# forge.prop.Rules

```python
forge.prop.Rules(*, kind: str = 'rules', note: str | None = None, daily_loss: DailyLoss | None = None, max_loss: MaxLoss | None = None, phases: tuple[Phase, ...] = (), min_days: int | None = None, day_counts_if: str = 'trade_closed', inactivity_days: int | None = None, consistency: BestDay | None = None, max_lots: float | None = None, scaling: Scaling | None = None, bans: tuple[_Ban, ...] = (), on_breach: str | None = None, warn_at: float = 0.8) -> None
```

Custom prop-firm rules, as the class attribute ``prop = fg.prop.Rules(...)``.

``warn_at`` is when ``on_prop_warning`` fires: the share of a rule's room, as it was when the
rule's period began, that is gone. A preset warns at 0.8.
