Range: Last 10 · DEMO dataset · thresholds graded against closing lines
Only markets that exist in connected prediction-market data appear here.
Only signals timestamped and saved before kickoff are graded. Historical calls are never rewritten after results are known.
Units, ROI and closing-line value populate once graded signals are stored with entry prices. Nothing here is hidden or retroactively edited.
No trend is ever shown without its sample size.
Save players, props, markets, trends and games. The Den shows exactly how each one has moved since you saved it, and My Card tracks hypothetical units, ROI and closing-line value — no real-money wagering.
