You can specify a certain margin level at which a platform and mobile push notification will be triggered. The Margin utilisation alert value can be set up from the Account Summary module.
Click the Off to set it up, choose the alert level, and hit Submit button.
When the specified level is reached, an alert will be shown on the platform, and if you have the SaxoTrader mobile app with push notifications enabled, you will also receive the alert on your mobile device.
