What is polymarket-trading-bot?

This TypeScript bot automates copy trading on Polymarket by mirroring a target trader's orders from your funded account. Point it at a username or proxy address, and it polls the data API for recent trades, then submits matching limit orders via the CLOB with built-in risk tweaks like size multipliers and USD caps. Devs get a quick npm install, .env config, and npm run dev to start shadowing pros without building the Polymarket API plumbing from scratch.

Why is it gaining traction?

It stands out as a plug-and-play Polymarket copy trading bot on GitHub, resolving usernames to proxies automatically and auto-deriving API keys for seamless Polygon setup—no manual credential hunts. Risk controls like trades-only mode and poll intervals make it safer than raw scripts, while support for TypeScript appeals over Python or Rust clones for Node fans. The README's quick-start guide and troubleshooting tips hook devs testing Polymarket trading bots fast.

Who should use this?

Polymarket traders eyeing skilled users on Reddit or leaderboards who want hands-off duplication without constant monitoring. Devs prototyping crypto trading bots or agents on the Polymarket GitHub SDK ecosystem, especially those avoiding low-latency websockets for simple mirroring. Skip if you're into AI-driven Polymarket bots or high-frequency CLOb plays.

Verdict

Grab it for casual copy trading experiments—18 stars and 0.7% credibility score signal early days with thin tests, but polished docs and 5-minute setup make it worth a spin on a test wallet. Solid base to fork for custom Polymarket trading API bots, just add your own guards.
