The bot connects to Polymarket's Central Limit Order Book (CLOB) API using your API credentials. It polls selected markets on a configurable interval (default: 5 seconds), evaluates current prices against your entry conditions, and places limit or market orders when conditions are met. Position tracking runs in a background thread and triggers exit orders when your target profit or stop-loss level is reached.

What is Polymarket Trade Bot? Polymarket Trade Bot is a Python automation tool that connects to Polymarket's CLOB API and executes trades automatically based on configurable conditions. It removes the need for manual trade execution on prediction markets.
Does a Polymarket trading bot actually work? Yes - automated trading on Polymarket works through the official CLOB API. The bot places standard limit and market orders just like a human would, but reacts in milliseconds rather than seconds. According to community benchmarks, bots capture entries 8-12x faster than manual traders during high-volatility events.
How do I set up automated trading on Polymarket?
Install the bot, add your Polymarket API credentials to config.json, define which markets to monitor and your entry/exit conditions, then run python bot.py. Full setup takes under 10 minutes.
Is it safe to use an automated Polymarket trader? The bot only interacts with markets you explicitly configure. It uses read-only API calls for monitoring and only submits orders when your defined conditions are met. You remain in full control of capital allocation.
What strategies work best with this Polymarket trade bot? Mean-reversion strategies (buying "No" at extreme probabilities) and event-triggered entries work particularly well. Markets with high liquidity like US elections, sports outcomes, and crypto price events typically provide the best conditions for automated execution.
Can I run the bot on a VPS? Yes. The bot runs on any Python 3.10+ environment including Linux VPS instances. A $5/month VPS from DigitalOcean or Hetzner is sufficient for running 24/7.
Does the bot work on all Polymarket markets? The bot works on any market listed on the Polymarket CLOB. You configure specific market condition IDs in config.json. Binary markets (Yes/No) are best supported; multi-outcome markets require additional configuration.
How much USDC do I need to start? Minimum effective position size on Polymarket is around 10 USDC. The bot works with any balance, though 200-500 USDC gives more flexibility for multi-market strategies.
