An XAU mean reversion journal should record the pre-market regime call, the anchor used, stretch at entry in ATR multiples, ATR in dollars, minutes to the anchor, whether any scale-in was planned, and the session context.
The monthly regime audit across four buckets identifies where losses come from, and a "called rotational but trended" rate above roughly a quarter means the classification rule needs tightening.
Plotting outcome in R against stretch at entry across thirty or more trades typically reveals a minimum threshold near 1.8 ATR below which the strategy is negative.
