Institutional Playbook & Ideal Timing
🎯 Ideal Timing & Volatility Environment:
Low IV regime (IV Rank < 25%) where options are cheap. Ideal 2–3 weeks before earnings announcements, expected breakout beyond Put/Call walls, or major macro volatility events.
🎯 Strike & DTE Target:
30 to 45 DTE. Sell ATM or 20-delta strikes outside the 1σ expected move cone.
🛡️ Exit & Risk Rules:
Take profit at 50% of max profit (for credit/neutral) or 100%–200% ROI (for debit). Cut losses at 100% of debit paid (or 2x credit collected). Close before expiration if delta expands beyond 70.
Greeks Sensitivity & Mechanics
⚡ +Vega (Long Vol)
Benefits from IV expansion. Hurt by post-earnings IV crush.
⏳ −Theta (Decay Cost)
Loses premium value every day; needs swift price displacement.
🚀 +Gamma (Convexity)
Profit accelerates as underlying moves further in your direction.
Directional Bias (Δ)
Delta-Neutral (Δ ≈ 0): Directionless; relies on vol or decay.
