What Is the MI Bollinger Band Indicator
The MI Bollinger Band Indicator is an enhanced version of the traditional Bollinger Bands. It uses standard deviation and a moving average to create a dynamic price channel that expands and contracts based on market volatility.
The indicator helps traders:
Identify volatile and quiet market conditions

How the MI Bollinger Band Indicator Works
The indicator calculates the standard deviation of the closing price over a specified period and plots two bands around a moving average.
It consists of:
Upper Band: Moving average + standard deviation
Lower Band: Moving average – standard deviation
When market volatility increases, the bands widen. When volatility decreases, the bands contract.
