Fisher Transform
Turns the price's position in its recent range into sharp peaks and troughs that make turning points stand out.
La idea en pocas palabras
Prices are not normally distributed, which hides turning points. The Fisher transform reshapes the price's position within its recent range so extremes become clear spikes.
Cómo se calcula
Scale the candle's midpoint into −1…+1 inside the high–low range of N candles, smooth it, and apply ½·ln((1 + x) ÷ (1 − x)). The trigger is the previous value.
x = 0.66 × ((mid − LL) ÷ (HH − LL) − 0.5) + 0.67 × x₋₁
Fisher = 0.5 × ln((1 + x) ÷ (1 − x)) + 0.5 × Fisher₋₁Cómo usarlo
- Fisher crossing its trigger line marks a likely turn.
- Extreme readings (beyond ±1.5 to ±2) warn of exhaustion.
Sacar conclusiones
- Sharp, sudden turns are typical: it is designed to be decisive.
Ejemplo
GOLD H4: Fisher reaches +2.4 and crosses below its trigger; the rally pauses for the next few candles.

- In strong trends it can stay extreme and give early reversal signals.
