# Phase-Based Profit Locking Implementation Summary
|
||
|
|
|
||
|
|
## Overview
|
||
|
|
Successfully implemented progressive phase-based profit locking system to protect profits while allowing trades breathing room. This addresses the critical vulnerability where positions could retreat from higher phases without locking in any profit.
|
||
|
|
|
||

|
||
|
|
|
||
|
|

## How It Works
|
||
|
|
|
||
|
|
### Phase Lock Calculation Flow
|
||
|
|
|
||
|
|
```
|
||
|
|
1. Determine Current Phase (based on current profit)
|
||
|
|
↓
|
||
|
|
2. Calculate Base Lock (minimum for phase)
|
||
|
|
↓
|
||
|
|
3. Calculate Progressive Lock (% of excess profit)
|
||
|
|
↓
|
||
|
|
4. Apply Breathing Room (50% pullback allowed)
|
||
|
|
↓
|
||
|
|
5. Apply Dynamic Adjustments:
|
||
|
|
- Strong Momentum → 30% looser
|
||
|
|
- Weak Momentum → 20% tighter
|
||
|
|
- High Volatility → 30% tighter
|
||
|
|
- Phase Retreat → 20% tighter
|
||
|
|
↓
|
||
|
|
6. Enforce Minimum Phase Lock (safety floor)
|
||
|
|
↓
|
||
|
|
7. Convert to Price Level & Apply
|
||
|
|
```
|
||
|
|
|
||
|
|
### Example Scenarios
|
||
|
|
|
||
|
|
#### Scenario 1: Normal Profit Growth
|
||
|
|
```
|
||
|
|
Entry → 50 pts (PROTECTION)
|
||
|
|
Base Lock: 10 pts
|
||
|
|
Progressive: (50-10) × 30% = 12 pts
|
||
|
|
Total: 22 pts
|
||
|
|
Breathing Room: (50-22) × 50% = 14 pts
|
||
|
|
Effective Lock: 22 - 14 = 8 pts
|
||
|
|
✓ Stop at entry +8 pts
|
||
|
|
|
||
|
|
→ Drops to 35 pts (INITIAL)
|
||
|
|
Highest Phase: PROTECTION (remembered)
|
||
|
|
Min Lock: 10 pts (maintained)
|
||
|
|
Retreat Detected: 10 × 1.2 = 12 pts
|
||
|
|
✓ Stop tightened to entry +12 pts
|
||
|
|
✓ Protected against further erosion
|
||
|
|
```
|
||
|
|
|
||
|
|
#### Scenario 2: Strong Momentum
|
||
|
|
```
|
||
|
|
Entry → 120 pts (MAXIMIZATION)
|
||
|
|
Momentum: 2.1 (strong)
|
||
|
|
Base Lock: 50 pts
|
||
|
|
Progressive: (120-50) × 50% = 35 pts
|
||
|
|
Momentum Adjustment: 35 × 0.7 = 24.5 pts (looser)
|
||
|
|
Total: 50 + 24.5 = 74.5 pts
|
||
|
|
Breathing Room: (120-74.5) × 50% = 22.75 pts
|
||
|
|
Effective Lock: 74.5 - 22.75 = 51.75 pts
|
||
|
|
✓ Loose enough to let trend run
|
||
|
|
|
||
|
|
→ Pullback to 90 pts
|
||
|
|
Current (90) > Lock (51.75)
|
||
|
|
✓ Trade continues with breathing room
|
||
|
|
```
|
||
|
|
|
||
|
|
#### Scenario 3: Weak Momentum
|
||
|
|
```
|
||
|
|
Entry → 80 pts (ACCUMULATION)
|
||
|
|
Momentum: 0.4 (weak)
|
||
|
|
Base Lock: 25 pts
|
||
|
|
Progressive: (80-25) × 40% = 22 pts
|
||
|
|
Momentum Adjustment: 22 × 1.2 = 26.4 pts (tighter)
|
||
|
|
Total: 25 + 26.4 = 51.4 pts
|
||
|
|
Effective Lock: 37.1 pts (after breathing room)
|
||
|
|
✓ Tighter protection in weak trend
|
||
|
|
```
|

## Configuration Guide
|
||
|
|
|
||
|
|
### Conservative Settings (Protect More)
|
||
|
|
```
|
||
|
|
InpPhaseLockBreathingRoom = 40 // Less breathing room
|
||
|
|
InpRetreatLockMultiplier = 1.3 // Tighter on retreat
|
||
|
|
InpPhase1MinLock = 15 // Higher minimums
|
||
|
|
InpPhase2MinLock = 30
|
||
|
|
InpPhase3MinLock = 60
|
||
|
|
```
|
||
|
|
|
||
|
|
### Aggressive Settings (Let Trades Run)
|
||
|
|
```
|
||
|
|
InpPhaseLockBreathingRoom = 60 // More breathing room
|
||
|
|
InpRetreatLockMultiplier = 1.1 // Gentler on retreat
|
||
|
|
InpPhase1MinLock = 8 // Lower minimums
|
||
|
|
InpPhase2MinLock = 20
|
||
|
|
InpPhase3MinLock = 40
|
||
|
|
```
|
||
|
|
|
||
|
|
### Disable Feature
|
||
|
|
```
|
||
|
|
InpUsePhaseProfitLocks = false // Turn off completely
|
||
|
|
```
|
||
|
|
|
||
|

