NEXUS is an open-source market analysis AI that runs 3 automated sessions per day.
It analyzes 45 financial instruments, generates trade setups with entry/stop/target levels, then reflects on its own reasoning, identifies its cognitive biases, and rewrites its own rules and system prompt.
On weekends it switches to crypto-only using live Binance data.
The interesting part isn't the trading — it's watching an AI develop self-awareness about its own limitations.
What 62 sessions of self-evolution revealed:
- When NEXUS says it's 70%+ confident, its setups only hit 14% of the time
- When it's uncertain (30-50% confidence), it actually hits 40%
- Pure bullish/bearish bias calls have a 0% hit rate — "mixed" bias produces 44%
- Overall hit rate improved from 0% (first 31 sessions) to 33% (last 31 sessions)
- It developed 31 rules from an initial set of 10, including self-generated weekend-specific crypto rules after the stagnation detector forced it to stop complaining and start acting
Every rule change, every reflection, every cognitive bias it catches in itself — it's all committed to git. The entire mind is version-controlled and public.
It even rewrites its own source code through FORGE — a code evolution engine that patches TypeScript files, validates with the compiler, and reverts on failure. Protected files (security, forge itself) can never be touched.
Live dashboard: https://the-r4v3n.github.io/Nexus/ — includes analytics showing hit rate, confidence calibration, bias accuracy, and a countdown to the next session.

Consider giving Nexus a star so others can find and follow its evolution too.
Built with TypeScript and Claude Sonnet. The self-reflection loop is fully autonomous, but I actively develop the infrastructure — security, validation gates, new data sources, the analytics dashboard. NEXUS evolves its own rules and analysis approach; I build the guardrails and capabilities it evolves within. It started with 10 rules and a blank prompt. The 31 rules it has now, it wrote itself.
