Smoothed StdError Development

[pjwinner]

I'm trying to write an EMA of StdError. What I get is a line that seems to simply touch the close of each bar. I used the Indicator Wizard. My only input for the Wizard was a Period of 20. Could anyone spot what I've done wrong? Thanks for the help. Here's the code.


// This namespace holds all indicators and is required. Do not change it.
namespace NinjaTrader.Indicator
{
/// <summary>
/// EMA of Standard Error
/// </summary>
[Description("EMA of Standard Error")]
public class StdErrorSmoothed : Indicator
{
#region Variables
// Wizard generated variables
private int period = 20; // Default setting for Period
// 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, "Plot0"));
Overlay = false;
}

/// <summary>
/// Called on each bar update event (incoming tick)
/// </summary>
protected override void OnBarUpdate()
{
// Calculate the standard error average
double average = EMA(StdError(30), Period)[0];

Plot0.Set(Close[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 Plot0
{
get { return Values[0]; }
}

[Description("Period of EMA")]
[GridCategory("Parameters")]
public int Period
{
get { return period; }
set { period = Math.Max(1, value); }
}
#endregion
}
}

It is doing what you told it to do.

Plot0.Set(Close[0]);

If you want to plot the average, then tell it to plot the average.

Plot0.Set(average);

Thanks for your help. It's always embarrassing to have the obvious pointed out!

Do not be embarrassed. You will be surprised how long I sometimes spend troubleshooting, only to find what is, in hindsight only, an obvious error.

As they say, "hindsight is 20/20".
