Fourier Phase Rotation [forexobroker]
Fourier Phase Rotation reconstructs the fundamental phase of a 4-bar sliding window using sine and cosine projections. The phase angle phi rotates through the unit circle as the cycle progresses; a zero-cross of phi marks a cycle low (buy timing) or high (sell timing). Distinct from Hilbert: 4-point projection, no IIR filter ringing.
🔶 ALGORITHM
1. Detrended source = close - sma(close, N).
2. 4-point DFT bin 1 cosine: re = c0 - c2; sine: im = c1 - c3 where c_k = detrended source at lag k.
3. phase phi = atan(im / re), in [-pi/2, +pi/2].
4. Cycle-low complete = phi crosses zero up; cycle-high complete = phi crosses zero down.
5. Bias from close vs detrend SMA gates direction.
🔶 SIGNAL LOGIC
- Buy: phase up-cross AND close > detrend SMA AND not already long AND cooldown elapsed AND barstate.isconfirmed.
- Sell: phase down-cross AND close < detrend SMA.
- Position-lock state machine.
🔶 INPUTS
- Detrend SMA Length (default 20)
- Pullback EMA Length (default 8)
- Cooldown Bars (default 4)
- Visual: dashboard, glow, SMA toggle, buy / sell colors
🔶 ALERTS
FPR Buy, FPR Sell, FPR Any Signal, FPR Phase Up, FPR Phase Down, FPR Bias Up, FPR Bias Down, FPR Near Pi/2, FPR Webhook JSON.
🔶 LIMITATIONS
- 4-point projection has a fixed period of 4 bars; assumes any cycle of interest is roughly that scale. Longer cycles fold into the bias trend.
- atan (vs atan2) gives phase in [-pi/2, +pi/2]; sufficient for zero-cross detection but does not preserve quadrant disambiguation.
- Detrend SMA length is the dominant smoothing knob; longer SMA = cleaner cycle, more lag.
- Best on instruments with rhythmic intraday patterns; pure trends give muted phase oscillations.
