Aggiornato Robust Weighting Oscillator
Introduction
A simple oscillator using a modified lowess architecture, good in term of smoothness and reactivity.
Lowess Regression
Lowess or local regression is a non-parametric (can be used with data not fitting a normal distribution) smoothing method. This method fit a curve to the data using least squares.
In order to have a lowess regression one must use tricube kernel for the weightings w, the weightings are determined using a k-nearest-neighbor model.
lowess is then calculated like so :
Σ(wG(y-a-bx)^2)
Our indicator use G, a ,b and remove the square as well as replacing x by y
Conclusion
The oscillator is simple and nothing revolutionary but its still interesting to have new indicators.
Lowess would be a great method to be made on pinescript, i have an estimate but its not that good. Some codes use a simple line equation in order to estimate a lowess smoother, i can describe it as ax + b where a is a smooth oscillator, b some kind of filter defined by lp + bp with lp a smooth low pass filter and bp a bandpass filter, x is a variable dependent of the smoothing span.

Note di rilascio
Added G in a separate calculation mode, thanks to @ aaahopper for pointing it out. Changed color for downside movements.Script open-source
