**Closed Virtual Trades:** {json.dumps(trades, indent=2)}
**Closed Flags:** {json.dumps(flags_closed, indent=2)}
**Recent Macro Notes:** {json.dumps(notes, indent=2)}

Please analyze:
1. Which types of signals performed well? Which performed poorly?
2. Are there patterns in the flags accuracy vs. market type?
3. How well do the macro notes align with actual outcomes?
4. What concrete adjustments should the trading agent make (e.g., focus on certain sports/markets, adjust confidence threshold)?
