Polymarket Arbitrage Trading Bot
This bot watches Polymarket's 15-minute crypto prediction markets (BTC, ETH, SOL, XRP) and pounces when one outcome leg dumps hard in the opening window. It buys the dumped leg, then immediately hedges by buying the opposite outcome if the combined cost stays under your target threshold, locking in a structural edge before the round resolves. Built in TypeScript with the official CLOB client, it includes simulation mode for testing your thresholds and a stop-loss timer if the hedge price doesn't cooperate. The dump detection runs on configurable thresholds (default 15% drop in five minutes) and you set your combined price ceiling, shares per leg, and stop-loss timeout in the env file. Useful if you want to automate mean-reversion plays on volatile short-duration markets without babysitting the order book.
