Bollinger Band Breakouts with Standard Deviation Levels

Summary

This document presents a Bollinger Band strategy built around a moving average and standard deviation bands. The accompanying description says to enter long above the two standard deviation upper band and short below the lower band, while using one standard deviation levels as stops. It discusses adjustable lookback and deviation settings, possible filters, and the risk that breakouts can fail or that restrictive levels can suppress trades.

The published configuration uses Bitcoin futures, daily bars, and a one hour base period over roughly a year, but no returns, drawdowns, or other test results are supplied. There is an important mismatch between the prose and the included source: its entry conditions cross the one standard deviation bands, and it closes positions on opposite signals rather than implementing the described one standard deviation stop. Treat the writeup as a strategy concept and verify the actual rules before interpreting or reproducing any backtest.

Key ideas

• The strategy uses a simple moving average and standard deviation to define Bollinger Band levels.
• The prose specifies entries beyond the two standard deviation bands and stop levels at one standard deviation.
• The source code instead enters on crosses of the one standard deviation bands and exits on opposite signals.
• The document gives backtest settings but no performance results.
• False breakouts, overly restrictive signals, and parameter choices are identified as risks.
