FX trader and software engineer (25+ years in development) is Tack. I invested 500,000 yen in products and over 1,000,000 yen in the market. From there I rebuilt the rules, and started an account with 165,000 yen in May 2023, which went over 10,000,000 yen by March 2025 without any additional deposits. Looking back, many of the losses were not due to the method but due to execution mistakes like “forgot to draw the line” or “entered when the price wasn’t moving.” I’ve turned those tasks into a tool for myself. ━━━━━━━━━━ ■ Most-used tool [Leave-it-to-me Horizontal Line (MT5)] 1,280 yen I overslept and couldn’t draw the line, hurriedly entered, and incurred a drawdown. I created this from that mistake. Automatically draws horizontal lines at the high and low (no repaint). ━━━━━━━━━━ ■ Other tools ・FX Trade Alarm: countdown until the candle closes ・FX Voice Reminder: announces times you want to avoid by voice ・GC/DC Screener: bulk search for crosses across multiple instruments ■ Free ・Guide to drawing horizontal lines (PDF, 9 pages) ■ Serialized on Investment Navigator+ “Learn USD/JPY with examples and data”: using 5 and 10 years of data to study when prices move and stop.

Series
Learn USD/JPY with real examples and data
This ongoing series compiles viewpoints that can be used to judge trades based on actual USD/JPY charts and historical data (including convenient timeframes, days, and how to use horizontal lines). In some issues, a quick-reference table and a calendar (PDF) are attached for pre-trade checks. The chart lines are automatically drawn with the MT5 indicator "Okome Horizontal Line" (a product I sell). ※ It does not mean that past data will necessarily be the same in the future. This is not a recommendation to buy or sell.

Monday is quiet, Thursday is rough｜Dollar-Yen 10 years, 2,585 days reveal the “weekday habit”

[New Product Introduction]
I released the MT5 indicator "Omakase Horizontal Line Pro" that notifies you on your smartphone when your foot hits the horizontal line (this is a product I sell).

Even when entering with the same stop-loss width, on Mondays it didn’t arrive, and on Thursdays it hit the stop loss immediately.
Haven’t you had that kind of experience?

USD/JPY, and the daily movement range varies by day.

I counted 10 years of USD/JPY 5-minute bars (October 2016 to September 2026, on weekdays 2,585 days).

Terminology used in this article

  • Range: the difference between the day's high and low (1 pip = 0.01 yen)
  • Daily window: from 7:00 a.m. to 6:59 a.m. the next day Japan time (dividing at the close of the NY market)


Mondays are quiet, Thursdays are volatile


Monday: 91 pips
Thursday: 107 pips

Tuesday 95 pips, Wednesday 104 pips, Friday 103 pips.

Between Monday and Thursday, there is about a 1.2x difference in daily range.

Even when dividing by year, Mondays are quiet in 9 out of 10 years, while Thursdays are active in 9 out of 10 years. It doesn’t seem to be skewed by a particular year.

I use a browser app that announces times by voice, “FX Voice Reminder,” to read out the times to watch (this is a product I sell).

The daily difference is about 1.2x, but when looking only at the 21:00 hour in daylight saving time, the Monday-Thursday difference widens to about 1.6x.
In the continuation,

  • A printable “Day of the Week × Time Zone Quick Reference” (PDF, 2 pages)
  • On Mondays, 60% end up “upwards”, i.e., the rise/fall by day of week
  • Why Thursdays nights move a lot (there is a fixed time every week)
  • Based on these results, how I adjust my view of price range by day of week

is included.
