Backtest Reporting Metrics for Futures and Stock Accounts

Code TqSdk

Summary

This report utility converts daily account snapshots and trade records into tables, then calculates summary statistics for simulated futures accounts or stock accounts. For both account types it derives daily profit and returns, cumulative profit and loss days, annualized return, maximum drawdown, and Sharpe, Sortino, and Calmar ratios. The futures path also counts opening and closing trades, averages account risk, and estimates win rate and profit-to-loss ratio from matched trades and contract multipliers; the stock path tracks buy and sell counts, fees, and winning and losing streak lengths.

The code also generates rolling risk-adjusted ratio chart data. Its stated scope is simulation reporting, and the available input records and quote metadata constrain what can be calculated. Metrics depend on the implementation’s assumptions, including annualization conventions and trade matching. The document is code rather than an empirical study: it provides no example results, validation, or guidance for interpreting the metrics, so users should confirm definitions and edge cases before relying on reports.

Key ideas

  • Daily account snapshots are combined with trade records to calculate performance statistics.
  • The report includes returns, drawdown, annualized risk-adjusted ratios, and streak counts.
  • Futures trade statistics use matched openings and closings plus contract multipliers.
  • Stock and futures accounts use different account fields and trade metrics.
  • Rolling Sharpe, Sortino, and Calmar chart data are generated, but no validation results are shown.
