How to plot more than 1 plot in one indicator?

[user721]

Hi;

Would you please explain to me why this code won't plot 2 plots on a chart:

#region Variables
Double MA3Len = 34;
Double MA5Len = 8;
#endregion

protectedoverridevoid Initialize()
{
Add(new Plot(Color.FromKnownColor(KnownColor.Fuchsia), PlotStyle.Line, "MA3"));
Add(new Plot(Color.FromKnownColor(KnownColor.Fuchsia), PlotStyle.Line, "MA5"));
Overlay = false;
}
protectedoverridevoid OnBarUpdate()
{
Value.Set(CurrentBar == 0 ? Input[0] : Input[0] * (2.0 / (1 + MA3Len)) + (1 - (2.0 / (1 + MA3Len))) * Value[1]);
Value.Set(CurrentBar == 0 ? Input[0] : Input[0] * (2.0 / (1 + MA5Len)) + (1 - (2.0 / (1 + MA5Len))) * Value[1]);
}

Thank you

Hello,

Thanks for the forum post and welcome to the NinjaTrader support forum.

You would need to make the following change.

MA3.Set(CurrentBar == 0 ? Input[0] : Input[0] * (2.0 / (1 + MA3Len)) + (1 - (2.0 / (1 + MA3Len))) * Value[1]);

MA5.Set(CurrentBar == 0 ? Input[0] : Input[0] * (2.0 / (1 + MA5Len)) + (1 - (2.0 / (1 + MA5Len))) * Value[1]);

You need to name it the same as the name you gave the plot up in Initialize.

Let me know if I can be of further assistance.

Hi; thank you for your help;

When I change the code as you said (change Value to MA3 & MA5) I get error code CS0103. In the help for this error it says to be sure and declare the variables before you use them. So I tried that and that gives me error CS1061. What am I not getting? thanks

user721, please have a look into your properties section as well in the code as the public properties of the plots would need defining there as well, this could be easiest seen if you review some of the default NT indicators or create the raw indicator structure needed in our indicator wizard.

Thanks,

To use that code, you must define the properties of the plots correctly. If you do not want to define the plots in the properties, then you have to use the in-built Values DataSeries collection thus:

Values[0].Set(CurrentBar == 0 ? Input[0] : Input[0] * (2.0 / (1 + MA3Len)) + (1 - (2.0 / (1 + MA3Len))) * Value[1]);

Values[1].Set(CurrentBar == 0 ? Input[0] : Input[0] * (2.0 / (1 + MA5Len)) + (1 - (2.0 / (1 + MA5Len))) * Value[1]);
