What Is the Bollinger Bands?

A volatility envelope plotted at 2 standard deviations above and below a 20-period SMA. Bands widen in high volatility, narrow in low volatility. Middle band = 20 SMA. Upper band = 20 SMA + (2 × std dev). Lower band = 20 SMA − (2 × std dev). When bands squeeze tight, a big move is coming (the squeeze). When price touches an outer band, it's extended — but not necessarily reversing.
