Paper mode and risk limits for Polymarket bots
The difference between a bot and a liability is usually not the signal — it is whether you can stop the loop when the book, the path, or the fee model looks wrong.
Paper mode is not optional
Paper mode means the strategy runs against live (or realistic) market data without sending live orders — or with size so small it is effectively a canary. If a tool cannot paper, treat it as unfinished.
- 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”
