USDJPY toward round numbers: magnet behavior notes

[LondonScalper]

USDJPY into round numbers -- magnet notes, not a call.

Yen crosses and USDJPY still show that pause-and-spike behaviour around big figures, especially when London and Tokyo narratives disagree. I mark the round and the nearby option-style handles people care about, then decide if my setup is before, through, or after acceptance.

Desk habits
Spread filter tightens near the figure. Market orders into the first touch have paid tuition. If price is magnetised and chopping the round, I wait for a clear session break rather than scalp every wick. Correlation with US yields can explain a run at the figure; it does not make the fill better.

I size down when the magnet is the only thesis. A round number alone is not an edge -- it is context for risk.

How do you trade (or avoid) USDJPY when it is glued to a big figure in London?

Option expiry days near big figures get an extra caution flag in my calendar notes. I do not pretend to model dealer hedging; I just assume path can be sticky or sudden. Size down, widen patience, or skip -- all better than forcing a normal scalp template onto a magnet day.
