|
|
```
|
|
|
|
### 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%

## 🔄 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:
|
|

|
|
- Stop-loss automatique
|
|
- Take-profit automatique
|
|
- Commission sur entry et exit
|
|
|
|
✅ Risk management:
|
|

|
|
```
|
|
|
|
#### 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 ✅
|
|
```
