Isolated margin
Isolated margin is a futures setting where each position has its own fixed margin. If the position is liquidated, you lose that margin and nothing else from your balance.
Open a position with 130 USDT of isolated margin and the most it can take from your account is those 130 USDT, even in a gap where your stop does not fill. The price of that fence is a liquidation price closer to your entry than with cross margin.
