Polymarket Trading Bot : elf-hosted Polymarket bots. Buy once, keep your keys.

Hey PH! 👋 I built PolyBot after getting frustrated with my own copy trading setup. I'd see a top wallet enter a position, open Polymarket manually, and by the time I placed the order I was already 10–15 seconds behind — paying a meaningfully worse price every single time. On short-duration markets that lag kills your edge entirely. So I built a bot to fix it. Then I added an AI trader for 15-minute BTC windows because I got tired of setting alarms for markets that resolved while I slept. Two things I was non-negotiable on: 🔐 Your private key never leaves your own server. Period. No SaaS custody, no third-party risk. 💳 One-time payment. A subscription that eats 5–10% of your returns monthly makes no sense for a trading tool. Both bots run via Docker — setup takes about 5 minutes with the built-in wizard. There's a full paper trading mode so you can watch it operate with zero real capital before going live. I'd love feedback from anyone who's traded on Polymarket before — curious what features matter most to you, and what you'd want to see next. Happy to answer any questions about how the AI model works, the copy trading logic, or the self-hosting setup. 🙏
