Bollinger Band Breakouts Confirmed by Fast and Slow Moving Averages
Summary
This long-only trend strategy combines a volatility channel with moving-average filters. It enters when a bar closes above the upper Bollinger Band, the close is above the slow simple moving average, and the fast simple moving average is above the slow one. The described defaults use a 21-period band with a two-standard-deviation width, plus 6-period and 45-period averages. The band’s center average can be selected from several common types.
An open position exits if the close falls below the lower band or the fast average drops below the slow average. The document explains how these conditions aim to screen for upward momentum while adapting the channel width to recent volatility. It also outlines possible refinements, including volume or trend-strength filters, higher-timeframe confirmation, volatility-based sizing, and trailing stops.
No performance results are reported. The published test setup covers roughly one year of daily crypto futures data, but the document provides no return, drawdown, or benchmark figures. It flags lagging signals, whipsaws in range-bound markets, sensitivity to parameter choices, transaction costs, and the strategy’s inability to trade short. Its claims about signal quality therefore remain unverified by stated results.
Key ideas
- Long entries require an upper-band close, price above the slow average, and the fast average above the slow average.
- Positions exit on a close below the lower band or when the fast average falls below the slow average.
- The volatility channel expands and contracts with recent price variation, while its center average type is configurable.
- The strategy trades long only, and its lagging indicators may produce late entries or repeated signals in sideways markets.
- The document provides a daily crypto futures test period but no performance statistics to establish effectiveness.
