Implied Volatility

Indicator Type: Standalone

Frequency: Daily Chart Only

Chart Type: Interactive Charts Only

The Implied Volatility study, when added to the underlying asset, shows the at-the-money average implied volatility (IV) of the nearest monthly options contract that is 30-days out or more.

Implied Volatility (IV) is the estimated volatility of the underlying stock over the period of the option. IV can help traders determine if options are fairly valued, undervalued, or overvalued. It can therefore help traders make decisions about option pricing, and whether it is a good time to buy or sell options. Implied volatility is determined mathematically by using current option prices in a formula that also includes Standard Volatility (which is based on historical data). The resulting number helps traders determine whether the premium of an option is "fair" or not. It is also a measure of investors' predictions about future volatility of the underlying stock. Implied volatility is calculated using the Binomial model.

Implied Volatility (IV) is a forward-looking prediction of the likelihood of price change of the underlying asset.

  • Higher IV signifying that the market expects significant price movement.
  • Lower IV signifying the market expects the underlying asset price to remain within the current trading range.

Implied Volatility is also reflected within IV Rank study which compares the current level of IV to its historical range of values, and the IV Percentile study which is the percentage of days with IV closing below the current IV value over the prior 1-year.

By default we show the current day's Implied Volatility. You may also plot a rolling average Implied Volatility which can include the highest value over the period as well as the lowest value of the same period, plotted as a band around the average implied volatility. This is available for 5-Day, 1-Month, 3-Month, 6-Month, 1-Year and YTD.
