What Bollinger Bands Show

Bollinger Bands consist of a middle moving average and two outer bands. The centre line reflects the short-term trend. The upper and lower bands show how far prices shift from that trend. When the bands widen, the market becomes more volatile. When they tighten, conditions turn calm. These changes offer early clues about possible breakouts.

Reading Signals From the Bands

The tool helps traders read price behaviour quickly. A move near the upper band often shows strong buying interest. A move near the lower band can show selling pressure. These simple signals help traders judge whether price is stretched or ready to reverse. They also guide basic entry and exit decisions within a volatility-based approach.

The Importance of the Band Squeeze

A squeeze occurs when the bands contract for a while. It signals low volatility and suggests a strong price move may follow. Traders watch closely for a breakout in either direction. This makes the squeeze one of the most watched patterns in any bollinger bands trading strategy.

Using Bollinger Bands to Understand Trends

The bands also help with trend analysis. If price stays close to the upper band in an uptrend, momentum often remains firm. If it stays near the lower band in a downtrend, weakness may continue. These patterns are easy to read and work well for traders who prefer simple tools.

Conclusion

Bollinger Bands offer practical insights into volatility and price strength. They help traders spot opportunities, prepare for breakouts, and understand market behaviour. Their clear structure and adaptability make them a reliable part of a straightforward and effective trading approach.
