out of bound issue

[kuroro13]

I have a problem with this simple code below. May someone help ?
Seems to be an out of bound issue....


#region Variables
// Wizard generated variables
private int length = 20; // Default setting for Length
// 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.Aqua), PlotStyle.Line, "Xaverageorig"));
Add(new Line(Color.FromKnownColor(KnownColor.Menu), 0, "Zero"));
CalculateOnBarClose = true;
Overlay = false;
PriceTypeSupported = false;

}

/// <summary>
/// Called on each bar update event (incoming tick)
/// </summary>
protected override void OnBarUpdate()
{

if (CurrentBar == 1) {Xaverageorig[0]=Input[0];}
else


{Xaverageorig[0]=Xaverageorig[1]+(1/length)*(Input[0]-Xaverageorig[1]);}

}

You cannot access [1] when CurrentBar == 0.

and how can i change that ?

At the top of OnBarUpdate()

if (CurrentBar < 1)
     return;

I did as you told me and add this script on top of my code BUT when I try to plot in a chart I only get constant values. Here's the result of my output window.

kuroro13,

Now you need to debug your script and try to figure out how it is evaluating your calculations. I suggest printing out values for each of the components and calculating by hand to see why it is doing what it is doing.
