Extra indicators
Fisher Transform
Turns the price's position in its recent range into sharp peaks and troughs that make turning points stand out.
الفكرة بكلمات بسيطة
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.
طريقة الحساب
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₋₁كيفية الاستخدام
- Fisher crossing its trigger line marks a likely turn.
- Extreme readings (beyond ±1.5 to ±2) warn of exhaustion.
استخلاص النتائج
- Sharp, sudden turns are typical: it is designed to be decisive.
مثال
GOLD H4: Fisher reaches +2.4 and crosses below its trigger; the rally pauses for the next few candles.
