A margin call is almost never an actual phone call anymore.
In modern online trading, a margin call is typically delivered through one or more of these:
1. Platform Notification (most common)
A pop-up alert inside your trading platform (MT4/MT5, cTrader, web app, etc.).
Often the first and only warning you get.
2. Email Notification
Many brokers send an automatic email when your margin level drops below the required threshold.
3. Push Notification
If your broker has a mobile app, you’ll usually get a push notification on your phone.
4. SMS (less common)
Some brokers let you enable SMS alerts.
5. Actual Phone Call (rare nowadays)
This used to be common when trading was done through human desks.
Today, phone calls are generally reserved for large/priority accounts or when the broker needs to urgently reach you — but this is not typical for standard retail accounts.
