Trend Range King
- Experts
- Frank Paetsch
- Version: 2.9
- Updated: 8 November 2025
- Activations: 5
-
Dual engine, one mapper: Both the Trend (follow) and Range (mean reversion) modules are mapped around per-symbol/TF baselines (EMAs, TrendGap, RSI thresholds, Range flatness/deviation, ATR SL/TP/trails).
-
Volatility-driven ranges: The ATR-percentile p moves thresholds and exits relatively around their baselines, keeping trade logic aligned with current market regime.
-
Adaptive EMAs: On each AO recalculation, EMA periods are remapped and their alphas refreshed so incremental EMAs track the effective periods in real time.
-
Stable regime handling: Mapping + hysteresis provide smooth transitions between trend and range states with fewer parameter shocks.
-
Testable & portable: Baseline versioning ensures repeatable OOS tests and consistent performance across instruments without frequent re-optimization.
Trend Range EA: The Best of Two Worlds (Trend + Mean Reversion)
A refined evolution of the 5-star-rated Trend King EA (proven on higher TFs like H4), now fused with a powerful mean-reversion engine for sideways markets. A robust, bar-based approach that adapts to both regimes.
Highlights
-
Dual core: Trend engine (ATR-normalized EMA gap + hysteresis + RSI) & Range engine (ATR deviation + RSI center; optional Engulfing/Inside Bar).
-
Validation & broker friendly: open-prices-only, once-per-bar, lightweight, no grid/martingale, no DLL, ECN-safe.
-
Risk control: ATR SL/TP, ATR trailing/BE, fixed lot or % risk, auto magic, spread guard, session filter, spike shield.
-
Easy to optimize: clean, coarse-grained parameters that create plateaus instead of spiky optima.
How it trades
-
Trend: rides sustained moves (best on H4/H1).
-
Range: buys/sells pullbacks within the band (M15–H1).
-
Backtests: fixed spread, Open prices only.
Included
Presets & a short optimization guide. No hidden testing modes, no external dependencies.

I’m thrilled to hear it’s performing well for you in both the Trend and Range modules. Passing your optimized settings into the AO mapping is exactly how it’s meant to be used—once the baselines are snapped, it gets very close to “set & forget.” If you’d like, feel free to share your set files or symbols/TFs and I can suggest tweaks (AUTO/FIXED/SNAP Baseline modes, ATR gates, etc.). Wishing you continued smooth, green pips! 💚
