About
I'm Ethan Lim.
This site is a record of my attempts to understand markets and build better systems.
The long-term goal is to build a serious algorithmic trading platform — combining research, data, execution, risk management, automation, and AI-assisted workflows.
The posts here are working notes from that process: market views, technical logs, models, mistakes, experiments, and frameworks that may become useful over time.
This blog is not a finished product.
It is the log of the long build.
