Fees are by default paid with the fiat money. This means that you bought crypto for the specified amount (e.g. 25 USD) and the fees are charged separately. When you want to spend 100 USD over 4 weeks, meaning 1 order per week, the last order won't be placed since there is not enough fiat money left. In my case I wanted to spend 100 EUR a month, meaning 25 € once per week. When testing it the first time I was charged 25,065 EUR. By setting the fee to XBT instead of EUR, I can run the script 4 times a month.
