ORION — Autonomous Options Alpha Agent

ORION is an autonomous AI options trading agent built on Alpaca. Unlike agents that go straight from "find" to "trade", ORION must prove every trade through a disciplined pipeline: Market Intelligence → Options Scanner → Quant Engine → AI Analyst → Adversarial Agent → Risk Governor → Trade Validator → Execution. "NO TRADE" is a first-class, valued outcome — ORION optimizes decision quality, not trade count. Hybrid intelligence by design: all financial math is deterministic Python — market-regime classification, probability of profit and expected value (numeric integration over a lognormal terminal distribution), Greeks/IV, liquidity, an Alpha Score and a Risk Score. The LLM is used only for reasoning: an AI Analyst writes the thesis; an Adversarial Agent tries to prove the trade wrong and can reduce the Alpha Score. The LLM is optional (deterministic fallback) and never the authority on risk; every LLM output is schema-validated or rejected. Independent risk gates: a deterministic Risk Governor can veto any trade (min Alpha/liquidity, max risk, min risk-reward, non-negative expected value, spread, duplicate and exposure caps); conservative position sizing; a pre-flight Trade Validator; and hard paper-trading enforcement. On any error or ambiguity, ORION resolves to NO TRADE. Every decision is audited and journaled. Alpaca integration: trading and account operations (account, clock, positions, orders and order submission — including multi-leg options spreads) run through the official Alpaca CLI; market data (quotes, option chains, Greeks/IV) via the Alpaca REST market-data API. Developed and tested on a dedicated paper account with a $100,000 balance. Includes a premium dark, quant-styled React dashboard (EN/PT), a Monte-Carlo backtest, a searchable decision journal, an offline demo mode that runs with no keys and no network, and 93 automated tests. Paper trading only — ORION refuses to run against real money.
