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.

All trading involves risk.
The value of shares, ETFs and ETCs bought through a share dealing account, a stocks and shares ISA or a SIPP can fall as well as rise, which could mean getting back less than you originally put in. Past performance is no guarantee of future results.
