## 📊 MetricsCalculator
|
||||
|
||||
### Métriques Calculées (30+ métriques)
|
||||
|
||||
#### 1. Return Metrics (7 métriques)

|
||||
- avg_monthly_return # Return mensuel moyen
|
||||
- total_days # Nombre de jours
|
||||
- total_years # Nombre d'années
|
||||
```
|
||||
|
||||
#### 2. Risk Metrics (5 métriques)
|
||||
```python
|
||||
- sharpe_ratio # Sharpe Ratio
|
||||
- sortino_ratio # Sortino Ratio
|
||||
- calmar_ratio # Calmar Ratio
|
||||

|
||||
```
|
||||
|
||||

|
||||
```
|
||||
|
||||
### Utilisation
|
||||
|
||||
```python
|
||||
from src.backtesting.metrics_calculator import MetricsCalculator
|
||||
|
||||
calculator = MetricsCalculator(risk_free_rate=0.02)
|
||||
|
||||
# Calculer toutes les métriques
|
||||
metrics = calculator.calculate_all(
|
||||
equity_curve=equity_series,
|
||||
trades=trades_list,
|
||||
initial_capital=10000.0
|
||||
)
|
||||
|
||||
# Vérifier validité
|
||||
is_valid = calculator.is_strategy_valid(metrics)
|
||||
|
||||
# Générer rapport
|
||||
report = calculator.generate_report(metrics)
|
||||
print(report)
|
||||
```
|
||||
|
||||
### Critères de Validation
|
||||
|
||||
```python
|
||||
Critères minimaux pour stratégie valide:
|
||||
- Sharpe Ratio >= 1.5
|
||||
- Max Drawdown <= 10%
|
||||
- Win Rate >= 55%
|
||||
- Profit Factor >= 1.3

## 🔄 BacktestEngine
|
||||
|
||||
### Fonctionnalités
|
||||
|
||||
#### 1. Simulation Réaliste
|
||||
|
||||
```python
|
||||
✅ Coûts de transaction:
|
||||
- Commission: 0.01% par défaut
|
||||
- Slippage: 0.05% par défaut
|
||||
- Spread: 0.02% par défaut
|
||||
|
||||
✅ Gestion des ordres:
|
||||
- Entry avec slippage
|
||||
- Stop-loss automatique
|
||||
- Take-profit automatique
|
||||
- Commission sur entry et exit
|
||||
|
||||
✅ Risk management:
|
||||
- Validation pré-trade
|
||||
- Position sizing
|
||||
- Drawdown monitoring
|
||||
- Circuit breakers
|
||||
```
|
||||
|
||||
#### 2. Pas de Look-Ahead Bias
|
||||
|
||||
```python
|
||||
# Données jusqu'à barre actuelle uniquement
|
||||
for i in range(50, len(df)):
|
||||
historical_data = df.iloc[:i+1] # Pas de données futures
|
||||
signal = strategy.analyze(historical_data)
|
||||
```
|
||||
|
||||
#### 3. Equity Curve
|
||||
|
||||
```python
|
||||
# Enregistrement à chaque barre
|
||||
self.equity_curve.append(portfolio_value)
|
||||
|
||||
# Permet calcul métriques précises
|
||||
```

## 🎯 Workflow Complet
|
||||
|
||||
### 1. Développement
|
||||
|
||||
```python
|
||||
# Créer stratégie
|
||||
strategy = IntradayStrategy(config)
|
||||
```
|
||||
|
||||
### 2. Backtesting
|
||||
|
||||
```python
|
||||
# Backtest sur historique
|
||||
engine = BacktestEngine(strategy_engine, config)
|
||||
results = await engine.run(['EURUSD'], '1y', 10000)
|
||||
|
||||
# Vérifier résultats
|
||||
if results['is_valid']:
|
||||
print("✅ Pass to paper trading")
|
||||
else:
|
||||
print("❌ Optimize strategy")
|
||||
```
|
||||
|
||||
### 3. Optimisation (si nécessaire)
|
||||
|
||||
```python
|
||||
# Optimiser paramètres avec Optuna
|
||||
# Walk-forward analysis
|
||||
# Monte Carlo simulation
|
||||
```
|
||||
|
||||
### 4. Paper Trading
|
||||
|
||||
```python
|
||||
# 30 jours minimum
|
||||
paper_engine = PaperTradingEngine(strategy_engine, 10000)
|
||||
await paper_engine.run()
|
||||
|
||||
# Vérifier après 30 jours
|
||||
summary = paper_engine.get_summary()
|
||||
if paper_engine._is_ready_for_production(summary):
|
||||
print("✅ Ready for live")
|
||||
```
|
||||
|
||||
### 5. Production
|
||||
|
||||
```python
|
||||
# Lancer en live (après validation)
|
||||
await strategy_engine.run_live()
|
||||
```

## 💡 Utilisation Recommandée
|
||||
|
||||
### Workflow Standard
|
||||
|
||||
```python
|
||||
# 1. Backtest (rapide)
|
||||
results = await backtest_engine.run(['EURUSD'], '1y', 10000)
|
||||
|
||||
# 2. Si valide → Paper trading (30 jours)
|
||||
if results['is_valid']:
|
||||
await paper_engine.run()
|
||||
|
||||
# 3. Si paper trading OK → Production
|
||||
summary = paper_engine.get_summary()
|
||||
if paper_engine._is_ready_for_production(summary):
|
||||
await strategy_engine.run_live()
|
||||
```
|
||||
|
||||
### Critères de Décision
|
||||
|
||||
```
|
||||
Backtest:
|
||||
- Sharpe >= 1.5 ✅
|
||||
- Max DD <= 10% ✅
|
||||
- Win Rate >= 55% ✅
|
||||
→ Pass to Paper Trading
|
||||
|
||||
Paper Trading (30 jours):
|
||||
- Performance stable ✅
|
||||
- Pas de bugs ✅
|
||||
- Métriques confirmées ✅
|
||||
→ Pass to Production
|
||||
|
||||
Production:
|
||||
- Monitoring 24/7 ✅
|
||||
- Alertes actives ✅
|
||||
- Risk management strict ✅
|
||||
```
