Replace 7 hardcoded 0.0 values with real calculations: - target_quantity from last close price - portfolio_volatility from log return stddev * sqrt(252) - portfolio_sharpe from weighted returns / portfolio vol - var_95 parametric VaR - max_drawdown_estimate from vol approximation - rebalance_delta as target - current (0 until positions available) - per-asset volatility from price bars (was hardcoded 0.15) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
