Evaluate after costs

Columns: date,resultR,costR. Result is gross R; cost is non-negative R. Dates use YYYY-MM-DD in chronological order. Multiple trades on one day are allowed. Up to 5,000 trades.

Each trade risks the chosen percentage of current equity. Flat trades count in the win-rate denominator. Profit factor uses net R. Simulation stops at zero equity; later rows are skipped. No price-feed backtest or account verification is performed.
