Win Weather Bot

WIN Weather Bot is a Windows desktop application that automatically trades weather markets on Polymarket. It runs a 138-run daily forecast ensemble (GFS, ECMWF, ICON, NOAA) and prices those probabilities against Polymarket's live order book, executing in under 200 ms when the calibrated edge clears a threshold. It is 100% non-custodial: API keys are sealed in the Windows Keyring on the user's own machine, nothing touches external servers, and there is no withdrawal access. The app is Microsoft-signed. Risk controls include correlation-aware position caps, a volatility circuit breaker, and a user-set drawdown stop. Methodology is published in full and the tool quotes no return guarantees. Runs 24/7 on a PC or low-cost VPS; available wherever Polymarket is accessible.
