minutes and your primary data series is a 1 minute. There will be 4 - 1 minute bars before there is any 5 minute bar.

In other words, are you calling an index that doesn't exist?
(Are you trying to call the volume of a 5 minute series before its been 5 minutes?)

Try adding a check to your code that both series have at least 1 bar.

Thanks Chelsia,
with the cleanup, I removed mistakenly the "CurrentBar control of 5 OnBarUpdate's".
