Trading Option Greeks: How Time, Volatility, and Other Pricing Factors Drive Profit

Most options traders focus on strategies such as covered calls, vertical spreads, butterflies and condors, and so on. But traders often don't know how to use the "greeks"—the five factors that influence an option's price—to trade more effectively.

The "greeks" (Delta, Gamma, Theta, Vega, Rho) are tools to measure minute changes in an option's price based on corresponding changes in:

• Interest rates
• Time to expiration
• Price changes in the underlying security
• Volatility
• Dividends

Using the greeks can lead to more accurate pricing information that will alert an option trader to mispriced derivatives that can be exploited for profit. In straightforward language and making use of charts and examples, Passarelli explains how to use the greeks to be a better options trader.
