Bollinger Band Breakouts Filtered by an EMA Trend Condition
Summary
This strategy combines Bollinger Bands, an EMA, and ATR. It calculates the bands from a moving average of closing prices and their standard deviation, then uses the EMA as a trend filter. A close above both the EMA and upper band triggers a long entry; a close crossing below the lower band or EMA triggers a short entry. ATR is calculated and plotted as a volatility reference, but the stated entry and exit rules do not use it for risk sizing or stops. The published example concerns BTC/USDT futures over a limited historical period and gives no performance statistics.
The method treats a move beyond the upper band in the direction of the EMA filter as a trend opportunity, with downside crossings prompting short entries. The document cautions that sideways markets and reversals can generate false signals, results are sensitive to indicator settings, and costs and slippage are not accounted for. It also identifies missing stop loss and position controls. Suggested improvements include testing parameter combinations, adding trend confirmation, using ATR for dynamic risk controls, and accounting for execution costs; none is validated by reported results.
Key ideas
- A long entry requires the close to be above both the EMA and upper Bollinger Band.
- A close crossing below either the lower band or EMA triggers a short entry.
- ATR is displayed as a volatility measure but is not part of the stated trading rules.
- The document reports no performance statistics and warns of false signals in sideways or reversing markets.
- Trading costs, slippage, stop losses, and position sizing are not addressed in the strategy rules.
