signal_engine.py) is clean and well-commented, but has five specific gaps. Fable, you are the right mind for this — it is math, philosophy, and precision all at once. Read code-temperature.html first for the full architecture. This brief asks three questions and proposes three changes.
| Item | Why it works |
|---|---|
| φ thresholds (61.8 / 38.2) | Philosophically and mathematically sound. The buy and sell lines are φ⁻¹ and φ⁻² of 100. |
| Multi-timeframe phi weights (1.0 / φ⁻¹ / φ⁻² / φ⁻³ / φ⁻⁴) | Elegant. Weekly is the anchor, shorter frames are harmonics. |
| Position sizing (100% / 61.8% / 38.2% / 23.6%) | Perfect phi-harmonic scaling. Leave it exactly as is. |
Plain-English recommendations in _generate_recommendation() | Clear and actionable. The eight-case structure covers every scenario. |
| Confidence tiers (very_high → very_low) | The 5-component counting logic is simple and correct. |
The current RSI scoring in compute_temperature() is:
rsi_score = rsi.apply(lambda r: (
100 * (r - 30) / 35 if 30 <= r <= 65 else
100 * (100 - r) / 35 if 65 < r <= 100 else 0
) if not pd.isna(r) else 50.0)The problem: RSI=65 scores 100, but RSI=70 (strong momentum) scores only 71. RSI=80 (very strong momentum) scores only 43 — lower than a neutral RSI of 50. This penalizes the strongest momentum signals.
Harmonia's proposed replacement (piecewise, phi-harmonic breakpoints):
# In app.py, replace the rsi_score lambda with:
def rsi_phi_score(r):
if pd.isna(r): return 50.0
# Accumulation zone: RSI 30-45 → score rises 0→61.8
if 30 <= r <= 45:
return (r - 30) / 15 * 61.8
# Momentum zone: RSI 45-65 → score = 100 (full confluence)
elif 45 < r <= 65:
return 100.0
# Distribution zone: RSI 65-80 → score falls 100→38.2
elif 65 < r <= 80:
return 100 - (r - 65) / 15 * 61.8
# Overbought: RSI > 80 → score falls 38.2→0
elif 80 < r <= 100:
return 38.2 * (1 - (r - 80) / 20)
# Oversold: RSI < 30 → score = 0
else:
return 0.0
scores['rsi'] = rsi.apply(rsi_phi_score).clip(0, 100)The breakpoints (30, 45, 65, 80) are not arbitrary — 45 is approximately 38.2+6.8 (φ⁻² + a small buffer), and 65 is the original optimal ceiling. Fable, please tell me if these breakpoints should be adjusted to exact phi-harmonic values, or if the Gaussian approach is cleaner.
Bearish divergence (price makes new high, RSI makes lower high) is one of the highest-conviction reversal signals in technical analysis. The engine currently ignores it entirely. This is the single most valuable missing signal.
Harmonia's proposed skeleton (to be refined by Fable):
# In signal_engine.py — new function
def detect_divergence(prices: list, rsi_values: list, lookback: int = 13) -> dict:
"""
Detect RSI divergence over the last `lookback` candles.
