Question Please give the definition of 'Lambda'.
Advice from Guru
Hello ForexGuy,

The ratio of the percentage change in an option contract's price to the percentage change in the option's underlying price. Lambda is one of the Greeks – a collection of risk measures or risk sensitivities that are frequently used in options and derivatives analysis. Each Greek measures the sensitivity of a value in relation to a small change in an underlying parameter. Lambda measures the change in option premiums for a percentage point change in its implied volatility. When the lambda value is high, the price of an option will be more sensitive to small changes in volatility. Conversely, when lambda is low, changes in volatility will have less impact on the option's value.
