    • The pricing FAQ describes 30–60-second REST refreshes; Pro WebSocket support is labeled coming soon.
    • An extreme displayed spread can reflect stale or mismatched contracts rather than an executable opportunity.
    • Coverage labels include Betfair, while the live platform counter can show fewer currently active feeds.
    • Enterprise stream availability is contractual.

    Our take on PredRadar

    Cross-venue discovery and closing-date context support broad monitoring. REST refresh intervals and still-planned WebSockets limit real-time use, and flagged gaps require contract-level comparison.
