Risk Management

Configurable risk parameters in config.py (override via trading-config.json):

Parameter	Default	Description
-----------	---------	-------------
`max_daily_trades`	8	Max new trades per 24h window
`max_active_positions`	8	Max concurrent open positions
`trade_size_usd`	20	Trade size in USD
`take_profit_pct`	5.0	Auto take-profit trigger
`stop_loss_pct`	8.0	Auto stop-loss trigger
`max_drawdown_pct`	20.0	Portfolio-wide drawdown halt
`cooldown_minutes`	60	Cooldown between same-token trades
`min_liquidity`	50000	Minimum pool liquidity (USD)
`min_volume_24h`	100000	Minimum 24h volume filter

Key design decision: max_daily_trades should match max_active_positions. A mismatch (e.g., 4 daily trades but 8 position slots) means the bot hits its daily cap before filling available positions — leaving capital idle while signals pass. Align both limits for maximum capital efficiency.
