MAE, maximum adverse excursion, is the furthest a trade moved against the position before it closed, while MFE, maximum favourable excursion, is the largest unrealised profit it reached. Together they provide the most direct available evidence on whether gold stops and targets are correctly placed, because they describe what happened inside the trade rather than only at its endpoints.
Winning XAUUSD trades that repeatedly approach the stop before working indicate stops too tight for current volatility, and trades reaching two and a half R of favourable excursion but closed at one R indicate an exit rule leaving measurable profit behind. Both values should be recorded in R rather than dollars so they remain comparable between quiet gold weeks and high-volatility periods around CPI and FOMC.
