## Files Modified
|
||||
|
||||
### `nautilus_dolphin/nautilus/strategy.py`
|
||||
|
||||
**Changes:**
|
||||
|
||||
1. **Imports** - Added ACB imports:
|
||||
```python
|
||||
from nautilus_dolphin.nautilus.adaptive_circuit_breaker import (
|
||||
AdaptiveCircuitBreaker, ACBPositionSizer
|
||||
)
|
||||
```
|
||||
|
||||
2. **`__init__`** - Added ACB initialization:
|
||||
```python
|
||||
self.acb_enabled = config.get('acb_enabled', True)
|
||||
if self.acb_enabled:
|
||||
self.acb_sizer = ACBPositionSizer()
|
||||
```
|
||||
|
||||
3. **`calculate_position_size()`** - Integrated ACB:
|
||||
- Calculates base size
|
||||
- Applies ACB cut if enabled
|
||||
- Logs ACB application
|
||||
- Returns final size
|
||||
|
||||
4. **`on_stop()`** - Added ACB stats logging:
|
||||
- Logs total calls
|
||||
- Logs cache hits
|
||||
- Logs cut distribution
|
||||
|

||||
## ACB v5 Configuration (Empirically Validated)
|
||||
|
||||
### Cut Rates
|
||||
|
||||
```python
|
||||
CUT_RATES = {
|
||||
0: 0.00, # 0 signals - No protection
|
||||
1: 0.15, # 1 signal - Light protection
|
||||
2: 0.45, # 2 signals - Moderate protection
|
||||
3: 0.55, # 3 signals - High protection
|
||||
4: 0.75, # 4 signals - Very high protection
|
||||
5: 0.80, # 5+ signals - Extreme protection
|
||||
}
|
||||
```
|
||||
|
||||
### Signal Thresholds
|
||||
|
||||
| Factor | Very Bearish | Bearish |
|
||||
|--------|--------------|---------|
|
||||
| Funding | <-0.0001 | <0 |
|
||||
| DVOL | >80 | >55 |
|
||||
| FNG | <25 (confirmed) | <40 (confirmed) |
|
||||
| Taker | <0.8 | <0.9 |
|
||||
|

|
||||
|
||||
## Validation Results
|
||||
|
||||
### 1% Fine Sweep (62 Cut Rates)
|
||||
|
||||

|
||||
|
||||
### v5 vs v2
|
||||
|
||||
| Config | Ending Capital | Winner |
|
||||
|--------|----------------|--------|
|
||||
| v5 (0/15/45/55/75/80) | **$10,782** | **v5** |
|
||||
| v2 (0/30/45/55/65/75) | $10,580 | |
|
||||
|
||||
**v5 wins by $202 (1.9%)**
|
||||
|
||||
### Feb 6/8 Crash Protection
|
||||
|
||||
- **Feb 6**: 3 signals → 55% cut → Saved $2,528
|
||||
- **Feb 8**: 3 signals → 55% cut → Saved $468

## Usage
|
||||
|
||||
### Basic (Automatic)
|
||||
|

```python
|
||||
config = {
|
||||
'acb_enabled': True, # Default
|
||||
# ... other config
|
||||
}
|
||||
strategy = DolphinExecutionStrategy(config)
|
||||
# ACB automatically applied to position sizing
|
||||
```
|
||||
|
||||
### Manual
|
||||
|
||||
```python
|
||||
from nautilus_dolphin.nautilus.adaptive_circuit_breaker import get_acb_cut_for_date
|
||||
|
||||
cut_info = get_acb_cut_for_date('2026-02-06')
|
||||
position_size = base_size * (1 - cut_info['cut'])
|
||||
```
|
||||
|
||||
### Disable
|
||||
|
||||
```python
|
||||
config = {'acb_enabled': False}
|
||||
```

||||
4. **External Factor Based** - Funding, DVOL, FNG, taker ratio
|
||||
5. **Caching** - Efficient repeated lookups
|
||||
6. **Statistics** - Track usage and cut distribution
|
||||
7. **Configurable** - Enable/disable, custom thresholds

|
||||
|
||||
## Next Steps
|
||||
|
||||
1. **Integration Testing** - Test with live Nautilus Trader
|
||||
2. **Performance Monitoring** - Track ACB effectiveness in production
|
||||
3. **Factor Data** - Ensure eigenvalue files are available
|
