Isolated vs. cross margin in a few sentences:
In cross-margin mode, the entire balance of the same margin asset in your futures account backs your cross-margin positions, and losses can draw on the entire balance.
If one position in cross-margin mode has a large unrealized loss, it will use up balance that other positions also rely on, bringing all cross-margin positions closer to liquidation.
Check the margin mode for the trading pair before placing an order—don’t wait until something goes wrong to find out you’re using cross margin.
