Potential Loss for Isolated Margin
If you are using Isolated Margin, margin assigned to a position is restricted to the amount assigned to the position. For example, if you assign $100 to a position in an Isolated Margin, $100 is the maximum amount you could lose if you were liquidated.
Potential Loss for Cross Margin
Cross Margin, also known as “Spread Margin”, is a margin method that utilises the full amount of funds in the Available Balance to avoid liquidations - Any realised PNL from other positions can also aid in providing margin to a losing position. Therefore, when using Cross Margin, all your funds in your Available Balance will be lost if your position is liquidated.
