Henry Zhang. I build FST (Full Self Trading): an AI agent that trades a paper account live every weekday from the US open and explains each decision out loud. Two signal sources have to agree before an entry, and the stop is set before the fill.

Watch it live (one page, every platform): https://quantsignals.xyz/live

Around it I build small trading tools: KATY (model forecasts drawn on TradingView charts), a live options-flow board, and a few more at https://quantsignals.xyz

Paper: Hard to Fool, an LLM research loop for quant finance built to say no (arXiv 2611.06607): https://arxiv.org/abs/2611.06607

Interested in agents that act in the real world, how to evaluate them, and building in public.
