Many brothers only know a bit about the Bollinger Bands, understanding the roles of support and resistance, but haven't learned the true secrets of the Bollinger Bands indicator. I specifically created a practical video to break it down in detail and reveal the usage techniques of this indicator.

1. When the upper and lower bands of the Bollinger Bands narrow and then open, if the price moves along the upper band, the larger the opening and the more the middle band rises, the stronger the price attack.

2. A strong breakthrough of the middle band indicates an entry point, and a breakthrough of the upper band allows for continued holding.

3. When the upper and lower bands narrow and then open, if the price moves along the lower band and the middle band turns downward, one should exit in time.

4. If the price breaks below the lower band and then returns above it with a medium-sized bullish candle, this is a rebound opportunity; one should exit upon encountering the middle band.

5. If the price breaks above the upper band and then retraces, the middle band can be treated as a support level.

6. If the price fluctuates around the middle band, it indicates a sideways market, allowing for buying low and selling high between the upper and lower bands.
