Setup Flow

When user asks to install or configure this skill:

1. Ask for Simmer API key - They can get it from simmer.markets/dashboard → SDK tab - Store in environment as SIMMER_API_KEY

2. Ask about settings (or confirm defaults) - Entry threshold: When to buy (default 15¢) - Exit threshold: When to sell (default 45¢) - Max position: Amount per trade (default $2.00) - Locations: Which cities to trade (default NYC)

3. Save settings to environment variables

4. Set up cron (disabled by default — user must enable scheduling)

Configuration

| Setting | Environment Variable | Default | Description | |---------|---------------------|---------|-------------| | Entry threshold | SIMMER_WEATHER_ENTRY | 0.15 | Buy when price below this | | Exit threshold | SIMMER_WEATHER_EXIT | 0.45 | Sell when price above this | | Max position | SIMMER_WEATHER_MAX_POSITION | 2.00 | Maximum USD per trade | | Max trades/run | SIMMER_WEATHER_MAX_TRADES | 5 | Maximum trades per scan cycle | | Locations | SIMMER_WEATHER_LOCATIONS | NYC | Comma-separated cities | | Smart sizing % | SIMMER_WEATHER_SIZING_PCT | 0.05 | % of balance per trade |

Supported locations: NYC, Chicago, Seattle, Atlanta, Dallas, Miami

Quick Commands

# Check account balance and positions
python scripts/status.py
Detailed position list

Portfolio: GET /api/sdk/portfolio

Positions: GET /api/sdk/positions

Running the Skill

# Dry run (default — shows opportunities, no trades)

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

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 — 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: 1. Fetches active weather markets from Simmer API 2. Groups markets by event (each temperature day is one event) 3. Parses event names to get location and date 4. Fetches NOAA forecast for that location/date 5. Finds the temperature bucket that matches the forecast 6. Safeguards: Checks context for flip-flop warnings, slippage, time decay 7. Trend Detection: Looks for recent price drops (stronger buy signal) 8. Entry: If bucket price < threshold and safeguards pass → BUY 9. Exit: Checks open positions, sells if price > exit threshold 10. 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)

Get new key from simmer.markets/dashboard → SDK tab
