Introduction to Bollinger Bands Strategy
Bollinger Bands® are a powerful technical analysis tool created by John Bollinger in the 1980s. This volatility indicator consists of three lines:
– A simple moving average (middle band)
– An upper band (typically 2 standard deviations above the middle)
– A lower band (typically 2 standard deviations below)
The strategy we’ll explore adapts these classic settings for enhanced cryptocurrency trading performance, potentially generating returns exceeding 900% in portfolio backtests.

Trading Rules and Execution
Entry Signals
- Long positions trigger when price closes above the upper primary band (2.5σ) while volatility expands (bandwidth > 0.01)
- Short positions activate when price closes below the lower primary band with confirmed volatility
Exit Strategies
- Take profit at the opposite secondary band (3.75σ)
- Stop-loss placed at the middle band (25-period SMA)
- Time-based exits after 5-7 days if targets aren’t hit

Q: How frequently should I adjust the strategy?
A: Conduct monthly performance reviews, but only modify parameters after significant market structure changes (typically quarterly).
Q: Does this work in bear markets?
A: Yes, the strategy’s shorting mechanism proved effective during 2022’s downturn, generating 284% returns while spot markets declined.
