# WinWeatherBot

> WinWeatherBot is a Microsoft-signed Windows desktop app for trading weather markets on Polymarket. It runs a 138-model forecast ensemble (GFS, ECMWF, ICON, NOAA), weights each model by recent accuracy, and sizes positions with correlation-aware and Kelly logic before submitting orders to Polymarket's CLOB API. It is self-custody: your Polymarket key stays sealed in the Windows Keyring and never leaves your machine.

Key facts: Windows 10/11 desktop application · 138-model probabilistic ensemble · correlation-aware Kelly sizing · self-custody, Microsoft-signed binary · trading modes: manual, autopilot, mispricing hunter, VPS 24/7 · paper-trading included · plans from $39/mo, one license for up to 3 devices, 7-day money-back. WinWeatherBot is a software tool, not financial advice; trading prediction markets involves substantial risk of loss, including total loss of capital. Past performance does not guarantee future results.

## How it works

- [The signal engine](https://winweatherbot.com/#how): Pull (ingest 138 model runs every ~5 min) → Resolve (map each Polymarket market to its station, time and threshold) → Score (calibrated probability, Brier-weighted) → Compare (edge vs live order-book mid-price, Kelly-sized, submitted to the CLOB).

- [Trust & security](https://winweatherbot.com/#trust): Microsoft-signed binary, credentials sealed in Windows Keyring, self-custody: the bot holds trading permissions only, never custody or withdrawal rights.
