is bollinger bands serve as a handy tool?

Hi friends hope you all are fine. According to my knowledge Bollinger Bands serve as a little handy tool that tells traders if the market shows a loud or quiet sound. If the market shows a quiet sound, the Bollinger Bands contract. But if the market shows a loud sound, the Bollinger Bands widen. If the market is seen out of the Bollinger Bands, it can be considered to be a trading signal - in case of trade entries as well as exits. Best wishes. Thanx to all of you
