Your deposit will be reflected in your Abra wallet within 2-3 business days (excluding weekends and holidays), and your withdrawal will be reflected in your bank account within 3-5 business days (excluding weekends and holidays). There are no limitations, however on a rolling basis, which means they aren't reset at the start of the day. If you surpassed your limit at 3 p.m. the previous day, it will not be reset until after 3 p.m. the following day.
