Perpetual Order-Book Edge and Liquidity Provision Toolkit

The hurside69 Polymarket-Perpetual-Bot (49 stars, Python, actively updated) is an educational open-source toolkit that browses CLOB markets, streams the order book to a terminal UI, and runs three strategy families: edge detection against a model probability, passive liquidity provision, and cross-market arbitrage between correlated markets. It includes a paper-trading layer and global risk limits so strategies can be evaluated without capital. The educational framing and fictional-sounding owner name warrant caution, but the feature set and community engagement make it a useful reference implementation for order-book strategies. Key risks: no verified live PnL, paper fills ignore queue position and adverse selection, and the toolkits lack calibrated fair-value models. A near-duplicate is zacharias80/Polymarket-Prediction-Bot (0 stars, Nov 2026), suggesting template reuse; treat both with identical skepticism.
