In plain terms
A directional overlay on gold built around a directional-change signal, tested as an add-on rather than a standalone book.
How it works
A directional-change indicator flags regime shifts and a spare overlay leans with them; kept deliberately simple to limit overfitting.
What it’s tested against
Out-of-sample with stressed costs; judged on whether it adds anything beyond simply holding gold.
