AI Summary

This is an open-source trading bot that automates buying and selling on Polymarket, a crypto prediction market. It watches live prices for UP/DOWN markets on Bitcoin, Ethereum, Solana, and XRP, then automatically executes trades based on rules you set. You can choose between a simple exit-only strategy or a more advanced strategy that enters new positions, exits them, and even swaps to the opposite side. The bot connects to your crypto wallet, monitors prices every second, and places real orders on the Polygon blockchain. It includes clear warnings that this involves real financial risk and is meant for educational purposes.

What is trading-bot?

This is an open-source TypeScript bot that automates trading on Polymarket's crypto prediction markets. You configure a strategy in a TOML file, point it at a wallet with USDC on Polygon, and it buys or sells UP/DOWN tokens based on price and time thresholds. The bot polls live CLOB prices every second, makes rule-based decisions, and executes FAK orders against real on-chain balances. Two strategies are available: trade_1 exits existing positions only, while trade_2 can enter new positions, exit on defined ranges, and perform emergency swaps to the opposite side.

Why is it gaining traction?

Polymarket's CLOB API has opened up programmatic trading on prediction markets, but most tools are either Python scripts or poorly documented. This project provides a clean TypeScript implementation with actual wallet integration (including Gnosis Safe/proxy support) and production-oriented features like retry logic, balance polling, and live portfolio logging. The configurable time windows for BTC, ETH, SOL, and XRP markets give traders flexibility across short-term and daily horizons. Developers searching for polymarket trading bot github or polymarket arbitrage bot github will find a working starter with real order execution, not just pseudocode.

Who should use this?

Traders already familiar with Polymarket's market structure who want to automate mechanical strategies like "exit when price moves 95% from center" or "enter when time remaining crosses 70%." Developers building polymarket trading strategies or testing arbitrage hypotheses will benefit from the observable trading loop. Not suitable for non-crypto traders or those expecting a UI dashboard.

Verdict

The project is functional and better documented than most trading bot github repositories, but with 82 stars and a credibility score of 0.699%, it remains unproven at scale. Start with a $1-$3 trade_usd and observe several market cycles before risking real capital. The TypeScript foundation and CLOB client integration are solid; the risk is that a small, single-maintainer project may not keep pace with Polymarket API changes or handle edge cases in volatile markets.
