Introduction of the Bouhmidi Bands
The bouhmidi bands ® were developed by Salah-Eddine Bouhmidi and are based on implied volatility. They calculate an expected daily bandwidth under the assumption of normally distributed returns.
The bandwidth is based on 1σ or 2σ. This means that an underlying closes with a probability of 68% or 95% within the expected Bouhmidi bandwidth at the end of the day. Historical data over the past 20 years shows a strong robustness of the indicator.
