AI-Generated Review

What is Polymarket-copy-trading-bot?

This TypeScript bot monitors a target wallet on Polymarket and copies its open positions by placing matching BUY or SELL orders on the CLOB via the Polymarket trading API. Set a TARGET_ADDRESS in .env, toggle COPY_TRADING_ENABLED, add your PRIVATE_KEY, and run with npm dev—dry run mode lets you test without risk. It polls positions every 2 seconds by default, scaling sizes with POSITION_SIZE_MULTIPLIER and enforcing min/max trade limits, solving the hassle of manually shadowing expert traders on prediction markets.

Why is it gaining traction?

Unlike scattered Polymarket GitHub SDKs or Rust/Python clones, this offers one-command setup for copy trading, with monitor-only mode and safety knobs like MAX_POSITION_SIZE to cap exposure. Devs dig the Telegram support channel and clear README with screenshots, plus GTC limit orders that persist without babysitting. Searches for "polymarket copy trading bot reddit" or "telegram" often land here for its plug-and-play vibe over raw websocket hacks.

Who should use this?

Polymarket traders copying whale addresses to automate bets on elections or events. Polygon devs prototyping trading apps or bots needing a CLOB baseline. Quant hobbyists tweaking multipliers for position sizing without building from the Polymarket GitHub API scratch.

Verdict

Grab it for dry-run experiments—98 stars and solid README make it dev-ready, but the 0.699999988079071% credibility score flags early-stage risks like polling-only detection and restart state loss. Test small before live trades; fork and add websockets for production.
