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.

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.

The Goto-day and month-end, around the midpoint of the dollar/yen, behaved differently｜Counted over 10 years and 710 days

【New Product Introduction】
We released the MT5 indicator that notifies you on your smartphone when the price hits the level, “Omakase水平線 Pro” (the product I sell).

There is a time in the USD/JPY when it moves best, every morning at9:55.

It is the time determined by banks for the day's exchange rate,the "Naka-ne" (level-rate)is called.

Gotō-bi (fifty-day)refers to days that end in5 and 10such as the 5th and 10th.

In Japan, payments between companies and settlement of prices tend to cluster on Gotō-bi and the end of the month.

Therefore in FX, it is often said that“Around Gotō-bi or the end of the month, the USD/JPY tends to rise toward the Naka-ne”.

Because importers buy dollars to pay overseas.

I checked whether this is really the case by counting ten years of USD/JPY data (October 2016 to September 2026).

Definitions used in this article

  • Gotō-bi: 5, 10, 15, 20, 25
  • End of month: the last business day of that month (such as 30th or 31st)
  • If it falls on a weekend or holiday, it is shifted to the previous business day for both cases
  • Before the Naka-ne:8:00–9:55After the Naka-ne:9:55–11:00

※ In dictionaries, Gotō-bi also includes the 30th, but in this article the 30th and 31st are categorized as “End of month.” Including the 30th as Gotō-bi gives almost the same results.


On Gotō-bi, “Before the Naka-ne” is different from “After the Naka-ne” at the end of the month


The dashed line represents ordinary days (not Gotō-bi or end of month).


Gotō-bi: days that rose before the Naka-ne 62%
End of month: days that fell after the Naka-ne 63%

Ordinary days: days that rose before the Naka-ne 54%, and days that fell after the Naka-ne 55%.

Gotō-bi and end of month together are about8 percentage points more likelythan ordinary days.

On the other hand,the days that rose before the Naka-ne at the end of the month are 52% and almost the same as ordinary days.

The claim that “the dollar rises before the Naka-ne at the end of the month” could not be confirmed in this decade.

※ Even on ordinary days the rise is a bit more than half because the USD/JPY has risen from about 101 to about 158 in this decade.

I use this 9:55 a.m. time as a “FX Voice Reminder” to read my own text at a set time (a product I sell).

When the Naka-ne moves significantly before and after, I also look at the prior high and low. The line is drawn automatically with the MT5 indicator “Omakase水平線” (the product I sell).

Next,the results of dividing ten years into one-year periods and a Gotō-bi and end-of-month calendar for Oct–Dec 2026 (printable PDF included) are presented.
