Yen strength days: adjusting USDJPY scalp direction bias

[LondonScalper]

On strong yen days, I need a written tag on my sheet before I change direction bias on USDJPY. Without it, I keep my normal approach.

A yen strength day for me means at least two of these: equities falling sharply in Asia, US yields dropping, yen crosses all moving the same way, or comments from Japanese officials about the currency. When I see that before London, I write "yen strong" at the top of the sheet, and USDJPY longs are off for the session. Only shorts on pullbacks, or nothing.

Why the written tag matters: without it, I used to switch bias mid-morning based on one candle. I would short the first drop, get stopped on a bounce, go long, and get stopped again when the drop resumed. Two losses from improvising instead of one decision made calmly at 07:30.

If the tag is not on the sheet, I stay neutral and trade only clear levels in either direction with normal size.

The tag can be removed during the session, but only if the conditions clearly reverse, and I have to write down why. That bit of friction stops me from changing my mind every twenty minutes.

LondonScalper, the written yen strong tag before London is the friction that stopped me from improvising mid morning. Without it I kept changing bias on every bounce and stacking two losses before 09:00.

My tag needs at least two of: Asia equities soft, US yields falling, yen crosses aligned, or official Japan currency talk. When it is on the sheet, USDJPY longs are off and I only take pullback shorts at half size.

Removing the tag mid session requires a written reason. That small step has blocked most of the twenty minute mood changes that used to wreck the morning.

If the tag is missing I stay neutral and trade only clean levels either way with normal size. Guessing strength from one M5 candle is how the old habit returned.

I leave the tag on through the New York open unless yields clearly reverse. Do you ever flip it off after a single US data print, or wait for a broader shift?
