how do I create and display on a chart a line parallel to my custom indicator?

Hello joemiller,

Thank you for your post.

Are you looking for a line plotted at a set number from the original plot?

Can you provide a screenshot of a chart with an example of what you are looking for?

I look forward to your response.

I want to draw a line parallel [constant displacement] to the red indicator line displayed in the attachment.
perhaps is can best be done by a separate indicator, or by more code in the same indicator, etc?

[NinjaTrader_PatrickH]

Hello joemiller,

Thank you for your response.

It may be easier to add the additional plot to the current indicator.

You could displace the line using + or - a number:

myCustomPlot.Set(joeXXOindicator()[0] + myDisplacement);

You can find a reference sample on plots at the following link as well: http://www.ninjatrader.com/support/f...ead.php?t=3227

Please let me know if I may be of further assistance.

I tried several things with no success [eg]

Add(new Plot(new Pen(Color.Red, 2), "PlotXXO_1")); //initialize region
PlotXXO_1.Set(joeXXOindicator()[0] + 0.00500);//onbarupdate region

I have no idea how to make it work. please advise.

Hello joemiller,

Thank you for your update on this item.

Please attach the indicator to your response so I may provide an example of how to set this plot.

[joemiller]

indicator is attached.

Did you define the Plot's access properties?

[joemiller]

I don't have a clue what an access property is. Sounds like a good lead, which I would pursue if I were not waiting for Patrick's reply.

thanks for the response.

Hello joemiller,

Thank you for your response.

Koganam was correct, the plot needs to be defined in the properties:

        #region Properties
        [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 PlotXXO
        {
            get { return Values[0]; }
        }
		
       [B] [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 PlotXXO_1
        {
            get { return Values[1]; }
        }[/B]

In addition, adding the value of 0.005 may not even be noticeable on some instruments. I tried this on the ES and I had to expand the chart on the y-axis to even see the new plot. I tried the following and received more desirable results no matter the instrument:

PlotXXO_1.Set(XXOpen + (1*TickSize));

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

Please let me know if I may be of further assistance.

thanks Patrick & Koganam
worked like a charm

[joemiller]

In the initialize region I added the statement
‘Add(new Plot(new Pen(Color.Black, 1), "PlotXXO_1"));’
patterned after
‘Add(new Plot(new Pen(Color.Red, 2), "PlotXXO"));’

hoping that it would generate the parallel line in a black instead of a red color. However it did not work. I blindly tried several fixes without success. Should I maybe have something additional in the properties region or elsewhere?

[NinjaTrader_PatrickH]

Hello joemiller,

Thank you for your response.

Please remove the indicator from your chart and then add it back, this should correct the plot.

[joemiller]

thank you Patrick
it worked

I cannot get the following DrawLine to work.

// ..............(.... tag ,..... auto, ...start, starty, end, endy,.. color , ...........dash ,.. width)
// .................................scale... bars.............bars............................. ......style , ..pixels
// .............................................. ago.............ago
//DrawLine("PlotXXO", false,.... 10,... 1.33,.... 0,.. 1.33,.. Color.Red, DashStyle.Dot, 2);


It has been placed in region OnBarUpdate as follows
PlotXXO_1.Set(XXOpen + (25*TickSize));
DrawLine("PlotXXO", false, 10, 1.33, 0, 1.33, Color.Red, DashStyle.Dot, 2);

The following statements are in the initialize region:
Add(new Plot(new Pen(Color.Red, 2), "PlotXXO"));
Add(new Plot(new Pen(Color.Black, 0), "PlotXXO_1"));

starty and endy values = 1.33 are for test and are for the forex euro dollar/us dollar currency pair.

A listing of the indicator is attached in post #7.

I’m thinking that it may be a simple matter of syntax or form such as the wrong tag?
I’m aware that clarification to all this will probably be necessary.
