Vega is the measurement of an option's price sensitivity to changes in the volatility of the underlying asset. Vega represents the amount that an option contract's price changes in reaction to a 1% change in the implied volatility of the underlying asset.

The Option Vega indicator plots the option's Vega risk value which is based on the asset's price series. The indicator requires the option data to be specified in the Input values (expiration month, expiration year, strike price, etc). Delta shows the expected risk of option price movement which is based on price changes in the underlying asset.

When applied to a chart, this indicator displays one plot in a separate subchart from the main data series.
