Polymarket Weather Trader
Trade temperature markets on Polymarket using NOAA forecast data. This is a template. The default signal is NOAA temperature forecasts โ remix it with other weather APIs, different forecast models, or additional market types (precipitation, wind, etc.). The skill handles all the plumbing (market discovery, NOAA parsing, trade execution, safeguards). Your agent provides the alpha.
When to Use This Skill
Use this skill when the user wants to: Trade weather markets automatically Set up gopfan2-style temperature trading Buy low on weather predictions Check their weather trading positions Configure trading thresholds or locations
What's New in v1.14.0
Fixed env var names to match autotune registry (old names still work as aliases): SIMMER_WEATHER_ENTRY โ SIMMER_WEATHER_ENTRY_THRESHOLD SIMMER_WEATHER_EXIT โ SIMMER_WEATHER_EXIT_THRESHOLD SIMMER_WEATHER_MAX_POSITION โ SIMMER_WEATHER_MAX_POSITION_USD SIMMER_WEATHER_MAX_TRADES โ SIMMER_WEATHER_MAX_TRADES_PER_RUN New tunable: SIMMER_WEATHER_SLIPPAGE_MAX โ adjustable slippage safeguard (default 15%). Set higher for research mode on illiquid markets. New tunable: SIMMER_WEATHER_MIN_LIQUIDITY โ skip markets with liquidity below this USD threshold (default 0 = disabled). Pre-filters thin markets before execution. SIMMER_WEATHER_LOCATIONS and SIMMER_WEATHER_BINARY_ONLY now exposed as autotune tunables.
v1.13.0
Binary Only Mode: New SIMMER_WEATHER_BINARY_ONLY config to skip range-bucket events (e.g., "NYC 34-35ยฐF") and only trade binary yes/no weather markets
v1.2.0
Max Trades Per Run: New SIMMER_WEATHER_MAX_TRADES config to limit trades per scan cycle (default: 5)
v1.1.1
Status Script: New scripts/status.py for quick balance and position checks API Reference: Added Quick Commands section with API endpoints
v1.1.0
Source Tagging: All trades tagged with sdk:weather for portfolio tracking Smart Sizing: Position sizing based on available balance (--smart-sizing) Context Safeguards: Checks for flip-flop warnings, slippage, time decay Price Trend Detection: Detects recent price drops for stronger signals
Setup Flow
When user asks to install or configure this skill: Ask for Simmer API key They can get it from simmer.markets/dashboard โ SDK tab Store in environment as SIMMER_API_KEY Ask for wallet private key (required for live trading) This is the private key for their Polymarket wallet (the wallet that holds USDC) Store in environment as WALLET_PRIVATE_KEY The SDK uses this to sign orders client-side automatically โ no manual signing needed Ask about settings (or confirm defaults) Entry threshold: When to buy (default 15ยข) Exit threshold: When to sell (default 45ยข) Max position: Amount per trade (default $2.00) Locations: Which cities to trade (default NYC) Save settings to environment variables Set up cron (disabled by default โ user must enable scheduling)

Quick Commands
# Check account balance and positions python scripts/status.py # Detailed position list python scripts/status.py --positions API Reference: Base URL: https://api.simmer.markets Auth: Authorization: Bearer $SIMMER_API_KEY Portfolio: GET /api/sdk/portfolio Positions: GET /api/sdk/positions
Running the Skill
# Dry run (default โ shows opportunities, no trades) python weather_trader.py # Execute real trades python weather_trader.py --live # With smart position sizing (uses portfolio balance) python weather_trader.py --live --smart-sizing # Check positions only python weather_trader.py --positions # View config python weather_trader.py --config # Disable safeguards (not recommended) python weather_trader.py --no-safeguards # Disable trend detection python weather_trader.py --no-trends # Quiet mode โ only output on trades/errors (ideal for high-frequency runs) python weather_trader.py --live --quiet # Combine: frequent scanning, minimal noise python weather_trader.py --live --smart-sizing --quiet
How It Works
Each cycle the script: Fetches active weather markets from Simmer API Groups markets by event (each temperature day is one event) Parses event names to get location and date Fetches NOAA forecast for that location/date Finds the temperature bucket that matches the forecast Safeguards: Checks context for flip-flop warnings, slippage, time decay Trend Detection: Looks for recent price drops (stronger buy signal) Entry: If bucket price < threshold and safeguards pass โ BUY Exit: Checks open positions, sells if price > exit threshold Tagging: All trades tagged with sdk:weather for tracking
Smart Sizing
With --smart-sizing, position size is calculated as: 5% of available USDC balance (configurable via SIMMER_WEATHER_SIZING_PCT) Capped at max position setting ($2.00 default) Falls back to fixed size if portfolio unavailable This prevents over-deployment and scales with your account size.
Safeguards
Before trading, the skill checks: Flip-flop warning: Skips if you've been reversing too much Slippage: Skips if estimated slippage > 15% Time decay: Skips if market resolves in < 2 hours Market status: Skips if market already resolved Disable with --no-safeguards (not recommended).
Source Tagging
All trades are tagged with source: "sdk:weather". This means: Portfolio shows breakdown by strategy Copytrading skill won't sell your weather positions You can track weather P&L separately

Troubleshooting
"Safeguard blocked: Severe flip-flop warning" You've been changing direction too much on this market Wait before trading again "Slippage too high" Market is illiquid, reduce position size or skip "Resolves in Xh - too soon" Market resolving soon, risk is elevated "No weather markets found" Weather markets may not be active (seasonal) "External wallet requires a pre-signed order" WALLET_PRIVATE_KEY is not set in the environment The SDK signs orders automatically when this env var is present โ no manual signing code needed Fix: export WALLET_PRIVATE_KEY=0x<your-polymarket-wallet-private-key> Do NOT attempt to sign orders manually or modify the skill code โ the SDK handles it "Balance shows $0 but I have USDC on Polygon" Polymarket uses USDC.e (bridged USDC, contract 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174) โ not native USDC If you bridged USDC to Polygon recently, you likely received native USDC Swap native USDC to USDC.e, then retry "API key invalid" Get new key from simmer.markets/dashboard โ SDK tab
