Get Line Properties as input for indicator

[nandhumca]

I am developing an indicator to draw custom lines based on some condition. To draw the line , I want to get below properties from user. Do I need to get all one by one or is there any input type called Line available to collect all as group ? Kindly share your input.

Color
Width
DashStyle
Opacity

Hello nandhumca,

Thanks for your post.

You could use a Stroke property as input to accomplish your goal. The Stroke class is used to characterize how a plot is visually displayed (plotted) on a chart.

See this help guide page for more information about the Stroke class: https://ninjatrader.com/support/help...roke_class.htm

More examples of using the Stroke class could be found in this help guide page: https://ninjatrader.com/support/help...8/?addplot.htm

Let us know if we may assist further.

Thanks I will define a parameter with type Stroke and explore.

Hi Brandon,

I tried with below code to get line properties via Stroke. It is not showing option to select any. Do you have any sample code to use Stoke as input for indicator to draw lines ?

[NinjaScriptProperty]
[Display(Name="LineProp", Order=7, GroupName="Line")]
public Stroke LineProp { get; set; }

Hello nandhumca,

Did you set a default value so the stroke is not null? In SetDefaults you would need:

LineProp = new Stroke();

Let us know if we may assist further.

Thanks Brandon. Now I am able to get the dashStyle, Brush and width from Stroke (LineProp). How to get the value of Opacity ? I am using Stroke value something like below

Draw.Line(this, "LineGT1"+CurrentBar, true, 1, Close[1], -5, Close[1], LineProp.Brush, LineProp.DashStyleHelper, (int)LineProp.Width);

Hello nandhumca,

For the property you made it would be:

LineProp.Opacity

Let us know if we may assist further.

Hi ,
I tried above method.
But the changes in the user input is not updated in the chart.

I am using the user input "Stroke" in Addplot.

Hello nobody31985,

For a Plot you would generally use a Brush input. I would suggest to try making a Brush input and then utilize that. If you still see a problem please open a new post for your individual question.
