# echanxyz — Ed Chan

> Personal portfolio of Ed Chan (echanxyz): a product builder and momentum trader who ships small, fast tools and publishes open-source trading indicators. Motto: "Now or Never." (要麼現在做，要麼別做) — small tools, built fast, shipped now.

Ed Chan works across two disciplines: **product building** (small, focused web and native macOS tools) and **momentum trading** (equities and FX, with open-source TradingView Pine Script indicators). The site is a minimalist, monochrome single-page portfolio.
