Margin changes before events: what did your broker do?
Brokers can raise margin requirements before volatile events, changing the economics of open positions overnight. The notice, the scope and the timing all vary.

- the broker and the event
- how much margin changed and when you were told

The margin guide explains the mechanics behind the change.
Background: Leverage and margin explained: margin calls, stop-outs and how losses grow
Leverage lets you control a large position with a small deposit. It magnifies losses exactly as much as gains, and it is behind most blown trading accounts.
What does 30:1 leverage mean?
You can control a position 30 times larger than your margin deposit. $1,000 of margin opens a $30,000 position, and gains and losses are calculated on the full $30,000.
What is a margin call?
A warning from your broker that losses have reduced your margin level to a set threshold. If it keeps falling, the broker starts closing positions automatically, which is called a stop-out.
