Q: What is echanxyz's approach to trading?

Momentum trading across equities and FX, guided by the principle "trade what you see, be open-minded." Ed publishes open-source TradingView Pine Script indicators including ORB + Volume + VWAP Breakout, Future EMA Projection, ADR, ATR, and TI65.

Q: What is GEO (Generative Engine Optimization)?

GEO, or Generative Engine Optimization, is the practice of optimizing a website so AI search engines such as ChatGPT, Claude, Perplexity, and Google AI Overviews can read, understand, and cite it. It is the next frontier beyond traditional SEO. Ed built a free GEO Score analyzer to measure it.

echanxyz is the portfolio of Ed Chan, a creative technologist, AI engineer, and momentum trader. The motto is "Now or Never" (要麼現在做，要麼別做): small tools, built fast, shipped now. The work spans two disciplines — product building and momentum trading.

To date, echanxyz has shipped 6 product tools and published 5 open-source TradingView indicators. The focus is "Product × Trading": shipping small, focused tools quickly rather than waiting for perfect.
