What comes back
- Selections
- How many bets your theory would actually have made. Under 200 and there is no verdict.
- Yield ± 95% CI
- Profit per unit staked, with the interval. The interval is the part that decides it.
- p-value
- The odds a result this good came from luck alone.
- CLV
- Whether the price moved your way after you bet. Positive yield without it is usually luck.
- Equity curve
- The run of it — including the drawdown you would have had to sit through.
Backtests run against closing odds — Pinnacle for football, consensus for the NBA. Flat 1u stakes, minimum 200 selections before any verdict. A backtest is not an edge. It is the first filter, and most theories that survive it still die out of sample.
