Bollinger Bandwidth Squeeze: Mathematical Formula, Indicator Calculation & Sizing Rules
Bollinger Bandwidth Squeeze evaluates Volatility Compression & Breakout Detector. Its core mathematical equation is: Bandwidth = ((Upper Band - Lower Band) / Middle Band) x 100. Standard parameters use 20-period SMA, 2.0 Sigma. A confirmed signal occurs when Squeeze < 5%, Expansion > 15%. Integrating Bollinger Bandwidth Squeeze into automated risk clearance eliminates emotional entries and establishes quantitative stop-loss boundaries.
Developed by John Bollinger, Bollinger Bandwidth Squeeze provides objective quantitative measurement of Volatility Compression & Breakout Detector. Unlike subjective visual chart patterns, Bollinger Bandwidth Squeeze is grounded in statistical price dispersion, moving averages, and volatility geometry.

Mathematical Deconstruction of Bollinger Bandwidth Squeeze
The mathematical robustness of Bollinger Bandwidth Squeeze derives from its formula: Bandwidth = ((Upper Band - Lower Band) / Middle Band) x 100. By smoothing price oscillations across 20-period SMA, 2.0 Sigma, it isolates genuine structural market moves from random noise, giving systematic traders statistical confidence.
Avoiding Indicator Whipsaws in Low-Volatility Chop
In range-bound markets, Bollinger Bandwidth Squeeze can produce premature entry signals. Quantitative hedge funds filter signals by pairing Bollinger Bandwidth Squeeze with higher-timeframe market structure (BOS/CHOCH) and volume confirmation before committing capital.
