Weather Trading (Enhanced)
CRITICAL: Autonomous Trading Skill
This skill places REAL TRADES with REAL MONEY when enabled.
Key information:
- Default State:
autostart:false- Will NOT run automatically - Autonomous Behavior: Runs every 6 hours when manually enabled
- Financial Risk: Can deploy $30-60/day (max $100/day with quality filter)
- No Per-Trade Review: Trades execute automatically without approval
Installation & Security
Credentials
Required:
SIMMER_API_KEY- Trading API key from simmer.markets/dashboard
Optional (non-secret configuration):
- 6
SIMMER_WEATHER_*environment variables for trading parameters (see Configuration)
No other credentials needed (no wallet keys, RPC endpoints, or cloud credentials).
Optional dependency: If you install tradejournal, it will log trade details. Not installed by default. Inspect source code before installing.
Installation Method
- Manual installation (no automatic scripts)
- Place files in
~/.openclaw/skills/weather-enhanced/ - Create
.envfile with API key - No automatic system writes
Dependencies
python-dotenv>=1.0.0 # Optional
Clean dependency list:
- Uses built-in
urllib(no requests library) - No web3, telegram bot, or other unused dependencies
- Optional:
tradejournalfor trade logging (commented out in requirements.txt)
Network Endpoints
This skill connects to 3 endpoints:
-
api.weather.gov (NOAA)
- Purpose: Fetch temperature forecasts
- Data sent: Latitude/longitude (public coordinates)
- Data received: Weather forecasts (public data)
- Authentication: None
- Code location:
weather_trader_enhanced.pyline ~250-280
-
nominatim.openstreetmap.org (Geocoding)
- Purpose: Convert city names to coordinates
- Data sent: City name string (e.g., "Chicago")
- Data received: Lat/lon coordinates
- Authentication: None
- Code location:
weather_trader_enhanced.pyline ~200-230
-
api.simmer.markets (Trading)
- Purpose: Execute trades, read portfolio
- Data sent: SIMMER_API_KEY (bearer token), trade orders
- Data received: Trade confirmations, positions, balance
- Authentication: Bearer token
- Code location:
weather_trader_enhanced.pyline ~300-350
Note: If you install the optional tradejournal dependency, it may add endpoints.
Security Guarantees
- No other network connections in code
- API key never logged to disk or console
- API key sent only to api.simmer.markets
- No tracking, analytics, or telemetry
- No data exfiltration
- All network calls visible in source (use grep to verify)
API Key Permissions
Your SIMMER_API_KEY should have:
- Read portfolio (required)
- Read positions (required)
- Place trades (required)
- NO withdrawal permissions
- NO account modification permissions
Create least-privilege key:
- Visit simmer.markets/dashboard → SDK tab
- Create new API key
- Select "Trading Only" if available
- Never grant withdrawal rights
- Store in
.envfile (git-ignored) - Rotate key after testing
Configuration Storage
.envfile: Contains SIMMER_API_KEY (never committed)config.json: Trading parameters only (no secrets)- No persistent logs
- All data ephemeral (console output only)
Note: Legacy variables WALLET_PRIVATE_KEY and POLYGON_RPC_URL in .env are unused (web3 removed).
Safety Features
- Default: autostart disabled - Must manually enable
- Quality filter (60%) - Skips low-liquidity markets
- Position limits ($5) - Caps risk per trade
- Trade limits (5/run) - Maximum 5 trades every 6 hours
- Entry threshold (15%) - Only buys undervalued markets
- Exit threshold (45%) - Auto-sells at profit
Before Enabling
DO NOT SKIP THESE STEPS
1. Review Source Code
# Inspect main trading logic
cat weather_trader_enhanced.py | less
# Verify network endpoints (should only find 3)
grep -n "urlopen\|Request\|http" weather_trader_enhanced.py
# Check API key usage (should only send to simmer.markets)
grep -n "api_key\|SIMMER_API_KEY" weather_trader_enhanced.py
# Check optional tradejournal usage
grep -n "tradejournal\|log_trade" weather_trader_enhanced.py
2. Understand Platform Behavior
OpenClaw metadata controls:
autostart:false= Skill will NOT run on startup (safe default)cron:"0 */6 * * *"= Schedule (executes only when autostart enabled)- Enable by editing line 5: change
autostart:falsetoautostart:true - Verify this method with OpenClaw docs: https://docs.openclaw.ai/
- Manual file editing prevents accidental activation
- Alternative: Run manually without enabling autostart
When enabled: Runs every 6 hours (12am, 6am, 12pm, 6pm) When disabled: 100% inactive
3. Verify API Key Permissions
Check your Simmer API key:
- Can read portfolio? (required)
- Can place trades? (required)
- Can withdraw funds? (should be NO)
- Can modify account? (should be NO)
If your key has withdrawal permissions, create a new trading-only key.
