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 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) "API key invalid" Get new key from simmer.markets/dashboard โ SDK tab