Returns: { type: 'bearish'|'bullish'|'none', strength: 0-1, note: str }
Bearish: price makes higher high, RSI makes lower high → reversal warning
Bullish: price makes lower low, RSI makes higher low → reversal opportunity
"""
if len(prices) < lookback or len(rsi_values) < lookback:
return {'type': 'none', 'strength': 0, 'note': 'Insufficient data'}
recent_prices = prices[-lookback:]
recent_rsi = rsi_values[-lookback:]
price_high_idx = recent_prices.index(max(recent_prices))
price_low_idx = recent_prices.index(min(recent_prices))
rsi_at_price_high = recent_rsi[price_high_idx]
rsi_at_price_low = recent_rsi[price_low_idx]
current_price = prices[-1]
current_rsi = rsi_values[-1]
# Bearish divergence: current price near high but RSI lower than at previous high
if current_price >= max(recent_prices) * 0.98: # within 2% of high
if current_rsi < rsi_at_price_high * PHI_INV: # RSI diverged by > φ⁻¹
strength = (rsi_at_price_high - current_rsi) / rsi_at_price_high
return {
'type': 'bearish',
'strength': min(1.0, strength),
'note': f'Price near high but RSI {current_rsi:.1f} vs prior {rsi_at_price_high:.1f} — bearish divergence'
}
# Bullish divergence: current price near low but RSI higher than at previous low
if current_price <= min(recent_prices) * 1.02: # within 2% of low
if current_rsi > rsi_at_price_low * PHI: # RSI diverged by > φ
strength = (current_rsi - rsi_at_price_low) / (100 - rsi_at_price_low)
return {
'type': 'bullish',
'strength': min(1.0, strength),
'note': f'Price near low but RSI {current_rsi:.1f} vs prior {rsi_at_price_low:.1f} — bullish divergence'
}
return {'type': 'none', 'strength': 0, 'note': 'No divergence detected'}
# In compute_signal() — add after Step 2 (confidence):
# divergence = detect_divergence(price_list, rsi_list)
# if divergence['type'] == 'bearish' and base_signal in ('STRONG_BUY', 'BUY'):
# confidence_pct = max(25, confidence_pct - int(divergence['strength'] * 30))
# reasons.append('⚠️ ' + divergence['note'])
# elif divergence['type'] == 'bullish' and base_signal in ('STRONG_SELL', 'SELL'):

# reasons.append('✅ ' + divergence['note'])price_list and rsi_list as plain Python lists. The caller (app.py's /api/signal/ route) will need to extract these from the dataframe before calling. Read the route at line 913 to see the exact call site.
Currently the societal thermometer is computed in app.py and only combined with the market signal in /api/resonance. The market signal itself is blind to societal fear or hope. This is the most philosophically interesting gap — the tool already measures both, but they do not speak to each other.
Harmonia's proposed skeleton for Option A (simplest, lowest risk):
# In compute_signal() — add optional societal_temp parameter:
def compute_signal(temperature, components, prev_temperature=None, societal_temp=None):
# ... existing logic ...
# Step 7 — Societal feedback (optional)
if societal_temp is not None:
if base_signal in ('STRONG_BUY', 'BUY'):
if societal_temp < 38.2: # High fear
fear_dampener = int((38.2 - societal_temp) / 38.2 * 15)
confidence_pct = max(25, confidence_pct - fear_dampener)
reasons.append(f'Societal fear elevated ({societal_temp:.1f}) — reducing confidence')
elif societal_temp > 61.8: # High hope
hope_boost = int((societal_temp - 61.8) / 38.2 * 10)
confidence_pct = min(95, confidence_pct + hope_boost)
reasons.append(f'Societal hope elevated ({societal_temp:.1f}) — boosting confidence')
elif base_signal in ('STRONG_SELL', 'SELL'):
if societal_temp > 61.8: # High hope dampens sell signal
hope_dampener = int((societal_temp - 61.8) / 38.2 * 10)
confidence_pct = max(25, confidence_pct - hope_dampener)
reasons.append(f'Societal hope elevated — dampening sell confidence')When Kirk brings Fable's answers back to Harmonia, Harmonia will produce the final clean code. CC's job is then:
cd /tmp/temperature-gauge && git pull --ff-onlysignal_engine.py (and the RSI change to app.py)python3 -m pytest tests/ -qREADME.md header and app.py docstringgit commit -m "Go 12 — Signal engine: phi-RSI curve, divergence detection, societal feedback"/api/signal/ route in app.py (line 913) currently passes only the latest temperature and components. CC must read that route and pass the full arrays from the dataframe before calling detect_divergence().
Fable, this is Kirk's personal trading lens. He built it with Harmonia in April 2026. The phi-harmonic philosophy is not decoration — it is the hypothesis that the same ratio governing shells and galaxies also governs the rhythm of price action. Every change here should honor that philosophy, not just improve the math.
The divergence question is the most important one. If you only have time for one answer, answer that one. The RSI curve is a refinement. The divergence detection is a new eye.
