That is not always the case the mm on the top. They are suppose to fill in an orderly fashion but it doesn't always happen. An AON can be a GTC or a day buy. What it does is it only fills your entire order where you want it - no partials. So if you choose to use it, they will only fill it if they can fill it entirely. Check your trading platform and make sure you don't have that option checked as a default. If you are getting partial fills then you aren't using AON.
