Building a Regime-Adaptive Expert Advisor with Strategy-Specific Risk Settings
Summary
The document describes an MQL5 Expert Advisor that changes its trading approach according to a detected market regime. It uses trend-following logic for rising or falling trends, an RSI-based mean-reversion example in ranging conditions, and a Bollinger Band breakout example in volatile conditions. The EA processes data on new bars, waits for enough history, passes closes to a regime detector, and then selects the corresponding entry logic.
Risk settings also vary by regime through separate lot sizes, stop losses, and take profits; the volatile regime uses a smaller example position size. The article discusses tuning detector parameters for instruments and timeframes and managing regime transitions to reduce abrupt changes or whipsaws. It presents an implementation blueprint and describes backtesting as part of evaluation, but the supplied text does not include concrete performance figures or establish that the example rules are profitable. Results would depend on the detector, parameter choices, execution assumptions, and market tested.
Key ideas
- The EA maps trending, ranging, and volatile regimes to different entry strategies.
- Trend examples follow the detected direction, while range entries use RSI extremes and volatile entries use Bollinger Band breaks.
- Lot size, stop loss, and take profit are configured separately for each regime.
- New-bar processing and a minimum history requirement structure the detector workflow.
- Regime thresholds and transition handling require instrument- and timeframe-specific evaluation.
