The B Bandwidth Ratio Indicator for MT4 is a specialized tool designed to measure market volatility using Bollinger Bands. By plotting a histogram that represents the distance between the upper and lower Bollinger Bands, this indicator helps traders quickly identify periods of low and high volatility, commonly known as squeeze patterns.

Since price movements often accelerate after periods of low volatility, the B Bandwidth Ratio Indicator is an effective tool for anticipating potential breakout scenarios, even though it does not provide direct buy or sell signals.
How the B Bandwidth Ratio Indicator Works
- Histogram/Oscillator Line – Plots the bandwidth between the upper and lower Bollinger Bands.
- High Bandwidth → Increased volatility, larger potential price movement
- Low Bandwidth (Squeeze) → Decreased volatility, potential upcoming breakout
A squeeze occurs when the Bollinger Bands contract into a narrow range. Following John Bollinger’s principles, periods after a squeeze often see aggressive price moves, making this indicator invaluable for preparation and strategy planning.
Trading Strategy and Usage
While the indicator does not generate trading signals, it can be used in several practical ways:
Volatility Analysis
- Monitor the oscillator for expanding or contracting bandwidth
- Anticipate periods of high volatility to adjust trade size or stop-loss levels
Squeeze Pattern Detection
- Narrow bandwidth → Low volatility → Price may breakout soon
- Prepare for potential breakout trades aligned with other technical indicators
Risk Management
- Use bandwidth readings to determine stop-loss adjustments
- Increase stop-loss range during high volatility phases
- Tighten stop-loss when volatility is low
Key Features
- Measures volatility using Bollinger Bands distance
