Gold mean reversion is psychologically seductive because its high win rate produces long comfortable streaks while tail risk accumulates for a single trend-day loss.
Tracking average R and maximum drawdown rather than win rate, and framing each trade as a probability with a time-based expiry rather than an opinion about the "right" price, are the corrective habits.
A written pre-market regime classification, a re-check at 13:00 UTC, a log of correct stand-down days and a cooling rule after any loss above 1.5R keep the style survivable.
