# Elegant Oscillator Elegant Oscillator is an indicator on [Vela](https://vela.luxalgo.com/chart), our next-generation charting platform, written in Pine Script®. Plots John Ehlers' Elegant Oscillator: a 2-bar price derivative normalized by its 50-bar root mean square, compressed by the inverse Fisher transform and finished with a 20-period SuperSmoother, bounded between -1 and +1. Dashed rails at 0.9 mark one-sided momentum, and eight alerts cover zero crosses, rail reaches and fades, and exhaustion events. - Indicator in the LuxAlgo Library, by LuxAlgo, published May 9, 2026. - Access: free. - Concepts: [Elegant Oscillator](https://www.luxalgo.com/library/concept/elegant-oscillator/) (primary) - Open on Vela: https://vela.luxalgo.com/chart?pineScriptCodeId=vs80eijfdfkc00375kypiyda - Page: https://www.luxalgo.com/library/indicator/elegant-oscillator/ **Elegant Oscillator** turns raw momentum into a smooth line that lives between -1 and +1, bringing the published [Elegant Oscillator](https://www.luxalgo.com/library/concept/elegant-oscillator/) recipe to the library in full. A short price derivative is divided by its own root mean square so every market lands on a comparable scale, the inverse Fisher transform squeezes the result toward the rails, and a final SuperSmoother pass removes what jitter remains. The line is colored by its side of zero, with an optional glow that flares near the bounds. ## How to Trade the Elegant Oscillator? - **Zero cross**: the smoothed momentum changing sides, alerted in both directions, with optional circle markers. - **Rail reach and fade**: a push beyond the 0.9 rail marks established one-sided momentum; the fade back through it marks that state ending. All four transitions carry alerts. - **Exhaustion**: price prints a fresh extreme of the lookback while the oscillator, having reached the matching rail earlier, fails to return to it, with diamonds and alerts on both sides. ## Elegant Oscillator Settings - **Source** (default close): series fed to the momentum derivative. - **Derivative Span** (default 2): bars spanned by the price derivative. - **RMS Window** (default 50): bars in the root-mean-square average that normalizes the derivative. - **SuperSmoother Period** (default 20): critical period of the final smoothing. Longer is cleaner but laggier. - **Rail Proximity Level** (default 0.9): absolute reading treated as being at a rail; anchors the rail and exhaustion events. - **Exhaustion Price Lookback** (default 50): window used to flag fresh price extremes. - Style: **Rail Glow** (on), **Zero Cross Markers** and **Exhaustion Markers** (off). The alerts fire either way. ## Frequently Asked Questions ### How does this relate to the Inverse Fisher Transform? The [Inverse Fisher Transform](https://www.luxalgo.com/library/indicator/inverse-fisher-transform/) applies the same compression to an oscillator you choose. Here it is one stage of a fixed recipe (derivative, RMS normalization, transform, SuperSmoother), so the input is always unit-scaled momentum and the output arrives pre-smoothed. ### Why does the line spend so long near +1 or -1? By design: the transform pushes normalized readings toward its asymptotes, so persistent momentum saturates at a rail instead of drifting off-scale. That is what makes the rail-fade events readable as momentum releasing. ### What does an exhaustion event mean? A fresh price extreme with the oscillator stuck short of its rail: effort without matching momentum. It warns that one-sided pressure is thinning. The zero cross remains the side change. ## Related indicators - [Internal Candle Strength](https://www.luxalgo.com/library/indicator/internal-candle-strength/) (Balance of Power): markdown at https://www.luxalgo.com/library/indicator/internal-candle-strength.md - [Pretty Good Oscillator](https://www.luxalgo.com/library/indicator/pretty-good-oscillator/) (Momentum & Oscillators): markdown at https://www.luxalgo.com/library/indicator/pretty-good-oscillator.md - [Gator Oscillator](https://www.luxalgo.com/library/indicator/gator-oscillator/) (Momentum & Oscillators): markdown at https://www.luxalgo.com/library/indicator/gator-oscillator.md - [Wave Trend Oscillator](https://www.luxalgo.com/library/indicator/wave-trend-oscillator/) (Momentum & Oscillators): markdown at https://www.luxalgo.com/library/indicator/wave-trend-oscillator.md - [Traders Dynamic Index](https://www.luxalgo.com/library/indicator/traders-dynamic-index/) (Momentum & Oscillators): markdown at https://www.luxalgo.com/library/indicator/traders-dynamic-index.md - [Center of Gravity](https://www.luxalgo.com/library/indicator/center-of-gravity/) (Momentum & Oscillators): markdown at https://www.luxalgo.com/library/indicator/center-of-gravity.md - [QQE Weighted Oscillator](https://www.luxalgo.com/library/indicator/qqe-weighted-oscillator/) (QQE): markdown at https://www.luxalgo.com/library/indicator/qqe-weighted-oscillator.md - [5/35 Oscillator](https://www.luxalgo.com/library/indicator/5-35-oscillator/) (Momentum & Oscillators): markdown at https://www.luxalgo.com/library/indicator/5-35-oscillator.md --- Source: https://www.luxalgo.com/library/indicator/elegant-oscillator/ (LuxAlgo Library).
