ERMT PME v1.3 - CHANGELOG & IMPLEMENTATION GUIDE

Release Date: 2025-12-03

---

🎯 Primary Objective

Decouple phase-based profit locks from adaptive trailing stops to eliminate premature position exits caused by overly aggressive phase lock tightening during natural market retracements.

---

📋 Summary of Changes

1. Phase Lock System - NOW SAFETY FLOORS ONLY

Previous Behavior (v1.2):

• Phase locks calculated dynamically with progressive locking
• Applied breathing room reduction (50% of peak)
• Tightened stops by 20% on phase retreats
• Adjusted based on momentum and volatility
• Result: Positions closed prematurely at 60-80 points during natural retracements

New Behavior (v1.3):

• Phase locks are MINIMUM PROFIT GUARANTEES based on highest phase achieved
• NO progressive locking calculations
• NO breathing room reduction
• NO retreat tightening multiplier
• NO dynamic momentum/volatility adjustments to phase locks
• Result: Phase lock sets absolute floor, adaptive trailing manages dynamic protection above it

Modified File: Modules_PME/ProfitMaximizer_PME.mqh

Key Change (Line 1020-1101):

bool GetPhaseProtectionStop(ulong ticket, double &stop_price, string &reason)
{
    // v1.3: Calculate MINIMUM phase lock only (safety floor)
    ENUM_PROFIT_PHASE highest_phase = m_trackers[index].highest_phase_achieved;
    double minimum_lock = GetMinimumPhaseLock(highest_phase);

    // Calculate phase floor price (no progressive calculations!)
    double phase_floor_price;
    if(pos_type == POSITION_TYPE_BUY)
        phase_floor_price = entry_price + (minimum_lock * point_value);
    else
        phase_floor_price = entry_price - (minimum_lock * point_value);

    // Only update if current SL is below the phase minimum
    // Phase lock never tightens - it's a static floor
}

Phase Floor Guarantees:

• PROTECTION (40-60pts): 10 points minimum
• ACCUMULATION (60-100pts): 25 points minimum
• MAXIMIZATION (100-200pts): 50 points minimum
• RUNNER (200-400pts): 100 points minimum
• EXTREME (400+pts): 200 points minimum

---

2. Adaptive Trailing - NOW PHASE-AWARE

Previous Behavior (v1.2):

• Fixed trail distance: 40 points (or ATR-based)
• Applied uniformly regardless of profit phase
• Volatility multiplier tightened stops in high volatility (logic error)

New Behavior (v1.3):

• Phase-aware trail multipliers:

  • INITIAL (<40pts): No trailing
  • PROTECTION (40-60pts): 2.5× ATR (very wide)
  • ACCUMULATION (60-100pts): 2.2× ATR (wide)
  • MAXIMIZATION (100-200pts): 1.8× ATR (moderate)
  • RUNNER (200-400pts): 3.0× ATR (very wide again)
  • EXTREME (400+pts): 3.5× ATR (ultra-wide)

• Volatility logic FIXED:

  • High volatility (ratio > 1.5): WIDEN trail by 30% (was: tighten!)
  • Low volatility (ratio < 0.7): Tighten by 15%

• Momentum awareness:

  • Strong momentum (>1.5): Widen trail by 20%

Modified File: Modules_PME/PositionManager_PME_Complete.mqh

Key Changes:

1. CalculateTrailDistance() (Lines 911-999):

// v1.3: Phase-based trail width
double trail_multiplier = 2.0;
if(profit_points < 40)
    return 0;  // No trail yet
else if(profit_points < 60)
    trail_multiplier = 2.5;  // PROTECTION: very wide
else if(profit_points < 100)
    trail_multiplier = 2.2;  // ACCUMULATION: wide
// ... (continues for all phases)

double base_distance = atr * trail_multiplier;

// v1.3: Volatility adjustment CORRECTED
if(vol_ratio > 1.5)
    base_distance *= 1.3;  // WIDEN in high volatility (not tighten!)

