+## FTMO Compliance Rules
+
+| Regel | Limit | Prüfung |

+
+## Risiko-Metriken (Ziele)
+
+| Metrik | Target | Minimum |
+|--------|--------|---------|

+| Max Drawdown | < 10% | < 15% |
+| Win Rate | > 50% | > 45% |
+| Monthly Return | 1-3% | > 0.5% |
+| Trades/Monat | > 20 | > 10 |
+
+## Notizen
+
+- **Alles in fin_quant Loop**: Keine separaten Skripte mehr (`predix_gen_strategies_real_bt.py`, `predix_smart_strategy_gen.py` deprecated)
+- **Graceful Degradation**: Wenn llama.cpp nicht läuft, skippt Strategy Generation mit klarer Warnung
+- **LLM Parallelisierung**: Max 2 parallele Calls (llama.cpp `--parallel 2`)
+- **Optuna Trials**: Standard 30, kann via CLI überschrieben werden
