A good indicator of a healthy trading account is making sure that your Margin Level is always above 100%.
Margin Call is a notification you receive when your margin percentage actually reaches 100% and is endangering your account.
In order to avoid wiping out your trading account, you can:
Add funds to your account
Close some of your open trades at the current loss
Hedging (Hedging is where you open a position that goes against a current open position).
❗️If your margin % decreases to 50% you will have a Stop Out
