Twelve years is impressive.
The site going dark mid-run wasn't.
HaasOnline has survived twelve years of crypto — with high license costs, a crypto-only scope, and a community site that went dark before its 2026 rebuild. EventTrader's bot marketplace is free, hosted server-side, with leaderboards built from real fills.
A real retail API, day one
Documented REST API with key auth on free signup — docs at /api-docs, SDK at /sdk, plus an MCP server (pip install cymetica-eventtrader-mcp).
Webhook auto-execution
Point any alert at your personal webhook endpoint and it executes on the exchange account you connect — your keys, encrypted, used for your authorized trading only, never withdrawals. Delivery is retried and confirmed: the venue's acknowledgement of your order, not a promised fill.

Clone working strategy bots from the marketplace and run them server-side — or drive your own through the API.

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 drop-in replacement for your old stack. EventTrader is a prediction exchange with a real public API — the automation is familiar, the markets are ours.
- 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.
