Glossary

Every metric in a Pancake receipt has a cited definition, a formula, and a worked example in a real backtest. Ten terms. No hand-waving.

Bootstrap Confidence IntervalResampling-based CI — no normality assumption required.
Brier ScoreMean squared error of probability forecasts — lower is sharper.
CAGRCompound Annual Growth Rate — your annualized return, apples-to-apples.
Maximum DrawdownThe worst peak-to-trough decline you would have suffered.
PCG64NumPy's default random generator — what makes Pancake bootstrap reproducible.
Permutation TestNon-parametric significance test: how often does shuffling beat your Sharpe?
Sharpe RatioRisk-adjusted return: excess return divided by total volatility.
Sortino RatioLike Sharpe, but only penalizes downside volatility.
Wilson Confidence IntervalThe right confidence interval for a win rate, especially at small N.
Win RateFraction of trades with positive P&L — not the same as a good strategy.

Pancake is a workflow runtime. Pancake is not a broker-dealer, investment advisor, or clearing firm. Pancake does not custody funds, execute trades on its own account, or provide investment advice. Orders are routed to your connected accounts using authorization you provide.

Trading involves risk, including loss of principal. Backtest results are hypothetical and reflect modeled assumptions. They exclude factors such as taxes, slippage, and execution timing. Past performance does not predict future results.
