Polymarket Paper Trading vs Backtesting: Which Comes First?
Compare Polymarket paper trading and backtesting, including when to use each and why historical order book replay should come before live simulation.
Polymarket paper trading and backtesting answer different questions. Backtesting asks whether a strategy worked across historical resolved markets. Paper trading asks whether the live implementation behaves correctly now.
Comparison
| Method | Best for | Main weakness |
|---|---|---|
| Backtesting | Testing many resolved markets quickly | Depends on data quality and fill assumptions |
| Paper trading | Testing live infrastructure | Slow sample collection and no known outcome yet |
Recommended Order
- Backtest on resolved markets.
- Stress-test slippage and order size.
- Paper trade live signals without capital.
- Deploy small and monitor fill quality.
Why Backtesting Comes First
Backtesting lets you evaluate hundreds or thousands of historical markets before waiting for new live samples. Paper trading is still useful, but it should validate implementation after the strategy has earned the right to be tested live.
