## 🧠 RegimeDetector
|
|
|
|
### Fonctionnalités
|
|
|
|
#### Détection de 4 Régimes
|
|
|
|
| Régime | Description | Stratégies Adaptées |
|
|
|--------|-------------|---------------------|
|
|
| **0: Trending Up** | Tendance haussière | Intraday, Swing |
|
|
| **1: Trending Down** | Tendance baissière | Intraday, Swing |
|
|
| **2: Ranging** | Sideways/consolidation | Scalping |
|
|
| **3: High Volatility** | Volatilité élevée | Swing (prudent) |
|
|
|
|
#### Technologie
|
|
|
|
✅ **Hidden Markov Models (HMM)**
|
|
- Modèle probabiliste
|
|
- Détection automatique
|
|
- Transitions fluides
|
|
|
|
✅ **Features Calculées** (6 features)
|
|
```python
|
|
- returns # Rendements
|
|
- volatility # Volatilité rolling
|
|
- trend # Pente SMA
|
|
- range # High-Low / Close
|
|
- volume_change # Changement volume
|
|
- momentum # Momentum 10 périodes
|
|
```
|
|
|
|
### Utilisation
|
|
|
|
```python
|
|
from src.ml.regime_detector import RegimeDetector
|
|
|
|
# Créer détecteur
|
|
detector = RegimeDetector(n_regimes=4)
|
|
|
|
# Entraîner sur données historiques
|
|
detector.fit(historical_data)
|
|
|
|
# Prédire régime actuel
|
|
current_regime = detector.predict_current_regime(market_data)
|
|
regime_name = detector.get_regime_name(current_regime)
|
|
|
|
print(f"Current regime: {regime_name}")
|
|
# Output: "Current regime: Trending Up"
|
|
|
|
# Obtenir probabilités
|
|
probabilities = detector.get_regime_probabilities(market_data)
|
|
|
|
# Statistiques
|
|
stats = detector.get_regime_statistics(market_data)
|
|
print(stats['regime_percentages'])
|
|
# Output: {'Trending Up': 0.35, 'Ranging': 0.40, ...}
|
|
```
|
|
|
|
### Adaptation Automatique
|
|
|
|
```python
|
|
# Adapter paramètres selon régime
|
|
base_params = {
|
|
'min_confidence': 0.6,
|
|
'risk_per_trade': 0.02
|
|
}
|
|
|
|
adapted_params = detector.adapt_strategy_parameters(
|
|
current_regime=current_regime,
|
|
base_params=base_params
|
|
)
|
|
|
|
# Exemple pour Trending Up:
|
|
# - min_confidence: 0.6 → 0.54 (plus agressif)
|
|
# - risk_per_trade: 0.02 → 0.024 (plus de risque)
|
|
```
|
|
|
|
### Filtrage Stratégies
|
|
|
|
```python
|
|
# Vérifier si stratégie devrait trader
|
|
should_trade = detector.should_trade_in_regime(
|
|
regime=current_regime,
|
|
strategy_type='scalping'
|
|
)
|
|
|
|
# Matrice de compatibilité:
|
|
# Scalping: OK en Ranging, éviter High Volatility
|
|
# Intraday: OK en Trending, éviter Ranging
|
|
# Swing: OK en Trending et High Volatility
|
|
```
|
|
