Hi,
Could somebody point out how to create chain of indicators based on another indicator with more than one level of hierarchy?
1. I want to create indicator that shows deviation between correlated stocks
2. For this I create 4 movings averages, Slow and Fast MA for the stock #1 and Slow and Fast MA for the stock #2
DoubleExponentialMovingAverage iFma1 = DEMA(iSymbol1, iPeriodFast, Resolution.Hour);
DoubleExponentialMovingAverage iSma1 = DEMA(iSymbol1, iPeriodSlow, Resolution.Hour);
DoubleExponentialMovingAverage iFma2 = DEMA(iSymbol2, iPeriodFast, Resolution.Hour);
DoubleExponentialMovingAverage iSma2 = DEMA(iSymbol2, iPeriodSlow, Resolution.Hour);
3. Then I create Composite Indicator for each stock by subtracting FMA from SMA, now I have de-trended oscillators for each stock
CompositeIndicator<IndicatorDataPoint> iOsc1 = iSma1.Minus(iFma1);
CompositeIndicator<IndicatorDataPoint> iOsc2 = iSma2.Minus(iFma2);
4. Now I want deviation to be calculated based on the difference between these oscillators
var deviation = new StandardDeviation(15);
iDev = deviation.Of(iOsc2.Minus(iOsc1));
This is where I get an error Cannot implicitly convert from StandardDeviation to CompositeIndicator<IndicatorDataPoint>
Any thoughts?

The return type of extension method Of is the same type of the object.
In this particular case, since deviation is an instance of StandardDeviation, so iDev should be.
CompositeIndicator<IndicatorDataPoint> iDev; // Wrong StandardDeviation iDev; // RightArtemiusgreat
