If you make a fixed investment on February 1 day, the data will be transmitted to the securities market on the second trading day, which means that your business was actually accepted by the fund company on February 2, so the first deduction was made at 9: 30 on March 1 day. If successful, the price you buy will be after the close of March 1.

The bank didn't make any mistakes. It turns out that any fixed investment does not include the day of application. You didn't pay the interest on your deposit and loan on the same day.
