Indicator Doesn't Plot

[texasnomad]

My code compiles, but the indicator doesn't draw anything on the chart. I checked that "Skewness" is loaded under Initialize() and that I set the value. Once again I am neglecting something basic... just need someone to point me in the right direction please.


protected override void Initialize()
{
Add(new Plot(Color.FromKnownColor(KnownColor.Orange), PlotStyle.Line, "Skewness"));
CalculateOnBarClose = true;
Overlay = false;
PriceTypeSupported = false;
closeOpen = new DataSeries(this);
sDev = new DataSeries(this);
}


protected override void OnBarUpdate()
{
closeOpen.Set(Close[0] - Open[0]);
if ( CurrentBar >= barLookBack )
{
sDev.Set(StdDev(closeOpen, barLookBack)[0]) ;

double xBar = Convert.ToDouble(SMA(closeOpen , barLookBack));
double sumofCloseOpen = 0 ;

for(int i = barLookBack; i >= 0; i--)
{
sumofCloseOpen = Math.Pow(closeOpen[i] - xBar, 3) + sumofCloseOpen ;
}

Skewness.Set(1 / ( (barLookBack - 1) * Math.Pow(sDev[0], 3) ) * sumofCloseOpen);
}
}

First start by checking the LOG tab for some error.

If you don't have any, I would start by checking each variable value by adding Print() statements and opening the Output dialog.

double xBar = Convert.ToDouble(SMA(closeOpen , barLookBack));

Unable to cast object of type 'NinjaTrader.Indicator.SMA' to type System.IConvertible.


I changed xBar to a DataSeries and got it working.

Thanks again mrlogik.
