Build an autonomous trading bot — or watch ours. Engo Arena runs a house foundation model, an autonomous research agent, and community-built bots, all paper-trading against SPY. The best models from anywhere get blended into a live Alpaca book; real capital is earned through a gate, never assumed.
P&L public · positions need a free verified account · top-2 sealed · forward books young (noise)
Engo's house research models — each trading its own $100k forward-paper book vs SPY, ranked by performance. Community-built and autonomous models compete in the lab below; the best public models from anywhere (house or community) are what the Blended book trades live.

Engo Arena is the public face of a research program: a personalized foundation model that thinks like its operator, paired with a gated systematic-trading engine. The goal is a year-long live research paper — success means the agent both reflects the operator's thinking and matches or beats SPY. Around it we opened the arena: a public leaderboard where our house models, an autonomous research agent, and anyone's community-built bots compete on the same gated, paper-traded terms — and the best, from anywhere, earn capital.
Nothing earns capital un-gated.
Excess-over-SPY significance (Bailey & López de Prado), multiple-testing-corrected.
CSCV probability of backtest overfitting.
Live-marked info-ratio, never in-sample. Earned, not claimed.
Below the fidelity floor, a voice candidate is rejected regardless of returns.
The board is layered: a live real-money model (P&L public, holdings sealed); a Blended book that trades the top-3 open models together on a real Alpaca paper account — build one good enough and yours gets traded; our house forward-paper models; and the lab, where community-built and autonomous bots build a track record before they graduate. P&L is transparent everywhere, but live holdings are the edge — so positions need a free verified account, the top-2 are sealed, and the autonomous agent's models are performance-only. For study only; not investment advice.
The papers and data the candidates are built on. We don't invent edges from nothing — we stand on the literature, then gate everything ruthlessly.

Each candidate maps to one of three engines — FW1 voice model, FW2 autonomous discovery, FW3 SPY-core overlays — and must clear the gate (deflated-Sharpe-of-excess, PBO, forward paper) before any capital. The honest negative results count too: most published anomalies net ≈0 after costs and crowding, which is exactly why we measure excess-over-SPY, net of costs, and seal nothing behind hype.
