Bull Put Spread Strategy Lab
What is a bull put spread?
A bullish vertical spread strategy which has limited risk and reward. It combines a long and short put which caps the upside, but also the downside.
The goal is for the stock to be above strike B, which allows both puts to expire worthless.
Execution Legs:
1
Buy a put at strike A.
2
Sell a put at strike B (higher strike).

Institutional Playbook & Ideal Timing
🎯 Ideal Timing & Volatility Environment:
High IV regime (IV Rank > 50%) where options premiums are overpriced. Ideal right before/after earnings for IV crush, during elevated market fear/VIX spikes, or in rangebound consolidation between Put and Call Walls.
🎯 Strike & DTE Target:
30 to 45 DTE. Sell the 30-delta strike at support/resistance, buy the 15-delta wing for protection.
🛡️ 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.
