Why I get wrong index?

[_Roman]

I get this code:
private Series<double> OpenBuffer;

protected override void OnStateChange()
{
if (State == State.SetDefaults)
{
Description = @"Введите описание новой пользовательской Индикатор здесь.";
Name = "МойПользовательскийIndicator";
Calculate = Calculate.OnBarClose;
IsOverlay = false;
DisplayInDataBox = true;
DrawOnPricePanel = true;
DrawHorizontalGridLines = true;
DrawVerticalGridLines = true;
PaintPriceMarkers = true;
ScaleJustification = NinjaTrader.Gui.Chart.ScaleJustification.Right;
IsSuspendedWhileInactive = true;
AddPlot(new Stroke(Brushes.DarkGray, DashStyleHelper.Dash, 1), PlotStyle.Line, "Main Value");
}
else if (State == State.Configure)
{
OpenBuffer = new Series<double>(this);
}
}

protected override void OnBarUpdate()
{
//Добавьте логику пользовательского indicator здесь.
OpenBuffer[0] = Values[0][0] = CurrentBar;
}

protected override void OnRender(ChartControl chartControl, ChartScale chartScale)
{
if (ChartControl == null)
return;
base.OnRender(chartControl, chartScale);
try
{
for (int chartBarIndex = ChartBars.FromIndex; chartBarIndex <= ChartBars.ToIndex; chartBarIndex ++)
Print (Values[0].GetValueAt(chartBarIndex) + " " +OpenBuffer.GetValueAt(chartBarIndex)+" " +chartBarIndex);
}
catch (Exception exc)
{
Print("OnRender failure chart: " + exc.ToString());
}
}
}
The indicator must print Value from start visible bar to end visible bar and 3 values must be iqual. But the real result is not iqual values. See Attachment. Why indicator get wrong index?

Hi, thanks for posting. Set the BarsRequiredToPlot = 0; in State.SetDefault to start plotting immediately when the data starts and these numbers should match up.

Kind regards.

Hello Dear Friend!
Thank you for answer.

// Store all series values instead of only the last 256 values
MaximumBarsLookBack = MaximumBarsLookBack.Infinite;

This is parameter need for draw full indexes.

Thank you.
