Put Call Ratio Bollinger Bands

1 528
WHAT IT DOES:
Plots the CBOE equity put/call ratio with Bollinger Bands to create an adaptive, self-calibrating sentiment gauge. Unlike fixed thresholds (e.g., "P/C > 0.90 = fear"), the Bollinger Bands adjust to the current regime, so the indicator works whether VIX is at 12 or 35.
HOW TO READ IT:
• Ratio touches UPPER Bollinger Band = ELEVATED FEAR / HEAVY PUT BUYING Contrarian bullish signal. Crowd is heavily hedged or bearish. Good entry zone for: bull put spreads, cash-secured puts, or selling put premium generally. Mean reversion favors sellers.
• Ratio touches LOWER Bollinger Band = COMPLACENCY / HEAVY CALL BUYING Contrarian bearish warning. Crowd is aggressively bullish. Tighten stops, add protective puts, reduce bullish exposure, or initiate bear call spreads.
• Ratio near MIDDLE band = NEUTRAL — no extreme sentiment signal Follow your primary regime strategy without sentiment override.
ADDITIONAL FEATURES:
• Equity-only vs. Total P/C ratio toggle (equity-only is more retail-focused)
• Divergence detection: when price makes new highs but P/C ratio rises (smart money hedging into strength = distribution warning)
• Smoothing options to reduce daily noise
WORKS WITH: VIX Term Structure + VIX Z-Score for full regime system
