I'm trying to build an oscillator (Aroon Oscillator) by subtracting 2 indicators in the Community Library - AroonUp.Series - AroonDown.Series.

This should be a simple DataSeries operation, but the code (below) gives me an error saying "error CS0019: Operator '-' cannot be applied to operands of type 'method group'"

Pl advise how to fix this error - am i missing a declaration? I thought AroonUp.Series and AroonDown.Series are DataSeries objects.
