 Sample Weather Strategy Logic

python

# Step 1: Get ensemble forecast

forecast = get_ecmwf_forecast(city="London", days=1)

forecast_prob = calculate_probability(forecast, threshold=50)

# Step 2: Get Polymarket price

market_price = get_polymarket_odds(city="London", temp_threshold=50)

# Step 3: Calculate edge

edge = forecast_prob - market_price

# Step 4: Execute if edge > threshold (e.g., 8%)

if edge > 0.08:

size = calculate_kelly_size(edge, capital)

place_limit_order(side="YES", size=size, price=market_price + 0.01)
