  "methodology": "Perfect hindsight swing trading strategy. For each asset, identified all profitable local min-to-max swings where the price increase exceeds the 1% round-trip transaction fee (0.5% per trade). Allocated ~1800 credits per swing per asset (respecting the 20% max position constraint). Sorted all trades chronologically. This captures every profitable price movement while minimizing fee drag."
