# Data and limitations

> Where the data comes from, and what it is not.

## Sources

Routeur reads each venue's **public** market data: listings and contract terms, top-of-book asks, order books when sizing leads, and public trade feeds. It does not trade, hold accounts on your behalf, or see anyone's identity: no account or wallet is recorded with a trade.

Settled history for Kalshi comes from Kalshi's archive. Polymarket history from before recording began was imported from an earlier record and is marked `archive` wherever it appears.

## What the data is

* **Observations, not quotes.** Prices are what a venue was asking when it was read. They can move before your order reaches the venue.
* **Proofs, not predictions.** A relation says how two contracts' outcomes constrain each other. It says nothing about which way either will resolve.
* **History, not forecasts.** Calibration and strategies describe what settled markets did. Past gaps can close.

| Polymarket history | Settled Polymarket markets are still few, so its calibration bands and strategies are thin.                            |
| Fees               | Estimated from published schedules; venues can change them.                                                            |
