Setup: sell the 0.20–0.30 delta call and 0.20–0.30 delta put, 30–45 DTE, on a stock with elevated IV rank. Probability of profit at entry is typically 60–70%. The structure prints theta every day the stock stays between the short strikes and IV doesn't expand. Capital-efficient compared to short straddles because the profit zone is wider, but still undefined-risk on both sides.
Management: take profit at 50% of credit received. Defend losing sides by rolling out and away when one short strike is breached. Avoid holding through earnings or major events — the gap risk dwarfs the premium. Most premium-selling careers are built on running diversified short strangle portfolios across uncorrelated tickers, sized to survive multiple simultaneous adverse moves.
