Bollinger Band

Bollinger Band
The Bollinger band consists of an upper, middle, and lower band created by John Bollinger.

The Bollinger Bands are used to measure price fluctuations above and below the Simple Moving Average (Simple MA). John Bollinger noted that periods with low volatility are followed by periods with high volatility. So when the Bollinger Bands get tighter and closer together, it can be concluded that significant price movements will occur soon.

Thus, the Bollinger Bands tight trading strategy helps to take advantage of price movements after a period of low volatility.
