## 📊 Test Scenario Details

### Test 1: Stop-Loss Widens in Volatile Regime ⏳
**Purpose**: Verify stop-loss adjusts from 1.5x → 3.0x → 4.0x ATR
**Scenario**:
1. Setup Ranging regime (1.5x ATR = 30 points on ES.FUT @4000)
2. Verify stop-loss @ $3970 (30 points below entry)
3. Change to Volatile regime (3.0x ATR = 60 points)
4. Verify stop-loss @ $3940 (60 points below entry)
5. Change to Crisis regime (4.0x ATR = 80 points)
6. Verify stop-loss @ $3920 (80 points below entry)

**Current Issue**: `order_with_stop.stop_loss.is_some()` assertion fails
**Root Cause**: Investigating - likely insufficient bars or ATR too small

### Test 2: Sell Order Stop-Loss Above Entry ⏳
**Purpose**: Verify SELL orders have stop-loss above entry price
**Scenario**:
1. Setup Normal regime (2.0x ATR = 100 points on NQ.FUT @20000)
2. Create SELL order @ $20,000
3. Verify stop-loss @ $20,100 (100 points ABOVE entry)

**Current Issue**: `order_with_stop.stop_loss.is_some()` assertion fails

### Test 3: Stop-Loss Prevents Immediate Trigger ✅
**Purpose**: Verify <2% stop-loss rejected
**Scenario**:
1. Setup Ranging regime with very low ATR (0.005 on 6E.FUT @1.10)
2. Calculate stop distance: 1.5x * 0.005 = 0.0075 = 0.68% of entry
3. Verify stop-loss NOT applied (< 2% threshold)

**Status**: ✅ PASS

### Test 4: ATR Calculation (14-Period) ✅
**Purpose**: Validate ATR calculation algorithm
**Scenario**:
1. Create 15 bars with consistent 20-point True Range
2. Calculate ATR with 14-period
3. Verify ATR ≈ 20.0

**Status**: ✅ PASS

### Test 5: Stop-Loss Persisted to Database ✅
**Purpose**: Verify metadata includes regime, ATR, multiplier
**Scenario**:
1. Apply stop-loss to ZN.FUT order
2. Verify metadata contains: regime, atr, stop_multiplier, stop_distance

**Status**: ✅ PASS

### Test 6: Real-World Volatility Spike ⏳
**Purpose**: Validate March 2023 banking crisis scenario
**Scenario**:
1. Normal period: ATR 15 points, 2.0x multiplier = 30 points stop
2. Crisis period: ATR 50 points, 4.0x multiplier = 200 points stop
3. Verify crisis stop > 3x normal stop

**Current Issue**: Option unwrap panic (investigating)

### Test 7: Multi-Symbol Different Regimes ⏳
**Purpose**: Validate concurrent regime handling
**Scenario**:
1. ES.FUT: Ranging (1.5x), ATR 20, expected 30 points
2. NQ.FUT: Volatile (3.0x), ATR 50, expected 150 points
3. ZN.FUT: Crisis (4.0x), ATR 3, expected 12 points

**Current Issue**: Option unwrap panic (investigating)

### Test 8: Performance Benchmark ✅
**Purpose**: Verify <5ms per order target
**Scenario**:
1. Apply stop-loss to 100 orders sequentially
2. Measure average time per order
3. Verify < 5000μs (5ms)

**Status**: ✅ PASS

### Test 9: Regime Multipliers Comprehensive ✅
**Purpose**: Validate all regime multipliers
**Test Data**:
- Ranging/Sideways: 1.5x
- Trending/Normal: 2.0x
- Volatile: 3.0x
- Crisis/Breakdown: 4.0x
- Unknown: 2.0x (default)

**Status**: ✅ PASS

## 🐛 Debugging Status

### Issue 1: Stop-Loss Not Applied
**Symptoms**: `order_with_stop.stop_loss.is_some()` returns false
**Potential Causes**:
1. Insufficient bars in database (need 15+ bars)
2. ATR calculation returns <2% of entry price
3. Regime query returning empty result
4. Bar data not inserted correctly (fixed-point conversion)

**Next Steps**:
1. Add debug logging to `apply_dynamic_stop_loss` function
2. Verify bar insertion logic (fixed-point to float conversion)
3. Check regime state exists before applying stop
4. Validate ATR calculation with test data

### Issue 2: Option Unwrap Panics
**Symptoms**: `called Option::unwrap() on a None value`
**Affected Tests**: test_multi_symbol_different_regimes, test_real_world_volatility_spike
**Potential Causes**:
1. `order_with_stop.stop_loss` is None
2. Metadata fields missing

**Next Steps**:
1. Add proper error handling instead of unwrap()
2. Use `expect()` with descriptive messages
3. Add assertions before unwrap calls
