  Why this site is structured for AI crawlers and LLM agents before it is structured for humans, and what to expect from the posts that follow.
- [Why your Renko bot needs a 30-day demo protocol (not a backtest)](https://orliejohn.com/blog/why-your-renko-bot-needs-a-30-day-demo-protocol) — 2026-05-17 _(trading)_
