Dan Passarelli

Dan Passarelli worked as an options market maker on the floor of the Chicago Board Options Exchange (CBOE) and the Chicago Mercantile Exchange before transitioning to education. His book "Trading Option Greeks: How Time, Volatility, and Other Pricing Factors Drive Profit" (2008) is widely used by retail traders learning to work with option sensitivity measures. He founded Market Taker Mentoring to teach systematic options trading using market-maker techniques adapted for individual investors. Passarelli is known for making complex options concepts accessible without oversimplifying the underlying mechanics. His curriculum — covering delta hedging, volatility surface analysis, and the practical implications of pin risk and gamma exposure near expiration — has given thousands of retail options traders a professional-grade conceptual foundation that significantly improves their ability to manage risk and construct positions with defined and understood risk profiles.
