# OddsXray

> OddsXray publishes THE DOCKET: a public, timestamped record of signals derived from Polymarket's own trade tape. A call is printed the moment the rule fires and is never edited afterwards; when the market resolves, the same line is marked hit or miss with the realised return of having followed it. Misses render exactly like hits. The complete record, the methodology and a set of prediction-market calculators are free and need no account. The paid product is real-time access to calls while they are still open.
