Data & Methodology

What's behind every number in the Workbench: second-level options data, an independent backtest engine, a fully-disclosed parameter grid, and the honest caveats.

An analytics tool you can't interrogate is a black box with charts. This section documents what the numbers are made of — and, just as deliberately, where their limits are.

The pipeline, end to end

  1. Data — SPX 0DTE options market data at second-level (1-second) resolution, plus the official settlement prints. Coverage runs from May 2022 to the current data through date shown in the app. → The dataset & parameter grid
  2. Simulation — our own backtest engine replays every strategy variant against that data, trade by trade: scheduled entries, strikes selected from the actually-published option chain, intraday stop monitoring, cash settlement at the official close. → How a backtest runs
  3. Fill modeling — simulated fills are derived from the quoted market with conservative haircuts, and we continuously measure how our own live fills compare to the quoted market to keep the modeling honest. → Fills, stops & modeled P&L
  4. The catalog — the grid of 200,000+ parameter combinations is re-scored weekly, and every metric you see is computed over your selected period on a standardized $100k account.
  5. The caveats — hypothetical performance, selection bias at catalog scale, and what none of this can promise. → Known caveats & honest limits

The posture

Three commitments run through everything:

  • Same terms as the app. Definitions here (win rate, MAR, Sharpe, periods) are exactly what the Workbench computes — no marketing math.
  • Determinism. The same strategy configuration on the same dataset version produces identical results. When numbers change, it's because data arrived, not because a model drifted silently.
  • Education, not advice. Everything in the Workbench is hypothetical backtest output for research and education. It is not a recommendation, and past results — simulated or real — do not indicate future results.

Disclaimer

Cashflow Engine is analytics and educational software — not financial advice, and not an investment adviser, broker, or signal service. It issues no buy or sell recommendations and never holds or manages your money. Trading options carries substantial risk, including the loss of your entire investment. All backtests, simulations, and performance figures are hypothetical, are shown for research purposes, and do not indicate future results. Do your own research, understand the risks, and consult a licensed professional where appropriate. Your account, your decisions, your responsibility.
