Liquidation

Liquidation is the exchange closing a leveraged position by force, because its losses have used up nearly all of the margin behind it.

With 350 USDT of margin on a 3,500 USDT position, a 10% move against you uses the margin up, and the exchange closes the position a little before that. A long is liquidated with a sell, a short with a buy. Set your stop so it acts before liquidation does.
