AON (All or None Order) is a type of order in crypto trading that allows investors to cancel the entire order if it cannot be fully fulfilled.

AON (All or None Order) is an instruction in crypto trading that requires the entire order to be fulfilled in the amount requested, or if it is not fulfilled, the entire order will be canceled. In other words, the order will not be partially executed, but must be fulfilled completely or not at all.

This type of order gives investors the assurance that they will either get the desired amount of crypto assets or none at all. This is useful to avoid situations where orders are partially fulfilled, which can lead to unwanted risks and transaction costs.

AON orders are typically used for the purchase or sale of large amounts of crypto assets, where investors want to be sure that they get the entire desired amount or none at all.
