How to receive order fill alerts
You can be immediately notified when an order fills by adjusting your settings in the trade settings menu (top-right of the trading form).
When one of your orders is filled, a small notification window appears on the bottom right hand of your screen. Fill notifications can be disabled, however, through the Trading Preferences menu 
, found at the top-right of the trading panel.
The option "Show fill notifications" can be turned on or off in the trade settings menu.
Cryptowatch can send you SMS text message alerts when one of your orders is filled. SMS alert settings can be configured through the Account menu, enabling you to change your phone number, as well as enable/disable the specific alerts you wish to receive.
