Bollinger Band Breakouts Confirmed by EMA Crossovers
Summary
This strategy combines Bollinger Bands, which reflect price dispersion, with an exponential moving average used to gauge trend direction. It enters long when the close crosses above the EMA and is above the upper band, and short when the close crosses below the EMA and is under the lower band. Percentage-based stop and target levels define exits, while position size is calculated from a chosen fraction of equity at risk.
The document describes the indicator logic and default settings, but supplies no performance results to validate the approach. It notes that parameter choices can affect signals, false breakouts and choppy or reversing markets can produce losses, and slippage and trading costs may erode returns. Suggested refinements include confirming trends with other indicators, adapting exits to volatility, reviewing position sizing, and combining timeframes. These are proposals rather than tested improvements, so the rules require careful evaluation for the intended market and trading conditions.
Key ideas
- Long entries require a close above both the EMA and upper Bollinger Band after crossing the EMA.
- Short entries require a close below both the EMA and lower band after crossing below the EMA.
- Stop and target prices use fixed percentages, while position size is tied to the selected risk amount.
- False breakouts, ranging markets, parameter sensitivity, slippage, and fees can weaken results.
- Additional trend filters and volatility-aware exits are proposed but not validated in the document.
