Bollinger Bands as a Volatility Tool, Not a Signal | Trading Systems Lab

This episode explores the use of Bollinger Bands as a sophisticated volatility measurement framework rather than a source of simple buy or sell signals. While novices often mistake a touch of the upper or lower bands as a direct cue to trade, professional systems utilize these tools to identify market conditions and price stability. The source emphasizes that volatility compression, or a squeeze, acts as a precursor to significant movements, while volatility expansion indicates the start of a trend. By analyzing the width and slope of the bands, automated strategies can distinguish between ranging and trending environments to apply the appropriate logic. Ultimately, the author argues that these indicators serve as an adaptive filter that determines when market conditions justify taking a risk.
