🎯 SESSION FILTER PATCH - TradingBot V1.6 to V1.7
Optimiert Trading basierend auf Performance-Analyse

ÄNDERUNGEN:
1. Deaktiviert Asian Session (25.6% Win-Rate, -$199 Verlust)
2. Aktiviert nur NY + Overlap (beste Performance)
3. Optional: London Session (Break-Even)

PERFORMANCE-IMPACT:
- Asian ausschalten: -$199 eliminiert
- Nur NY+Overlap: +$581 (49% mehr Profit)
- Win-Rate: 30.9% → ~38%

📋 ANLEITUNG - Wie den Patch anwenden:

SCHRITT 1: Dieses File ins gleiche Verzeichnis wie das Notebook kopieren

SCHRITT 2: In Cell 24 (Adaptive Scheduler) folgendes ändern:

VORHER:
```python
def adaptive_trading_check():
    try:
        optimal_interval = rhythm_manager.calculate_optimal_interval()
        ...
```

NACHHER:
```python
# Importiere Session Filter
from session_filter_patch import (
    adaptive_trading_check_with_session_filter,
    SESSION_WHITELIST_CONFIG,
    is_session_allowed
)

# Alias für Kompatibilität
adaptive_trading_check = adaptive_trading_check_with_session_filter
```

SCHRITT 3: Scheduler neu starten

SCHRITT 4: Teste mit verschiedenen Modi:

# Standard Mode (NY + Overlap)
SESSION_WHITELIST_CONFIG['enabled_sessions'] = {
    'asian': False, 'london': False,
    'overlap': True, 'ny': True
}

# Aggressive Mode (nur NY, 50% Win-Rate!)
SESSION_WHITELIST_CONFIG['aggressive_mode'] = True

# Conservative Mode (alles außer Asian)
