BollingerBands

Summary

Bollinger Bands are used to confirm signals. The bands indicate overbought and oversold levels relative to a moving average.

Remarks

Bollinger bands widen in volatile market periods, and contract during less volatile periods. Tightening of the bands is often used a signal that there will shortly be a sharp increase in market volatility.
