Using Bollinger Bands to Read Crypto Volatility and Trade Signals

Summary

The article explains how Bollinger Bands can help traders assess crypto volatility and possible market direction. The bands are described as a moving average with upper and lower boundaries typically set two standard deviations away. Narrowing bands indicate a quiet period that may precede a larger move, while wider bands reflect higher current volatility. A daily chart is recommended for judging broader conditions.

For trend interpretation, the article gives a bullish example: after a period of tight bands, price breaks above the upper band while the EMA slopes upward. It also describes a short-term band-based system that buys below the lower band and sells above the upper band, suggesting a 30-minute chart. The article reports different historical outcomes for THETA and BTC under this approach, but provides no detailed testing methodology. It cautions that Bollinger Bands lag, may miss trend beginnings, and can vary by exchange and coin settings; the examples should not be treated as evidence of reliable future performance.

Key ideas

• Bollinger Band width is used as a rough gauge of market volatility.
• A squeeze may precede a large move, but the indicator does not establish its direction by itself.
• An upper-band break combined with a rising EMA is presented as a possible bullish signal.
• The described scalping rule buys below the lower band and sells above the upper band.
• The article warns that the indicator lags and its settings and results can vary across markets.