## Key Benefits
|
||
|
|
|
||
|
|
### 1. **Progressive Protection**
|
||
|
|
- Automatically locks more profit as position grows
|
||
|
|
- Each phase has guaranteed minimum protection
|
||
|
|
- Can't fall below achieved phase level
|
||
|
|
|
||
|
|
### 2. **Breathing Room**
|
||
|
|
- Allows 50% retracement from peak (configurable)
|
||
|
|
- Prevents premature exits in trending markets
|
||
|
|
- Adapts to momentum and volatility
|
||
|
|
|
||
|
|
### 3. **Smart Retreat Handling**
|
||
|
|
- Remembers highest phase achieved
|
||
|
|
- Maintains minimum lock from peak phase
|
||
|
|
- Tightens protection by 20% on retreat
|
||
|
|
|
||
|
|
### 4. **Dynamic Adaptation**
|
||
|
|
- **Strong Momentum (>1.5):** 30% looser locks
|
||
|
|
- **Weak Momentum (<0.5):** 20% tighter locks
|
||
|
|
- **High Volatility (>1.5):** 30% tighter locks
|
||
|
|
- **Phase Retreat:** 20% tighter locks
|
||
|
|
|
||
|
|
### 5. **Architecture Integrity**
|
||
|
|
- Works within existing phase system
|
||
|
|
- No breaking changes to current logic
|
||
|
|
- All parameters user-configurable
|
||
|
|
- Transparent dashboard display

## Testing Recommendations
|
||
|
|
|
||
|
|
### 1. **Backtest Scenarios**
|
||
|
|
- Trending markets (verify breathing room works)
|
||
|
|
- Ranging markets (verify locks protect)
|
||
|
|
- High volatility periods (verify tightening works)
|
||
|
|
- Whipsaw conditions (verify retreat logic)
|
||
|
|
|
||
|
|
### 2. **Key Metrics to Monitor**
|
||
|
|
- **Profit Retention Rate:** % of peak profit captured
|
||
|
|
- **Average Lock Per Phase:** Verify appropriate levels
|
||
|
|
- **Premature Exit Rate:** Should decrease
|
||
|
|
- **Trend Capture Efficiency:** Should improve
|
||
|
|
|
||
|
|
### 3. **Parameter Optimization**
|
||
|
|
Test combinations of:
|
||
|
|
- Breathing room: 40%, 50%, 60%
|
||
|
|
- Retreat multiplier: 1.1, 1.2, 1.3
|
||
|
|
- Phase minimums: Conservative vs Aggressive
|
||
|
|
|
||
|
|
### 4. **Visual Verification**
|
||
|
|
- Check dashboard shows correct lock levels
|
||
|
|
- Verify stops are actually being moved
|
||
|
|
- Confirm log messages show phase transitions
|
||
|
|
- Monitor sound alerts for lock application

## Troubleshooting
|
||
|
|
|
||
|
|
### Issue: Locks not being applied
|
||
|
|
**Check:**
|
||
|
|
1. `InpUsePhaseProfitLocks = true`
|
||
|
|
2. `InpUsePhaseManagement = true`
|
||
|
|
3. Position actually in profit
|
||
|
|
4. Check logs for "Failed to apply phase lock" errors
|
||
|
|
|
||
|
|
### Issue: Locks too tight (premature exits)
|
||
|
|
**Solution:**
|
||
|
|
1. Increase `InpPhaseLockBreathingRoom` to 60%
|
||
|
|
2. Decrease `InpRetreatLockMultiplier` to 1.1
|
||
|
|
3. Lower phase minimum locks
|
||
|
|
|
||
|
|
### Issue: Locks too loose (profit erosion)
|
||
|
|
**Solution:**
|
||
|
|
1. Decrease `InpPhaseLockBreathingRoom` to 40%
|
||
|
|
2. Increase `InpRetreatLockMultiplier` to 1.3
|
||
|
|
3. Raise phase minimum locks
|
||
|
|
|
||
|
|
### Issue: Dashboard not showing locks
|
||
|
|
**Check:**
|
||
|
|
1. `InpShowDashboard = true`
|
||
|
|
2. Positions actually have profit
|
||
|
|
3. Dashboard object count (should be 35)
|
||
