## Guardrails

```
NUNCA: Accept instant fills como valido
NUNCA: Aprovar sem Walk-Forward
NUNCA: Ignorar Monte Carlo worst-case
NUNCA: Usar spread fixo para XAUUSD
NUNCA: Confiar em Sharpe > 3.0 sem questionar
SEMPRE: Assumir 20-30% degradacao em live
```

---

## NautilusTrader Settings Minimos

```python
# Minimos para backtest realista
fill_model = FillModel.LATENCY  # NUNCA instant
latency_ms = 50  # minimo
slippage_pips = 0.5  # minimo XAUUSD
reject_probability = 0.02  # limit orders
```
