■About Multiple of 5 in jap Gotobi

A Gotobi is a day that has a 5 or 10 in it.
In other words, "the 5th, 10th, 15th, 20th, 25th, and 30th".
According to Japanese business custom, the demand for funds increases on Gotobi.

The middle rate is determined by banks at 9:55 a.m. on every business day (Japan Standard Time).
The exchange rate at which the bank settles the transaction on that day is the value of the exchange rate.
The higher the rate, the more profitable it is for the bank if the dollar appreciates or depreciates against the yen.
Therefore, it is said that the dollar tends to appreciate against the yen at 9:55 a.m. on the 5th, 10th, 15th, 20th, 25th, and 30th of each Gotobi, when the middle price of the day is determined.
