Build a Polymarket arbitrage bot with real-time order books, fee-aware execution, risk controls, and production-ready Python architecture.
Introduction
A useful Polymarket arbitrage bot is not simply a script that checks whether two prices add up to less than $1.
The difficult part is turning a theoretical pricing discrepancy into an executable trade after accounting for fees, spread, available liquidity, partial fills, stale quotes, execution failure, and inventory risk.
Polymarket's current production trading stack uses CLOB V2. The official Python client is py-clob-client-v2, while real-time market data is available through the public WebSocket market channel. ([Polymarket Documentation][1])
