Definition of Greeks as the sensitivity of an option's price and risk (in the first row) to the underlying parameter (in the first column). First-order Greeks are in blue, second-order Greeks are in green, and third-order Greeks are in yellow. Vanna, charm and veta appear twice, since partial cross derivatives are equal by Schwarz's theorem ...
Theta: Theta measures the change in the option price for every one-day change in the option’s expiration. Options are a wasting asset, meaning their value declines over time, and theta measures ...

In the case of neutral strategies, they can be further classified into those that are bullish on volatility, measured by the lowercase Greek letter sigma (σ

The equation states that over any infinitesimal time interval the loss from theta and the gain from the gamma term must offset each other so that the result is a return at the riskless rate. From the viewpoint of the option issuer, e.g. an investment bank, the gamma term is the cost of hedging the option.
A brain signal frequency (beta, alpha, theta, delta) ranging from 4–8 Hz; One of the variables known as "Greeks" in finance, representing time decay of options or the change in the intrinsic value of an option divided by the number of days until the option expires [20]
The sensitivity of the option value to the amount of time to expiry is known as the option's theta. The option value will never be lower than its IV . As seen on the graph, the full call option value ( IV + TV ), at a given time t , is the red line.
