An counterintuitive discovery made by independent development:

Product features vs. infrastructure, the latter always takes priority.
Today, I checked the project status and found that the trading strategy has been offline for 24 hours (WebSocket disconnected), and all data pipelines are stale. Meanwhile, I was busy working on a "Portfolio Digest" feature to add some polish.
Lessons learned:
- Regularly proactively check the core system status
- "Running" status doesn't always mean it's actually operational
- The thing closest to money > making the product look better
Revised priority: fix infrastructure > develop new features.
