These "Bollinger Bands" scans can help you find stocks which are exhibiting certain volatility characteristics and/or patterns. A major concept behind the bands is that stocks continually move between phases of high volatility to low volatility and back to high. Another usage is to identify when a stock is (relatively) high or low -- the lower band is considered low, while the upper band is considered high.

The Bolling Band Squeeze scans will identify stocks as they begin, remain in, or exit a low-volatility phase. Conversely, stocks with wide (widely spread) bands are in a high volatility phase.

A Bollinger Band Walk indicates a high level of price momentum. Price may walk up the upper band or down the lower band.
