Which rule saved your USDJPY week most often?

USDJPY weeks go wrong in familiar ways: BOJ headline curiosity, intervention-rumour twitch, and sizing like a sleepy major when the tape is yen-special. Looking back across recent journals, the rule that saved me most often was not a clever entry pattern — it was a stand-aside timer around unexplained spikes.

Desk rule I keep returning to: if USDJPY jumps without a scheduled print and the spread widens beyond my filter, I am flat for a fixed number of minutes. No “fade the spike” improvisation while the book is broken. The journal shows those improvisations as the week’s damage more often than as the week’s genius. Size caps help; blackouts help more when the move is headline-driven.

Curious what actually protects other yen desks when the week is messy rather than textbook.

For your last decent USDJPY week, which single rule did the heavy lifting — blackout, size cap, time-stop, or something else?
