Hey everyone, it's your friendly neighborhood senior dev here. I'm 38, working as a full-time engineer during the week, and tinkering with AI-powered algorithmic trading bots on the weekends.
Today, I want to share a story about a subtle but potentially catastrophic bug I found in my bot. Seriously, thank goodness I caught this before deploying with real capital. The TL;DR: My Discord notifications for order confirmations weren't firing, and the culprit was a forgotten .env load across multiple Python scripts.
I think this is a pretty common pitfall when you're working on personal projects with several interconnected Python scripts.
