I will share how I will manage OCBC360 if I use it. Treat is a FD account, keep 100k at start, add 500 on first day every mth, collect interest. At end of year, reset to 100k, repeat.
If you dun want lose interest on the 500 every mth x12 mths, then start with 94k so at end of year you have 100k, then reset.
Also need to understand if OCBC have any cutoff time like movements on sundays/public holidays should these fall on the first day.
If salary come in, move out same day. Keep your daily spreadsheet to check just in case you forget anytime, make sure adb is correct
Keep it simple, live more bank less.
