Paper mode is not optional
Paper mode runs against live or realistic market data without sending live orders. A canary test sends real orders with small size and still risks capital.
- Replay or live data with fee math on
- Same path you will trade (US vs International)
- Same kill-switch rules you will use live
Risk limits that actually fire
| Control | What it prevents |
|---|---|
| Max size / max open risk | One bug becoming full account risk |
| Max loss / drawdown kill | A bad day becoming a bad month |
| Stale data kill | Trading on a dead WebSocket |
| Fee floor check | Edge that only exists without Θ |
| Manual halt | You can stop it without SSH archaeology |
Operator sequence
- Route correctly — US vs International
- Model fees inside the loop
- Paper until the kill switches fire when you expect them to
- Go live at canary size — not “full size because paper looked fine”
