# Polymarket backtesting and replay tools

Replay a strategy or recorded execution, compare scenarios and inspect modeled fills. Choose the engine for the past-period question you want to investigate.

How to choose backtesting

## Read the replay assumptions

The result depends on the window and the engine’s treatment of the data. Reconstructed fills should be understood through those assumptions, rather than treated as a record of what your account would necessarily have earned.

## Check the model

-   Confirm the replay window.
-   Inspect fees and spread handling.
-   Read how missing data and available depth affect modeled fills.
-   Find raw inputs in Historical data and forward simulations in Paper trading.
