The upper and lower bands of the Bollinger Bands are extremely narrow, indicating that a major market movement could happen at any time. When the price breaks above the middle band of the Bollinger Bands and the subsequent pullback at the circle does not break the middle band, it is the best time to enter a long position. After entering, the upper and lower bands of the Bollinger Bands begin to widen, and the price moves between the upper and middle bands. However, it is not necessarily better for the upper and lower bands to open wider; the wider they open, the greater the demand for price correction, which also indicates increased risk for long positions.
