AI Summary

This is an automated trading bot for Polymarket prediction markets. It connects to your cryptocurrency wallet and watches crypto price movements (Bitcoin, Ethereum, Solana, XRP) on Polymarket's trading system. The bot follows one of two configurable strategies to automatically buy and sell prediction tokens—betting on whether prices will go up or down. It monitors markets every second, makes trading decisions based on price trends and timing rules you set, and executes trades automatically. The bot tracks your cash balance and positions, handles errors gracefully, and runs continuously through successive market windows.

How It Works

1
💡 You discover prediction market trading

You hear about Polymarket's crypto prediction markets where you can bet on whether Bitcoin, Ethereum, or other coins will go up or down.

2
⚙️ You set up your trading preferences

You choose which cryptocurrency to follow (Bitcoin, Ethereum, Solana, or XRP) and how long each market window lasts (5 minutes to 24 hours).

3
🔑 You connect your wallet

You safely connect your cryptocurrency wallet so the bot can make trades on your behalf when opportunities arise.

4
📊 The bot watches the markets

Every second, the bot checks the current prices and calculates whether the market is trending up, down, or staying flat.

5
The bot decides what to do
📈
Strategy 1: Price range trading

Bot enters when prices are in a specific range and exits when time runs out or profit targets are hit.

⚡
Strategy 2: Smart timing

Bot waits for the right moment, then enters and can even swap to the opposite position if conditions change.

6
💰 Trades happen automatically

When conditions match your settings, the bot buys UP or DOWN tokens and later sells them to lock in profits or cut losses.

🎉 Your portfolio grows

The bot continuously runs through market windows, tracking your cash and positions while you focus on other things.

AI-Generated Review

What is arbitrage-trading-bot?

This is a Polymarket trading bot written in TypeScript that automatically bets on short-term crypto price movements. It connects to Polymarket's CLOB API, polls live prices, and executes buy/sell orders based on two configurable strategies. The bot targets BTC, ETH, SOL, and XRP prediction markets across multiple time windows ranging from 5 minutes to 24 hours, with all strategy parameters defined in a simple TOML config file.

Why is it gaining traction?

Prediction market arbitrage is a growing niche, and this bot makes the mechanics accessible to developers who want to experiment without building from scratch. The dual-strategy approach gives users a choice between a straightforward exit-on-threshold model or a more complex entry-and-swap pattern. Configuration via TOML means you can tweak trade size, entry ranges, take-profit, and stop-loss without touching code.

Who should use this?

- Developers exploring crypto prediction markets who want a working starting point - Traders comfortable with Polymarket's API who need an automated execution layer - Builders evaluating prediction market mechanics for larger projects

Not suitable for production trading without significant validation, as the codebase lacks documentation, tests, and error handling for edge cases.

Verdict

At 46 stars with no README, tests, or clear documentation, this is an experimental playground, not a production tool. The credibility score of 0.699% reflects that reality. Worth exploring as a learning resource or proof-of-concept, but do your own audit before deploying with real funds.
