What you'd actually be trading here
EventTrader is a prediction exchange: perpetual prediction markets on crypto, stocks and macro moves with no expiry, live central-limit order books, event markets on real-world outcomes, and a marketplace of trading bots you can clone instead of coding. Position risk is capped at what you put in — no liquidation engine, no margin calls. Server-side alerts and free webhook auto-execution come with every account.
- Free means free. No card required. Nothing auto-converts into a paid plan.
- We are not a market-data vendor. The API serves EventTrader's markets and signals — generous and documented, but not a general data feed.
- No predictions sold. Markets are markets; we make no performance claims.
- Leave in one click. Withdraw on-chain any time, with a tx hash you can verify.
