Lesson 8: 4.7: Volatility Bands: Bollinger Bands & ATR
Implement Bollinger Bands and Average True Range (ATR) to measure volatility and place stop losses.
1. Bollinger Bands & ATR Mechanics
Bollinger Bands consist of a middle moving average (typically 20 SMA) and two outer bands set at +/- 2 standard deviations. Because standard deviation measures volatility, the bands expand during active periods and contract during low-volatility squeezes.
Average True Range (ATR) measures the average trading range over N periods, accounting for gaps. It is used to size stop losses dynamically based on the asset's current volatility footprint.
★ Volatility Rule: Bollinger Band Squeezes are often followed by massive, explosive breakout expansions.
