A GitHub repo aggregates free, open-source quantitative finance tools—pricing engines, backtesters, order books, and HFT simulators—typically guarded by firms, including Microsoft's AI quant platform.
XAlpha introduces a memory-driven AI quant researcher that integrates financial knowledge and discovery feedback to automate the full hypothesis-to-code alpha discovery loop, achieving stronger performance on CSI300.
AI Trader is a fully autonomous trading agent now available for free.
The article summarizes the core learning methodology of world-class geometer and quantitative king James Simons: incubation by the subconscious, stripping away noise, and an extreme aversion to rote memorization, emphasizing deep thinking, leaving mental space, and cross-disciplinary learning through leveraging networks of genius.
A tweet highlights Stanford professor Stephen Boyd's free convex optimization course and textbook, noting that Citadel pays $400K for this skill. The course teaches optimal portfolio allocation, but emphasizes that the optimizer only works with a genuine edge in signals.
An educational thread explaining the mathematical foundations used by quantitative trading firms like Renaissance Technologies, covering concepts from Bernoulli to Brownian motion.
This paper introduces OpenFinGym, a unified multi-task gym environment for evaluating large language model agents in quantitative finance, covering forecasting, market generation, real-time trading, and fraud detection with verifiable execution and automated task construction.
Awesome Quant AI is a curated GitHub repository that organizes resources for AI and machine learning in quantitative finance and trading, including strategy design, trading paradigms, and frontier AI topics like LLM agents and time-series foundation models.
This article details how a systematic fund replaced its traditional NLP pipeline with a RAG-based LLM agent architecture, achieving a 340% improvement in alpha generation from unstructured data. It cites recent research (Alpha-GPT 2.0, FinCon, FinAgent) showing significant gains in automated factor discovery and trading performance.
This research tests whether Benjamin Graham's classical value investing rules can act as a mathematical 'low-pass filter' to prevent modern machine learning models (XGBoost, AutoGluon) from overfitting to market noise. Using 20 years of S&P 500 data, the authors find that Graham's rules combined with Random Forest achieve high returns with lower risk than complex AI models alone.
A comprehensive guide explaining the Kalman filter and its application in building smarter trading systems, including mathematical foundations and production-grade examples.
A thread introducing Loop Engineering as a solution to the common problem of quant strategies that backtest perfectly but fail in live trading, emphasizing the need for iterative optimization.
This paper introduces CARLOS, a deep reinforcement learning algorithm that learns continuous-time optimal stopping rules for American-style options using an aggregate deep neural network, effectively closing the Bermudan-American value gap with high computational efficiency.
Recommend 11 high-quality open-source projects on GitHub covering AI agent frameworks, AI programming, memory systems, research automation, and quantitative investment tools, designed to help developers get started quickly and boost efficiency.
A Chinese quantitative finance tutorial for absolute beginners, using Jupyter Notebook format, containing 4 chapters (quantitative cognition, return analysis, dual moving average strategy, and strategy backtesting). Uses yfinance to fetch real data, each chapter can be run through in about 30 minutes.
PandaAI proposes a closed-loop neuro-symbolic LLM agent for sequential decision-making in quantitative finance, integrating market regime modeling and constrained alpha generation to address low SNR and non-stationarity in financial data, achieving significant improvements over state-of-the-art time-series models.
A programmer earning $385,000 per year failed his interview at Jane Street for refusing to use Claude Code, reflecting that AI tools have become industry entry standards. On Polymarket, there are bets on the penetration speed of AI tools.
This tweet introduces three financial/engineering tools open-sourced by top quantitative institutions such as Jane Street, Goldman Sachs, and J.P. Morgan: magic-trace (high-precision process tracing), gs-quant (Python package for derivatives pricing and risk management), and Perspective (real-time data visualization tool), helping quant enthusiasts gain institutional-level technical capabilities for free.
This article introduces a 50-minute video shared by a Jane Street quant trader on YouTube, covering a full roadmap for quantitative learning, including practical tips on Polymarket, which is a valuable reference for quant practitioners.
Kronos is the world's first open-source foundational large model for financial markets, trained from scratch on 12 billion real candlestick data points, supporting price prediction and volatility forecasting, far outperforming general models, and completely free and open-source.
