# EEO: Ehlers Elegant Oscillator
A bounded zero-crossing oscillator that applies the Inverse Fisher Transform to RMS-normalized 2-bar momentum, then smooths the result with a 2-pole Super Smoother filter. Output is approximately bounded to [-1, +1].
> *Where DSO shouts through a megaphone, EEO whispers through a compressor — the Inverse Fisher Transform tames extremes into a clean bounded signal.*

- EEO (Elegant Oscillator) applies the Inverse Fisher Transform (tanh) to RMS-normalized 2-bar momentum, then smooths the result with a 2-pole Super Smoother filter, producing a bounded zero-crossing oscillator.
- **Similar:** [DSO](../dso/Dso.md), [RSIH](../rsih/Rsih.md) | **Complementary:** ADX for trend confirmation | **Trading note:** Output bounded ≈ [-1, +1]; ±0.5 levels indicate strong momentum. Unlike DSO (unbounded), EEO compresses extremes via tanh.
- No external validation libraries implement EEO. Validated through self-consistency and behavioral testing.
EEO is Ehlers' 2022 refinement of his earlier DSO (2018). Where DSO applies the Fisher Transform (arctanh) to expand a normalized signal, EEO applies the **Inverse Fisher Transform** (tanh) to compress it. The IFT naturally bounds the output to [-1, +1] without the ±0.99 clamping that DSO requires. A Super Smoother post-filter then removes residual noise. The fixed 50-bar RMS normalization window provides a stable volatility baseline independent of the BandEdge parameter.
## Historical Context
Ehlers' 2022 "Elegant Oscillator" is a refinement of his earlier DSO (2018). Where DSO applies the Fisher Transform (arctanh) to expand a normalized signal, EEO applies the **Inverse Fisher Transform** (tanh) to compress it. The IFT naturally bounds the output to [-1, +1] without needing the ±0.99 clamping that DSO requires. A Super Smoother post-filter then removes residual noise.
John F. Ehlers published the Elegant Oscillator in the February 2022 issue of *Technical Analysis of Stocks & Commodities* magazine under the title "An Elegant Oscillator: Inverse Fisher Transform Redux." The article presents EEO as a deliberate counterpart to his 2018 Deviation-Scaled Oscillator (DSO). While DSO uses the Fisher Transform (arctanh) to stretch readings near zero into large excursions, EEO uses the Inverse Fisher Transform (tanh) to compress them — producing a naturally bounded output without the artificial clamping that DSO requires.
