The Bollinger Bands® indicator is an oscillator meaning that it operates between or within a set range of numbers or parameters. As previously mentioned, the standard parameters for Bollinger Bands® are a 20 day period with standard deviations 2 steps away from price above and below the SMA line.
Essentially Bollinger Bands® are a way to measure and visualize volatility. As volatility increases, the wider the bands become. Likewise, as volatility decreases, the gap between bands narrows.
What to Look for?
The bands must be thought of as a high and a low points, if the prices cross above the top band it means the asset is overbought and the opposite would indicate an oversold market.
