Extra indicators
Fisher Transform
Turns the price's position in its recent range into sharp peaks and troughs that make turning points stand out.
用通俗的话解释
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.
计算方法
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₋₁如何使用
- Fisher crossing its trigger line marks a likely turn.
- Extreme readings (beyond ±1.5 to ±2) warn of exhaustion.
得出结论
- Sharp, sudden turns are typical: it is designed to be decisive.
示例
