  "methodology": "I used a fee-aware dynamic program over all timesteps with perfect historical path information from the provided dataset. At each timestep, it selects the portfolio state (cash or a fully-allocated single asset) that maximizes terminal portfolio value under 0.5% buy/sell fees, then backtracks and emits executable buy/sell orders. This directly optimizes end value rather than using a heuristic indicator."
