Options Bootcamp 2: The Greeks Basic Training:
Risk variables (aka "the Greeks") are Delta, gamma, theta, and vega.
Delta: The measure of the sensitivity of the options' price given a change in the underlying instrument. It's also used to view the likelihood of whether an option will expire in-the-money.
Gamma: The rate of change of an options' delta given the change in the underlying instrument.
Theta: The rate of change of an options' value given a change in the number of days until an options' expiration.
Vega: The rate of change in an options' value given the change in implied volatility.
How professional traders use the Greeks and ways that novice traders can use them, too. It's a symbiotic relationship.
