Simulated results on past data, with settings chosen on this same period. They are not live trading, include leverage, and are not a reliable indicator of future results. You can lose more than the backtest's worst drawdown.

The terms, briefly.
- Drawdown
- The fall from a previous high to the next low.
- Sharpe ratio
- Excess return relative to its fluctuation. Smoother, not safer.
- Walk-forward
- Tune on one period, test on the next unseen one.
- Overfitting
- Rules that learned noise. Great backtest, weak live.
- Slippage
- The gap between expected and filled price. A real cost.
