Risk Management for Polymarket Bots (Stop-Losses & Limits)
Automation cuts both ways: a bot follows its rules tirelessly, including the bad ones. Without hard risk controls, a single bug or bad market can drain an account fast. Risk management is what makes automation safe enough to trust.
Why automation makes risk controls essential
A human notices when something feels wrong and stops. A bot does not — it will happily repeat a losing action thousands of times. That is exactly why risk limits must be coded in, not left to judgment.
Core controls every bot should have
Per-trade and per-market exposure limits
Cap the size of any single position and the total you will hold in one market. This bounds the damage from one bad trade or a market that turns illiquid. Tie sizing to position-sizing rules.
Daily and weekly loss limits
If cumulative losses hit a threshold, the bot stops trading until you review. This prevents a bad day from becoming a catastrophic one.
Stop-losses (with nuance)
Stop-losses help, but in prediction markets they are not guaranteed. In thin or fast markets a stop can fill far worse than its trigger price (slippage), and a market can gap straight through it. A stop reduces risk; it does not cap it precisely.
A kill switch
One control that immediately halts all trading and optionally flattens positions. The most important safety feature a bot can have for when something is clearly wrong.
Correlated exposure
Two positions in “related” markets can be the same bet in disguise. A risk system should track correlated exposure so the bot does not unknowingly concentrate risk across markets that move together.
Test your risk logic before going live
Risk controls are code, and code has bugs. Backtest and forward-test that limits actually trigger — deliberately push the bot toward a limit at tiny size and confirm it stops. An untested kill switch is not a safety feature.
A risk-control checklist
- Per-trade and per-market size caps.
- Daily / weekly loss limits that halt trading.
- Stop-loss logic (understanding its limits).
- Correlated-exposure tracking.
- A tested kill switch.
- Alerts when any limit is approached (monitoring).
PolyBot ships with exposure caps, daily loss limits, and a one-click kill switch built in, so these controls run on every trade by default.
