I understand we can use Data Consolidators to pipe data to indicators. It seems that we can only pipe one custom data to one indicator.
I may have missed something in the documentation. Can we create two custom datafeed (sourced from quandl) and consolidate both of them into a single custom indicator?
I'm experimenting with creating a (VIX-VXV) contango indicator using daily close prices of VIX and VXV from quandl.
Thanks!

// the functional indicator takes as arguments two functions, // the first is a ComputeNextValue function // the second is an IsReady function ratio_VXV_VIX = new FunctionalIndicator("ratio",
point => RatioIndicator_ComputeNextValue(point, smaVXV, smaVIX),
ratioIndicator => RatioIndicator_IsReady(ratioIndicator, smaVXV, smaVIX)
);
Defined lower in Main.csprivate decimal RatioIndicator_ComputeNextValue(IndicatorDataPoint data, IndicatorBase vxv,
IndicatorBase vix)
{
return vxv / vix;
}
private bool RatioIndicator_IsReady(IndicatorBase functionalIndicator,
IndicatorBase vxv,
IndicatorBase vix)

Let me know if this works for you!Adrian Tang

Would someone be willing to provide an example of this in Python?
JohnCunningham
I'd also appreciate an example in python.
Wally Tung
Same here. I am looking forward with an example in Python. Thanks in advance!

Hi All,
As custom data Yahoo VIX and VXV is not available in this algorithm, we've updated this algorithm with the quandl data and simplify the algorithm with Indicator Extensions. This is the C# example
Jing Wu
This is the Python example
Nate Wine
Thank you Jing!
Huy Hoang
Thanks, Jing Wu ! Really appreciate the python example you put forward.
