🛡️ Safety & Security

⚠️ Important Security Considerations

• Private Key Protection: Never share or commit your private key
• Start Small: Begin with small amounts ($50-100) to test
• Understand Markets: Only trade in markets you understand
• Monitor Positions: Check your positions regularly
• Use Safety Limits: Configure appropriate limits for your risk tolerance
• Never Risk More: Than you can afford to lose

Default Safety Limits

MAX_ORDER_SIZE_USD=1000              # Maximum $1,000 per order
MAX_TOTAL_EXPOSURE_USD=5000          # Maximum $5,000 total exposure
MAX_POSITION_SIZE_PER_MARKET=2000    # Maximum $2,000 per market
MIN_LIQUIDITY_REQUIRED=10000         # Minimum $10,000 market liquidity
MAX_SPREAD_TOLERANCE=0.05            # Maximum 5% spread
REQUIRE_CONFIRMATION_ABOVE_USD=500   # Confirm orders over $500

These can be customized in your .env file or Claude Desktop config.
