polymarket-arbitrage-trading-bot — Claude Code skill

A skill that builds a trading bot for Polymarket's 15-minute Up/Down markets: it watches BTC, ETH, SOL and XRP and buys both legs once their combined price drops under a threshold.

What polymarket-arbitrage-trading-bot does

The bot is TypeScript, built on the official @polymarket/clob-client. At the start of each 15-minute round it watches for a sharp drop on one leg, buys that leg, then takes the opposite side if the two entries together stay under the target sum. When the opposite side never gets cheap enough in time, a stop-loss hedge fires instead.

The skill covers the entry point, price monitoring, the dump-hedge strategy module, Gamma and CLOB API calls, order placement and on-chain redemption. Simulation is the safe default: npm run sim logs trades without sending anything, while npm run prod places real CLOB orders. Everything configurable lives in .env — wallet key, signature type, market list, poll interval and strategy thresholds.

Live trading needs Node.js 16+, USDC on Polygon and a Polymarket-compatible wallet. Miss any of those and you are stuck in simulation. The threshold values shown in the config example come from the README as a starting point, not as fixed limits, so tune them to your position size.

What it helps with

  • locate the active 15-minute market for a given coin
  • catch a sharp price drop on one leg
  • buy both legs while their combined price stays under the target
  • trigger a stop-loss hedge when the second leg never cheapens
  • rehearse the strategy in simulation without real orders

Example prompts for the agent

  • Set up the Polymarket arbitrage bot for btc, eth, sol and xrp markets
  • Run the dump-and-hedge strategy in simulation mode and show me the trade log
  • Walk through the .env config and explain what each strategy threshold does
