Margin Call
The broker's warning (or automatic closeout) when your account loses too much and can no longer support your open trades.
The 2015 CHF unpeg sent thousands of retail accounts into negative balance. Brokers like Alpari UK went bankrupt overnight because so many traders had margin called at once.
