Cross margin
Cross margin is a futures setting where your whole available balance backs all open positions together. Liquidation sits further away, but when it comes it can take the entire balance.
With cross margin, a losing position keeps drawing on the rest of your account to stay open. That feels safer because liquidation is far away, but one bad trade, or a stop that does not fill, can empty the account instead of costing only one position’s margin, as isolated margin would.
