Field notes
The methodology page states that tests use the Nikkei 225 price index, exclude dividends, assume buy-only trades at the signal day's close, and include a 0.1% one-way cost. Readers can adjust rule parameters in the backtest tool and compare up to three rules. The site reports that none of 96 tested rules beat buy-and-hold on annualized return, while 87 had shallower maximum drawdowns.
