The VolatilityFlex Levels indicator computes the degree of change (or sigma) by leveraging the selected Volatility Index (such as VIX or any user-specified volatility index). It utilizes this information to graphically represent distinct levels for a designated financial instrument. These levels include -sigma, -3/4sigma, -1/2sigma, -1/4sigma, 1/4sigma, 1/2sigma, 3/4sigma, and sigma.
