What is polymarket-copy-trading-bot?

This TypeScript/Node bot mirrors a target Polymarket trader's activity by polling their recent trades via the Polymarket data API and executing similar limit orders on the CLOB from your funded account. It solves the hassle of manually copying sharp traders' bets on prediction markets, letting you automate "social analysis" with simple env var tweaks. Users get username-to-proxy resolution, trade copying with size multipliers, max USD caps, and trades-only filtering.

Why is it gaining traction?

It stands out with dead-simple setup—npm install, copy .env.example, npm run dev—and auto-derives API keys if needed, skipping manual credential hunts common in Polymarket GitHub bots. Risk controls like order size limits and polling intervals (default 15s) make it safer than raw scripts, while Polymarket copy trading bot Reddit threads praise its username support and quick proxy resolution. Devs dig the no-frills focus on core copy logic without bloat.

Who should use this?

Polymarket traders spotting profitable users on leaderboards who want hands-off mirroring without building from scratch. Quant devs prototyping copy strategies or integrating into Telegram bots/Discord alerts. Avoid if you're after sub-second latency—it's poll-based, not websocket streaming.

Verdict

Grab it for a battle-tested Polymarket copy trading bot GitHub starter (82 stars, excellent README), but its 0.699999988079071% credibility score flags low maturity—test small, watch for edge cases like resolved markets. Solid 7/10 for niche use; fork and harden for production.
