Tom Sosnoff

Mechanical Options Selling, 45 DTE / 16-Delta Framework

Background

Tom Sosnoff is the founder of tastytrade (now IG-owned) and the creator of the thinkorswim platform (sold to TD Ameritrade for $750M). He is the most influential options trading educator alive, having made over 1,000 hours of free educational content advocating for mechanical, probability-based options selling. His philosophy: trade small, trade often, collect premium.

Core Methodology

Sosnoff's approach is based on selling options premium — specifically selling strangles and iron condors at 45 days to expiration (DTE) and the 16-delta strike (one standard deviation out-of-the-money). The mathematical foundation: options are statistically overpriced relative to realised volatility, so consistent premium sellers capture the variance risk premium over time.

Key Trading Rules

Tom Sosnoff — Distilled Rules
  • Sell premium at 45 DTE — optimal balance of time decay (theta) and gamma risk
  • Use 16-delta strikes for short strangles — one standard deviation out-of-the-money on each side
  • Manage winners at 50% of max profit — close when you've captured half the premium
  • Manage losers at 21 DTE — if still open, close regardless of P&L to avoid gamma acceleration
  • Trade small: no single position should risk more than 2-5% of portfolio
  • Trade often: 50+ positions across uncorrelated underlyings for portfolio-level diversification

Best Trading Courses Verdict
Positive. Sosnoff has given away more high-quality options education for free than anyone in history. The mechanical framework is well-researched and statistically grounded. The 45 DTE / 16-delta / manage-at-50% system is simple, repeatable, and backed by extensive backtesting. The caveat: selling premium in crash environments can produce catastrophic losses — tail risk management is essential.