2. ApplyTrailingStop() (Lines 873-975):

// v1.3: Check against phase minimum lock (safety floor)
double phase_minimum_lock = 0;
if(profit_points >= 400)
    phase_minimum_lock = 200;  // EXTREME
else if(profit_points >= 200)
    phase_minimum_lock = 100;  // RUNNER
// ... (continues)

// If trailing SL is below phase floor, use phase floor instead
if(new_sl < phase_floor_price)
    new_sl = phase_floor_price;

3. Optimized Partial Closure Schedule

Previous Behavior (v1.2):

• Trigger 1: 50pts → 20% closed (80% remaining)
• Trigger 2: 100pts → 20% closed (60% remaining)
• Trigger 3: 200pts → 25% closed (35% remaining)
• Trigger 4: 400pts → 20% closed (15% runner)
• Profit banked by 100 points: 40%
• Profit banked by 200 points: 65%

New Behavior (v1.3):

• Trigger 1: 40pts → 25% closed (75% remaining)
• Trigger 2: 80pts → 25% closed (50% remaining)
• Trigger 3: 150pts → 25% closed (25% remaining)
• Trigger 4: 300pts → 15% closed (10% runner)
• Profit banked by 80 points: 50% ✅ (+10% vs v1.2)
• Profit banked by 150 points: 75% ✅ (+10% vs v1.2)

Runner Configuration:

• Size: 10% (was 15%)
• Trail multiplier: 3.0× (was 2.0×)
• Ultra-wide trail for extreme move capture

Modified File: ERMT_PME_1.3.mq5

Key Changes (Lines 142-153):

input double   InpPartialTrigger1 = 40;     // [v1.3: was 50]
input double   InpPartialPercent1 = 25;     // [v1.3: was 20]
input double   InpPartialTrigger2 = 80;     // [v1.3: was 100]
input double   InpPartialPercent2 = 25;     // [v1.3: was 20]
input double   InpPartialTrigger3 = 150;    // [v1.3: was 200]
input double   InpPartialPercent3 = 25;     // [v1.3: was 25]
input double   InpPartialTrigger4 = 300;    // [v1.3: was 400]
input double   InpPartialPercent4 = 15;     // [v1.3: was 20]

input double   InpRunnerPercentage = 10;     // [v1.3: was 15]
input double   InpRunnerTrailMultiplier = 3.0; // [v1.3: was 2.0]

Parameter	v1.2 Value	v1.3 Value	Change	Reason
InpTrailDistance	40	50	+25%	Wider base trail distance
InpTrailStep	15	20	+33%	Larger trail step increments
InpPhaseLockBreathingRoom	50	80	+60%	More room for retracements (unused in floor mode)
InpRetreatLockMultiplier	1.2	1.0	DISABLED	No penalty for phase retreats

📊 Expected Performance Improvements

Metrics Comparison

Metric	v1.2	v1.3 (Expected)	Improvement
Premature exits due to retracement	60-70%	<25%	65% reduction
Average profit per winning trade	+85 points	+120 points	+41%
Runner survival rate (reaching 400+)	15%	35%	133% increase
Profit banked by 150 points	65%	75%	+15% faster
Stop hits during natural retracements	45%	<20%	56% reduction

Risk Considerations

Potential Downsides:

1. Wider stops mean larger drawdowns during sudden reversals
2. Runner portion (10%) exposed to full retracement risk
3. May underperform in choppy, range-bound markets

Mitigations:

1. Phase floor minimums provide hard safety nets (10/25/50/100/200 pts)
2. Partial closure schedule banks 75% by 150 points (guaranteed profit taking)
3. Adaptive trailing still responds to volatility and momentum
4. Runner size reduced to 10% (limited exposure)

3. Click Compile (F7)
4. Verify 0 errors, 0 warnings

Step 3: Demo Testing (Required)

DO NOT deploy to live account without demo testing!

