options greek values

Options greek values are measurements that traders use to determine how the price of an option changes as certain things change, such as the price of the stock, the amount of time until it expires, how much volatility there is, etc. Greek values are like a math equation that traders use to figure out how the option will react in different situations and help them decide if they should buy or sell. For example, if you bought an option and the price of the stock suddenly went up, the "Delta" greek value would tell you how much the option’s price also went up. This helps traders decide if they should keep the option or sell it.
