[ What We Offer ]
Follow every active weather market with one simple system and get an edge in the market with automated CLOB trading.
Not a web app, not a website — a real desktop application, signed and verified by Microsoft. Sensitive data like your API keys is locked down by Windows Keyring™.
Your API keys are sealed inside Windows Keyring™. Nothing ever leaves your machine: every byte stays encrypted on your own computer, never on our servers.
Auto-Update keeps the software fresh in the background — new releases install silently. For anything else, our support team has your back.
Signal: ensemble probability minus live order-book mid-price, filtered through a calibrated threshold. Position sizing is correlation-aware: per-city and per-region hard caps prevent a single weather event from stacking concentrated exposure. Volatility circuit breaker halts new entries above 3σ ensemble spread; drawdown stop triggers at a threshold you set. Methodology published — no return guarantees ever quoted.
Why retail loses
Betting on weather without the right tools gets you nowhere. Markets constantly fluctuate, and looking away for a second means you lose opportunities and get left behind by the market. WinWeatherBot gives you a clear advantage.
You can’t monitor every market and opportunity. When weather reaches the market, quant desks and algorithmic traders have already repriced it.
Your weather app silently mixes GFS, ECMWF, ICON into one number. When the models disagree, you don't see the warning. The market does.
Two correlated cities feel like two trades. They're not. One heat dome wipes out six positions before lunch and you can't tell why.
Polymarket weather markets close at the next day's high temperature. The 9 PM UTC inefficiency happens while you're at dinner.
Advanced features
Four ways to put the same engine to work — manual entries, full autopilot, mispricing hunter, or always-on on a VPS. None of these exclude the others; combine them however your trading day demands.
Use the ensemble to identify markets and positive edges and then place the bets yourself. Best for: learning polymarket systems. rkets and the positive edges yourself, then buy only what you actually want.
Set and forget. Place your controls and train the algorithm and let it work its magic. Best for: 90% of users.
Scan for edges above your threshold and take action. Best for: those who trust the model’s signal.
Run the system continuously on your Windows PC or a low-cost VPS to keep trading. Best for: 24/7 market coverage.
Why WIN Weather Bot wins
We do four things ordinary traders can't: see the model first, weight the disagreement, size by correlation, and never stop watching.
138 numerical model runs are pulled the moment each run is public: four ensemble signals (GFS, ECMWF, ICON, NOAA) plus 134 deterministic runs. Typically 15 minutes before retail apps reflect the update.
When the ensemble crosses an edge threshold, the bot submits to Polymarket's CLOB API in under 200 ms. The window of mispricing is measured in minutes.
Hard caps per city, per region, per direction. A heat dome over Europe never blows up your bankroll because the bot already knew the trades were the same trade.
Run it on your home PC or a $5 VPS. Each model run is watched, each weather window is monitored, each correlation breach is throttled — while you sleep.

Under the hood
1. Pull. Every 5 minutes the engine ingests 138 numerical weather prediction runs — four ensemble models (GFS, ECMWF, ICON, NOAA) plus 134 deterministic runs. Latency from model release to ingestion: 30 to 90 seconds, depending on feed.
2. Resolve. For each active Polymarket weather market, the engine identifies the resolution station (e.g., LFPB for Paris-Le Bourget), the resolution time, and the threshold (e.g., "high > 22°C").
3. Score. Each of the 138 runs contributes a probability that the threshold will be crossed. The four ensemble models are weighted by historical accuracy in that region and forecast horizon; deterministic runs contribute bias-correction offsets. A single calibrated probability emerges.
4. Compare. The engine reads the live Polymarket order book mid-price for that outcome token. Spread = ensemble probability − mid-price. Anything above the configured threshold becomes a candidate.

What traders say
Active users running the bot on home rigs and Hetzner VPS. Verified accounts only.
Tried three different bots before this. The 4-model ensemble is what makes the difference — when GFS and ECMWF disagree, this one knows which to weight. Flipped from a slow bleed to consistent gains in six weeks.
The position sizing logic sold me. I had blown up twice with manual betting. During the heatwave six positions correlated and the bot wouldn't let me load more — that alone paid for the annual plan.
Set it once on a Hetzner VPS in Frankfurt, forgot about it. Logged back in two months later: bankroll up 14% with zero intervention. The 24/7 unattended thing is real, not marketing fluff.
