It's all about the Plot

[mgbloomfield]

I'm trying to get a plot to appear on the 2nd panel. This is the simplest indicator. It simply plots a horizontal with a value of zero on each OnBarUpdate(). After several minutes, the plot does not appear.

(Eventually, this plot will have a math formula so it's not an oscillator line per se).

namespace NinjaTrader.Indicator
{
/// <summary>
/// Enter the description of your new custom indicator here
/// </summary>
[Description("Enter the description of your new custom indicator here")]
public class MyCustomIndicator : Indicator
{
#region Variables
// Wizard generated variables
// User defined variables (add any user defined variables below)
#endregion

/// <summary>
/// This method is used to configure the indicator and is called once before any bar data is loaded.
/// </summary>
protected override void Initialize()
{
Add(new Plot(Color.FromKnownColor(KnownColor.Orange), PlotStyle.Line, "PlotFoobar"));
CalculateOnBarClose = true;
Overlay = false;
PriceTypeSupported = false;
}

/// <summary>
/// Called on each bar update event (incoming tick)
/// </summary>
protected override void OnBarUpdate()
{
// Use this method for calculating your indicator values. Assign a value to each
// plot below by replacing 'Close[0]' with your own formula.
PlotFoobar.Set(0);
}

#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 PlotFoobar
{
get { return Values[0]; }
}

#endregion
}
}

Can you clarify-

- A value of zero is plotted for a few minutes and the the indicator plot vanishes?

Any error messages in the Log tab?

[mgbloomfield]

A value of zero is NEVER plotted. It never appears.

I've tried different values: 10, 20, 30, etc.

It just never appears in the first place.

Here's some background: Earlier today, I was using OpenTick data feed and the plot lines were working. Then when the market closed, I started using the simulated data feed and the plot lines stopped appearing.

I was using the simulated data feed to fire the OnBarUpdate() event. I've verified that OnBarUpdate() is firing via custom log messages.

Interesting...

I can confirm that my indicators visibly plots a line when using OpenTick. It does NOT plot a line when using the simulated data feed.

But why? It shouldn't make a difference?

When you run in the sim feed are there any historical bars? If not, you might have to wait 20 bars before you start to see a line.
