They can be used both as a volatility indicator and a momentum oscillator
Bollinger Bands can be applied on any underlying asset across any time frame
The indicator generates signals that not only provide precise entry levels, but also specify stop loss and take-profit zones
Disadvantages
Bollinger Bands work better in sideways markets than in trending markets
While it is possible to identify extreme price readings with Bollinger Bands, they are not ideal for this purpose
Even though Bollinger Bands can trigger their own signals, it is important to use these signals in concurrence with other aspects of technical analysis
