Options Greeks Workbook: Calculating and Using Delta, Theta, and Vega in Practice

Reading about the Greeks and being able to use them to make real trade management decisions are different skills. This workbook course builds Greek literacy through structured calculation exercises, sensitivity analysis templates, and worked management scenarios that show how Greek values translate into actionable decisions. By the end of this course you will be able to estimate an option position's P&L for a specified price move using delta and gamma, calculate the daily theta decay for a position and project it over the remaining days to expiration, interpret a position's vega exposure and estimate the impact of a one-point implied volatility change, build a position sensitivity table across a range of price and volatility scenarios, and use aggregate Greeks to compare two different trade structures before selecting one. What you will learn: - Delta and gamma P&L estimation worksheet: estimating position value change for a 1-point, 5-point, and 10-point move - Gamma risk exercise: calculating how delta changes after a large price move and what that implies for position risk - Daily theta calculation worksheet: computing dollar theta per day and projecting decay across a 30-day and 60-day option - Theta acceleration exercise: comparing daily theta at 30, 14, 7, and 1 day to expiration for an at-the-money option - Vega sensitivity calculation: estimating P&L impact of a 5-point implied volatility increase on long and short vega positions - Position sensitivity table template: a matrix of position value across five price levels and three implied volatility levels - Greek comparison worksheet: comparing the Greeks of two alternative trade structures to select the better match for a market view - Multi-leg position aggregate Greeks: calculating combined delta, theta, and vega for a two-leg and four-leg structure Each section presents a worked numerical example followed by a blank worksheet. Case studies illustrate common Greek-related surprises — a position that gains delta faster than expected near expiration due to gamma, a long option position that loses value despite a favourable price move because implied volatility dropped. Reflection prompts ask you to complete each calculation before reviewing the worked version. This course is designed for options traders who understand basic Greek definitions and want to develop the ability to use them in real trade analysis. Suitable for learners who are new to Greek calculations but have some experience with options. This course is informational and educational and does not constitute financial or investment advice.
