Using the Inverse Fisher Transform to Refine RSI Signals

Summary

This indicator applies Ehlers’ inverse Fisher transform to several RSI variants, including regular RSI, Cutler’s RSI, Haris’ RSI, Rapid RSI, RSX, and Slow RSI. The stated aim is to emphasize oscillator extremes, making overbought and oversold conditions more distinct and potentially helping identify trend direction more cleanly. Additional smoothing is offered as a way to reduce false signals.

Users can choose fixed thresholds or floating levels based on a selected period, with colors and alerts responding to those levels. Multi-timeframe use and alerts on open or closed bars are also described. The document provides no performance data or precise parameter recommendations, and advises experimentation for each instrument and timeframe. Its claims about faster or cleaner detection are not supported by comparative tests here, so the indicator’s value requires independent evaluation.

Key ideas

• The inverse Fisher transform is applied to multiple RSI variants to accentuate oscillator extremes.
• Thresholds may be fixed or calculated as floating levels over a chosen period.
• Smoothing and threshold-based colors or alerts can shape how signals are presented.
• The document offers no measured performance evidence, so settings should be evaluated for each market and timeframe.
