Example: SMA Crossover on NVDA, 5-minute bars, Oct 5 to Oct 9, 2026.

The equity chart of the same run, with holding NVDA beside it: a return of +0.7% against -3.4%, a max drawdown of 2.6% against 5.5%, and in the market 83% of the time against 100%.
Example: SMA Crossover on NVDA, 5-minute bars, Oct 5 to Oct 9, 2026. The strategy made 0.7% and holding NVDA lost 3.4%.

On every run

Compare it with holding the stock.

Net P&L is after commissions and slippage, and holding the same stock is drawn on the same chart. With 30 trades or more, the result also shows whether luck alone could explain it.

A walk-forward test of Bollinger Breakout on SPY, profitable in 4 of 6 windows, with bbLength 55 chosen in every window. Below it, one backtest on the default settings: the strategy lost 8.4% while holding SPY made 12.5%, 90% of 2,000 redraws ended between -19.9% and +4.9%, and the average trade of -1.6 bp is not clearly different from zero.
Example: Bollinger Breakout on SPY, 5-minute bars, Jan 5 to Oct 5, 2026. Top: a walk-forward over 10 settings. Bottom: one backtest on the default settings.

On the Trader plan

Test your settings on dates they were not optimized on.

Optimize picks the best settings on one stretch of history and tests them on the next, then shows how many stretches stayed profitable.
