weather-agent

Trade Polymarket weather markets using NOAA forecasts with dynamic confidence modeling and quality filtering. Use when user wants to trade temperature markets with advanced safeguards.

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 .env file with API key
• No automatic system writes

Dependencies

text

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: tradejournal for trade logging (commented out in requirements.txt)

Network Endpoints

This skill connects to 3 endpoints:

1. 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.py line ~250-280

2. 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.py line ~200-230

3. 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.py line ~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:

1. Visit simmer.markets/dashboard → SDK tab
2. Create new API key
3. Select "Trading Only" if available
4. Never grant withdrawal rights
5. Store in .env file (git-ignored)
6. Rotate key after testing

Configuration Storage

• .env file: 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

bash

# 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:false to autostart: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

bash

# 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 autostart field in SKILL.md
• Verify with OpenClaw docs or platform UI
• Manual editing prevents accidental activation

Steps:

1. Edit SKILL.md line 5 (the metadata line)
2. Change "autostart":false to "autostart":true
3. Save file
4. Restart: openclaw restart
5. Check logs to verify scheduled runs

Manual runs only (alternative):

bash

python weather_trader_enhanced.py --live --smart-sizing

This gives full control over trade timing.

Quick Start

bash

# 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_KEY from 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

bash

# 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

1. Fetches NOAA forecasts for target locations
2. Discovers weather markets via Simmer API
3. Calculates edge using dynamic confidence model (adjusts 60-90% based on forecast timing)
4. Filters markets by quality score (liquidity, volume, time)
5. Executes trades when price < entry threshold
6. 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
