How it’s scored

Each forecast is compared with the market price at the moment it was made.
The error is the Brier score: the squared gap between a forecast and the result. Each market counts once.
Ranked by how far the forecast error is below the market price error.

Lower is better. 0 is perfect; always saying 50% scores 0.25.
