Five-Minute Dow Engulfing Strategy with Bollinger Trend Filters

Summary

This strategy trades five-minute Dow index bars when a bullish or bearish engulfing candle forms with a body exceeding a multiple of average true range. Two Bollinger-style bands, calculated from moving averages and standard deviations, provide trend filters. The rules enter long or short positions at market, use a fixed stop and a reward target set as a multiple of that stop, and move a trailing stop in steps after price advances. The author identifies the ATR and band periods as optimization variables, while other settings are described as moderate rather than thoroughly optimized.

Time filters aim to avoid periods the author associates with high spreads, near-close conditions, and major market openings, with daylight-saving adjustments and a UTC+8 clock reference. The document gives no numerical test results or evidence of robustness; it mentions that default parameters were not fully optimized. Results may depend on the platform’s time zone, data, spread assumptions, and execution. The posted code is an implementation reference, not proof that the setup is profitable.

Key ideas

• Entries require an engulfing candle whose body exceeds an ATR-based threshold.
• Two Bollinger-style measures classify bullish and bearish trend conditions.
• The rules pair fixed stop and target levels with a stepwise trailing stop.
• Time-of-day filters avoid selected spread and market-opening periods, with daylight-saving adjustments.
• The author says key periods are optimization variables but provides no test results in this document.
