Coming to take over U.S. stocks, I built an Industry Chain Research Agent platform, looking for transmission logic within the industry chain, identifying the bottleneck sectors. Last year was the inaugural year of vibe coding, this year is the inaugural year of agent harness, learning by doing, building agent harness 🧐

Recent development projects:
1. Rewrote the order placement engine of the exchange using RUST, achieving faster speeds with fewer resources by placing orders based on anchoring quotes and order book imbalance features. 24/7 continuous price updates without gaps. A single 8-core 16GB server can handle approximately 100 trading pairs simultaneously, reducing arbitrage opportunities on the exchange;
2. Reconstructed the market maker's financial system with complete reconciliation logic, daily profit and loss attribution, and detailed hedge transaction data that is auditable;
3. Developed a market

After testing over 90 factors, I ultimately retained two factors—one for screening and one for filtering. With some additional experience-based optimization, I am quite satisfied with the results. Most people lack extensive trading experience and are not advised to burn tokens on timing strategies or to develop seemingly sophisticated machine learning price predictions. Instead, it’s better to let AI act like a researcher, digging into research papers to identify factors and develop factor-neutral strategies.

These past few days, I've been heavily using Codex GPT-5.2. For the first time, ChatGPT Pro members are concerned about quota limits, while Claude Codex Max hasn't been used for two days.

In Codex CLI, you can't see GPT-5.2. Use the following command to unlock it, and it's really much more powerful. Go try it now!