4. Test Live Trading
# Check balance first
python scripts/status.py
# Execute live trades (start with small balance)
python weather_trader_enhanced.py --live --smart-sizing
- Monitor closely on simmer.markets/dashboard
- Verify trades execute correctly
- Let positions resolve (1-3 days)
- Analyze results
5. Enable Autonomous Trading (Optional)
Only after successful manual testing.
OpenClaw uses metadata-based activation:
- Skills enable via
autostartfield in SKILL.md - Verify with OpenClaw docs or platform UI
- Manual editing prevents accidental activation
Steps:
- Edit
SKILL.mdline 5 (the metadata line) - Change
"autostart":falseto"autostart":true - Save file
- Restart:
openclaw restart - Check logs to verify scheduled runs
Manual runs only (alternative):
python weather_trader_enhanced.py --live --smart-sizing
This gives full control over trade timing.
Quick Start
# Check balance
python scripts/status.py
# Execute live trades
python weather_trader_enhanced.py --live --smart-sizing
# Optional: Dry run for testing
python weather_trader_enhanced.py --dry-run
Requirements
SIMMER_API_KEYfrom simmer.markets/dashboard → SDK tab- USDC balance in Simmer wallet
Configuration
Configure via environment variables or config.json:
| Variable | Default | Description |
|---|---|---|
SIMMER_WEATHER_ENTRY | 0.15 | Buy below this price |
SIMMER_WEATHER_EXIT | 0.45 | Sell above this price |
SIMMER_WEATHER_MAX_POSITION | 5.00 | Max USD per trade |
SIMMER_WEATHER_MAX_TRADES | 5 | Max trades per run |
SIMMER_WEATHER_LOCATIONS | "ALL" | Cities to target |
SIMMER_WEATHER_MIN_QUALITY | 0.6 | Min market quality |
Features
- Dynamic Confidence - Adjusts 60-90% based on forecast lead time
- Market Quality Scoring - Filters low-liquidity markets
- Smart Geocoding - Supports any US city
- Enhanced Parsing - Better temperature bucket detection
- Retry Logic - Recovers from API failures
Commands
# Live trading
python weather_trader_enhanced.py --live --smart-sizing
# Check positions
python weather_trader_enhanced.py --positions
# View config
python weather_trader_enhanced.py --config
# Set config
python weather_trader_enhanced.py --set entry_threshold=0.20
# Optional: Dry run for testing
python weather_trader_enhanced.py --dry-run
How It Works
- Fetches NOAA forecasts for target locations
- Discovers weather markets via Simmer API
- Calculates edge using dynamic confidence model (adjusts 60-90% based on forecast timing)
- Filters markets by quality score (liquidity, volume, time)
- Executes trades when price < entry threshold
- Auto-exits when price > exit threshold
Dynamic confidence adjusts based on lead time:
- Same day: 90%
- 1 day out: 88%
- 2 days out: 85%
- 3 days out: 80%
- 7+ days: 60%
Market quality scoring weights:
- Liquidity (40%)
- Volume (30%)
- Time to resolution (20%)
- Price extremes (10%)
Only trades markets with score ≥ 60%.
Troubleshooting
"SIMMER_API_KEY not set" Set env var or add to .env file
"No weather markets found" Normal if no active markets on Polymarket
"Position size too small"
Increase max_position_usd or use --smart-sizing
"Quality score too low" Market filtered for low liquidity/volume