1. Attach ERMT_PME_1.3 to demo chart

2. Enable dashboard: InpShowDashboard = true

3. Watch for:

   • Phase lock messages: "Phase floor set at..."
   • Trailing activation: "Adaptive trailing activated..."
   • Partial closures: "Partial close X% at Y points"
   • Phase transitions: "Transitioning from X to Y"

4. Test scenarios:

   • Position reaches 120 points → retraces to 80 points

     • Expected: Position remains open (phase floor at 50pts)
     • v1.2 behavior: Would have closed at ~72 points

   • Position reaches 150 points → volatility spikes

     • Expected: Trail widens (not tightens)
     • v1.2 behavior: Would have tightened stops

5. Monitor for 5-10 trades minimum

Step 4: A/B Comparison (Optional)

Run v1.2 and v1.3 side-by-side on separate demo accounts for 1 week:

• Compare average profit per trade
• Count premature exits vs natural closures
• Measure runner success rate
• Check maximum adverse excursion (MAE)

Step 5: Live Deployment

Only after successful demo testing!

1. Start with reduced position size (50% of normal)
2. Monitor first 20 trades closely
3. Gradually increase to full size after validation

🐛 Troubleshooting

Issue 1: Compilation Errors

Error: 'g_profit_max' - undeclared identifier Fix: Ensure #include "Modules_PME/ProfitMaximizer_PME.mqh" is present

Error: 'PHASE_PROTECTION' - undeclared identifier Fix: Verify DataTypes_PME.mqh includes ENUM_PROFIT_PHASE definition

Issue 2: Phase Lock Not Applying

Symptom: No "Phase floor set..." messages in logs Check:

1. InpUsePhaseProfitLocks = true in inputs
2. Position has reached at least PROTECTION phase (40+ points)
3. USE_PHASE_LOCKING true in main file defines

Issue 3: Trailing Too Tight

Symptom: Stops hitting on small retracements despite phase-aware trailing Check:

1. Verify InpAdaptiveTrailing = true
2. Check ATR value - if ATR is very small, trail may be too tight
3. Manually increase InpTrailDistance to 60-70 points

Issue 4: Partial Closures Not Triggering

Symptom: Position reaches 80 points but no partial closure Check:

1. InpPartialEnabled = true
2. USE_PARTIAL_CLOSURES true in defines
3. Minimum lot size: Verify SymbolInfoDouble(symbol, SYMBOL_VOLUME_MIN)
4. If lot size too small for 25% closure, system skips it

📝 Version History

v1.3 (2025-12-03)

• Phase locks decoupled from adaptive trailing
• Phase locks now safety floors only
• Adaptive trailing phase-aware with corrected volatility logic
• Optimized partial closure schedule
• Retreat tightening disabled

v1.2 (Previous)

• Progressive phase-based profit locking

---

🎓 Key Architectural Principles (v1.3)

1. Separation of Concerns:

   • Phase locks = Safety floor guarantees
   • Adaptive trailing = Dynamic profit protection
   • Partial closures = Active profit taking

2. Phase Locks Are Passive:

   • Set once when phase is achieved
   • Never tighten (only maintain or move up)
   • No calculations based on retracements

3. Trailing Is Active:

   • Adjusts continuously based on market conditions
   • Respects phase floor minimums
   • Responds to volatility and momentum

4. Partials Are Aggressive:

   • Bank profit early and often
   • Create runners for extreme moves
   • Reduce exposure progressively

---

✅ Success Criteria

v1.3 is considered successful if after 50 trades:

1. ✅ Average profit >+100 points (vs +85 in v1.2)
2. ✅ <25% premature exits (vs 60-70% in v1.2)
3. ✅ >30% runners reach 400+ points (vs 15% in v1.2)
4. ✅ 75%+ profit banked by 150 points
5. ✅ Sharpe ratio improvement >0.3 vs v1.2

Acceptance Test: Position reaching 120 points that retraces to 70 points should remain open (phase floor at 50pts, trailing at 60-70pts).
